+		path for a device using the information returned from
+		stat(2).  There are two directories, 'block' and 'char',
+		beneath /sys/dev containing symbolic links with names of
+		the form "<major>:<minor>".  These links point to the
+		corresponding sysfs path for the given device.
+
+		Example:
+		$ readlink /sys/dev/block/8:32
+		../../block/sdc
+
+		Entries in /sys/dev/char and /sys/dev/block will be
+		dynamically created and destroyed as devices enter and

+SH7760/SH7763 integrated LCDC Framebuffer driver
+================================================
+
+0. Overwiew
+-----------
+The SH7760/SH7763 have an integrated LCD Display controller (LCDC) which
+supports (in theory) resolutions ranging from 1x1 to 1024x1024,
+with color depths ranging from 1 to 16 bits, on STN, DSTN and TFT Panels.
+
+Caveats:
+* Framebuffer memory must be a large chunk allocated at the top
+  of Area3 (HW requirement). Because of this requirement you should NOT
+  make the driver a module since at runtime it may become impossible to
+  get a large enough contiguous chunk of memory.
+
+* The driver does not support changing resolution while loaded
+  (displays aren't hotpluggable anyway)
+
+* Heavy flickering may be observed
+  a) if you're using 15/16bit color modes at >= 640x480 px resolutions,
+  b) during PCMCIA (or any other slow bus) activity.
+
+* Rotation works only 90degress clockwise, and only if horizontal
+  resolution is <= 320 pixels.

+        Documentation/fb/sh7760fb.txt
+
+1. Platform setup
+-----------------
+SH7760:
+ Video data is fetched via the DMABRG DMA engine, so you have to
+ configure the SH DMAC for DMABRG mode (write 0x94808080 to the
+ DMARSRA register somewhere at boot).
+
+ PFC registers PCCR and PCDR must be set to peripheral mode.
+ (write zeros to both).
+
+The driver does NOT do the above for you since board setup is, well, job
+of the board setup code.
+
+2. Panel definitions
+--------------------
+The LCDC must explicitly be told about the type of LCD panel
+attached.  Data must be wrapped in a "struct sh7760fb_platdata" and
+passed to the driver as platform_data.
+
+Suggest you take a closer look at the SH7760 Manual, Section 30.

 The following list of chips is thought to be supported although not all are
 tested:
 
-those from the Image series with Cyber in their names - accelerated

-the newer CyberBladeXP family  - nonaccelerated

+those from the Image series and with Cyber in their names
+those with Blade in their names (Blade3D,CyberBlade...)
+the newer CyberBladeXP family
+
+All families are accelerated. Only PCI/AGP based cards are supported,
+none of the older Tridents.
+The driver supports 8, 16 and 32 bits per pixel depths.
+The TGUI family requires a line length to be power of 2 if acceleration
+is enabled. This means that range of possible resolutions and bpp is
+limited comparing to the range if acceleration is disabled (see list
+of parameters below).
+
+Known bugs:
+1. The driver randomly locks up on 3DImage975 chip with acceleration
+   enabled. The same happens in X11 (Xorg).
+2. The ramdac speeds require some more fine tuning. It is possible to
+   switch resolution which the chip does not support at some depths for
+   older chips.

+APM or ACPI?
+------------
+If you have a relatively recent x86 mobile, desktop, or server system,
+odds are it supports either Advanced Power Management (APM) or
+Advanced Configuration and Power Interface (ACPI).  ACPI is the newer
+of the two technologies and puts power management in the hands of the
+operating system, allowing for more intelligent power management than
+is possible with BIOS controlled APM.
+
+The best way to determine which, if either, your system supports is to
+build a kernel with both ACPI and APM enabled (as of 2.3.x ACPI is
+enabled by default).  If a working ACPI implementation is found, the
+ACPI driver will override and disable APM, otherwise the APM driver
+will be used.
+
+No, sorry, you cannot have both ACPI and APM enabled and running at
+once.  Some people with broken ACPI or broken APM implementations
+would like to use both to get a full set of working features, but you
+simply cannot mix and match the two.  Only one power management
+interface can be in control of the machine at once.  Think about it..
+
+User-space Daemons
+------------------
+Both APM and ACPI rely on user-space daemons, apmd and acpid
+respectively, to be completely functional.  Obtain both of these
+daemons from your Linux distribution or from the Internet (see below)
+and be sure that they are started sometime in the system boot process.
+Go ahead and start both.  If ACPI or APM is not available on your
+system the associated daemon will exit gracefully.

-Driver Interface -- OBSOLETE, DO NOT USE!
-----------------*************************
-
-Note: pm_register(), pm_access(), pm_dev_idle() and friends are
-obsolete. Please do not use them. Instead you should properly hook
-your driver into the driver model, and use its suspend()/resume()
-callbacks to do this kind of stuff.
-
-If you are writing a new driver or maintaining an old driver, it
-should include power management support.  Without power management
-support, a single driver may prevent a system with power management
-capabilities from ever being able to suspend (safely).
-
-Overview:
-1) Register each instance of a device with "pm_register"
-2) Call "pm_access" before accessing the hardware.
-   (this will ensure that the hardware is awake and ready)
-3) Your "pm_callback" is called before going into a
-   suspend state (ACPI D1-D3) or after resuming (ACPI D0)
-   from a suspend.
-4) Call "pm_dev_idle" when the device is not being used
-   (optional but will improve device idle detection)
-5) When unloaded, unregister the device with "pm_unregister"
-

-Driver Details
---------------
-This is just a quick Q&A as a stopgap until a real driver writers'
-power management guide is available.
-
-Q: When is a device suspended?
-
-Devices can be suspended based on direct user request (eg. laptop lid
-closes), system power policy (eg.  sleep after 30 minutes of console
-inactivity), or device power policy (eg. power down device after 5
-minutes of inactivity)
-
-Q: Must a driver honor a suspend request?
-
-No, a driver can return -EBUSY from a suspend request and this
-will stop the system from suspending.  When a suspend request
-fails, all suspended devices are resumed and the system continues
-to run.  Suspend can be retried at a later time.
-
-Q: Can the driver block suspend/resume requests?
-
-Yes, a driver can delay its return from a suspend or resume
-request until the device is ready to handle requests.  It
-is advantageous to return as quickly as possible from a
-request as suspend/resume are done serially.
-
-Q: What context is a suspend/resume initiated from?
-
-A suspend or resume is initiated from a kernel thread context.
-It is safe to block, allocate memory, initiate requests
-or anything else you can do within the kernel.
-
-Q: Will requests continue to arrive after a suspend?
-
-Possibly.  It is the driver's responsibility to queue(*),
-fail, or drop any requests that arrive after returning
-success to a suspend request.  It is important that the
-driver not access its device until after it receives
-a resume request as the device's bus may no longer
-be active.
-
-(*) If a driver queues requests for processing after
-    resume be aware that the device, network, etc.
-    might be in a different state than at suspend time.
-    It's probably better to drop requests unless
-    the driver is a storage device.
-
-Q: Do I have to manage bus-specific power management registers
-
-No.  It is the responsibility of the bus driver to manage
-PCI, USB, etc. power management registers.  The bus driver
-or the power management subsystem will also enable any
-wake-on functionality that the device has.
-
-Q: So, really, what do I need to do to support suspend/resume?
-
-You need to save any device context that would
-be lost if the device was powered off and then restore
-it at resume time.  When ACPI is active, there are
-three levels of device suspend states; D1, D2, and D3.
-(The suspend state is passed as the "data" argument
-to the device callback.)  With D3, the device is powered
-off and loses all context, D1 and D2 are shallower power
-states and require less device context to be saved.  To
-play it safe, just save everything at suspend and restore
-everything at resume.
-
-Q: Where do I store device context for suspend?
-
-Anywhere in memory, kmalloc a buffer or store it
-in the device descriptor.  You are guaranteed that the
-contents of memory will be restored and accessible
-before resume, even when the system suspends to disk.
-
-Q: What do I need to do for ACPI vs. APM vs. etc?
-
-Drivers need not be aware of the specific power management
-technology that is active.  They just need to be aware
-of when the overlying power management system requests
-that they suspend or resume.
-
-Q: What about device dependencies?
-
-When a driver registers a device, the power management
-subsystem uses the information provided to build a
-tree of device dependencies (eg. USB device X is on
-USB controller Y which is on PCI bus Z)  When power
-management wants to suspend a device, it first sends
-a suspend request to its driver, then the bus driver,
-and so on up to the system bus.  Device resumes
-proceed in the opposite direction.
-
-Q: Who do I contact for additional information about
-   enabling power management for my specific driver/device?

-System Interface -- OBSOLETE, DO NOT USE!
-----------------*************************
-If you are providing new power management support to Linux (ie.
-adding support for something like APM or ACPI), you should
-communicate with drivers through the existing generic power
-management interface.

+X - Specifying Device Power Management Information (sleep property)
+===================================================================
+
+Devices on SOCs often have mechanisms for placing devices into low-power
+states that are decoupled from the devices' own register blocks.  Sometimes,
+this information is more complicated than a cell-index property can
+reasonably describe.  Thus, each device controlled in such a manner
+may contain a "sleep" property which describes these connections.
+
+The sleep property consists of one or more sleep resources, each of
+which consists of a phandle to a sleep controller, followed by a
+controller-specific sleep specifier of zero or more cells.
+
+The semantics of what type of low power modes are possible are defined
+by the sleep controller.  Some examples of the types of low power modes
+that may be supported are:
+
+ - Dynamic: The device may be disabled or enabled at any time.
+ - System Suspend: The device may request to be disabled or remain
+   awake during system suspend, but will not be disabled until then.
+ - Permanent: The device is disabled permanently (until the next hard
+   reset).
+
+Some devices may share a clock domain with each other, such that they should
+only be suspended when none of the devices are in use.  Where reasonable,
+such nodes should be placed on a virtual bus, where the bus has the sleep
+property.  If the clock domain is shared among devices that cannot be
+reasonably grouped in this manner, then create a virtual sleep controller
+(similar to an interrupt nexus, except that defining a standardized
+sleep-map should wait until its necessity is demonstrated).

+
+On CPM1 devices, all ports are using slightly different register layouts.
+Ports A, C and D are 16bit ports and Ports B and E are 32bit ports.
+
+On CPM2 devices, all ports are 32bit ports and use a common register layout.

+  apply to "fsl,mpc8641d-pmc".
+
+  Compatibility does not include bit assigments in SCCR/PMCDR/DEVDISR; these
+  bit assigments are indicated via the sleep specifier in each device's
+  sleep property.
+
+- reg: For devices compatible with "fsl,mpc8349-pmc", the first resource
+  is the PMC block, and the second resource is the Clock Configuration
+  block.
+
+  For devices compatible with "fsl,mpc8548-pmc", the first resource
+  is a 32-byte block beginning with DEVDISR.
+
+- interrupts: For "fsl,mpc8349-pmc"-compatible devices, the first
+  resource is the PMC block interrupt.
+
+- fsl,mpc8313-wakeup-timer: For "fsl,mpc8313-pmc"-compatible devices,
+  this is a phandle to an "fsl,gtm" node on which timer 4 can be used as
+  a wakeup source from deep sleep.
+
+Sleep specifiers:
+
+  fsl,mpc8349-pmc: Sleep specifiers consist of one cell.  For each bit
+  that is set in the cell, the corresponding bit in SCCR will be saved
+  and cleared on suspend, and restored on resume.  This sleep controller
+  supports disabling and resuming devices at any time.
+
+  fsl,mpc8536-pmc: Sleep specifiers consist of three cells, the third of
+  which will be ORed into PMCDR upon suspend, and cleared from PMCDR
+  upon resume.  The first two cells are as described for fsl,mpc8578-pmc.
+  This sleep controller only supports disabling devices during system
+  sleep, or permanently.
+
+  fsl,mpc8548-pmc: Sleep specifiers consist of one or two cells, the
+  first of which will be ORed into DEVDISR (and the second into
+  DEVDISR2, if present -- this cell should be zero or absent if the
+  hardware does not have DEVDISR2) upon a request for permanent device
+  disabling.  This sleep controller does not support configuring devices
+  to disable during system sleep (unless supported by another compatible
+  match), or dynamically.

+	   this problem, because the "build-id" support will put some data
+	   into the "notes" segment (at a non-zero load address).
+
+	   To work around this, we force some data into both the "dummy"
+	   segment and the kernel segment, so the dummy segment will get a
+	   non-zero load address.  It's not enough to always create the
+	   "notes" segment, since if nothing gets assigned to it, its load

-This port to the NEC V850E processor supports the following platforms:
-
-   "sim"
-	The gdb v850e simulator (CONFIG_V850E_SIM).
-
-   "rte-ma1-cb"
-	The Midas labs RTE-V850E/MA1-CB and RTE-V850E/NB85E-CB evaluation
-	boards (CONFIG_RTE_CB_MA1 and CONFIG_RTE_CB_NB85E).  This support
-	has only been tested when running with the Multi-debugger monitor
-	ROM (for the Green Hills Multi debugger).  The optional NEC
-	Solution Gear RTE-MOTHER-A motherboard is also supported, which
-	allows PCI boards to be used (CONFIG_RTE_MB_A_PCI).
-
-   "rte-me2-cb"
-	The Midas labs RTE-V850E/ME2-CB evaluation board (CONFIG_RTE_CB_ME2).
-     	This has only been tested using a kernel downloaded via an ICE
-     	connection using the Multi debugger.  Support for the RTE-MOTHER-A is
-     	present, but hasn't been tested (unlike the other Midas labs cpu
-     	boards, the RTE-V850E/ME2-CB includes an ethernet adaptor).
-
-   "as85ep1"
-	The NEC AS85EP1 V850E evaluation chip/board (CONFIG_V850E_AS85EP1).
-
-   "anna"
-	The NEC `Anna' (board/chip) implementation of the V850E2 processor
-	(CONFIG_V850E2_ANNA).
-
-   "sim85e2c", "sim85e2s"
-   	The sim85e2c and sim85e2s simulators, which are verilog simulations
-	of the V850E2 NA85E2C/NA85E2S cpu cores (CONFIG_V850E2_SIM85E2C and
-	CONFIG_V850E2_SIM85E2S).
-
-   "fpga85e2c"
-	A FPGA implementation of the V850E2 NA85E2C cpu core
-	(CONFIG_V850E2_FPGA85E2C).
-
-To get a default kernel configuration for a particular platform, you can
-use a <platform>_defconfig make target (e.g., "make rte-me2-cb_defconfig");
-to see which default configurations are possible, look in the directory
-"arch/v850/configs".
-
-Porting to anything with a V850E/MA1 or MA2 processor should be simple.
-See the file <asm-v850/machdep.h> and the files it includes for an example of
-how to add platform/chip-specific support.

+ * The Maxim's MAX7301 device is an SPI driven GPIO expander. There are
+ * 28 GPIOs. 8 of them can trigger an interrupt. See datasheet for more
+ * details
+ * Note:
+ * - DIN must be stable at the rising edge of clock.
+ * - when writing:
+ *   - always clock in 16 clocks at once
+ *   - at DIN: D15 first, D0 last
+ *   - D0..D7 = databyte, D8..D14 = commandbyte
+ *   - D15 = low -> write command
+ * - when reading
+ *   - always clock in 16 clocks at once
+ *   - at DIN: D15 first, D0 last
+ *   - D0..D7 = dummy, D8..D14 = register address
+ *   - D15 = high -> read command
+ *   - raise CS and assert it again
+ *   - always clock in 16 clocks at once
+ *   - at DOUT: D15 first, D0 last
+ *   - D0..D7 contains the data from the first cycle
+ *
+ * The driver exports a standard gpiochip interface

+ *
+ * - Second there's its limited range (we could increase it a bit by
+ *   relying on WDAY), which means it will easily roll over.
+ *
+ * - Third there's the choice of two alarms and alarm signals.
+ *   Here we use ALM0 and expect that nINT0 (open drain) is used;
+ *   that's the only real option for DS1306 runtime alarms, and is
+ *   natural on DS1305.
+ *
+ * - Fourth, there's also ALM1, and a second interrupt signal:
+ *     + On DS1305 ALM1 uses nINT1 (when INTCN=1) else nINT0;
+ *     + On DS1306 ALM1 only uses INT1 (an active high pulse)
+ *       and it won't work when VCC1 is active.
+ *
+ *   So to be most general, we should probably set both alarms to the
+ *   same value, letting ALM1 be the wakeup event source on DS1306
+ *   and handling several wiring options on DS1305.
+ *
+ * - Fifth, we support the polled mode (as well as possible; why not?)

   Code in this driver inspired by and in a number of places taken
   from Brian Warner's original Keyspan-PDA driver.
 
   This driver has been put together with the support of Innosys, Inc.
   and Keyspan, Inc the manufacturers of the Keyspan USB-serial products.
   Thanks Guys :)

-   forcing gcc to do arithmetic on the value is usually enough to get it

- *  data: The data segment follows next.  We use current->end_text to
- *	current->brk to pick up all of the user variables, plus any memory
- *	that may have been sbrk'ed.  No attempt is made to determine if a
- *	page is demand-zero or if a page is totally unused, we just cover
- *	the entire range.  All of the addresses are rounded in such a way
- *	that an integral number of pages is written.
- *  stack: We need the stack information in order to get a meaningful
- *	backtrace.  We need to write the data from usp to
- *	current->start_stack, so we round each of these in order to be able
