      ARM: OMAP3: Beagle: fix OPP customization and initcall ordering · 65bf7ca0
      Kevin Hilman authored 
      After commit 24d7b40a

 (ARM: OMAP2+:
PM: MPU DVFS: use generic CPU device for MPU-SS), OPPs are registered
using an existing CPU device, not the omap_device for MPU-SS.

First, fix the board file to use get_cpu_device() as required by the
above commit, otherwise custom OPPs will be added to the wrong device.

Second, the board files OPP init is called from the its init_machine
method, and the generic CPU devices are not yet created when
init_machine is run.  Therefore OPP initialization will fail.  To fix,
use a device_initcall() for the board file's OPP customization, and
make the device_initcall board-specific by using a machine_is check.

      ARM: OMAP3: Fix 3430 legacy mux names for ssi1 signals. · 1d8643dd
      Tony Lindgren authored 
      

On n900 uart1 pins are not not used for uart, instead they are
used to connect to a cell modem over ssi. Looks like we're
currently missing these signal names for 3430 for some reason,
and only have some of them listed for 3630. Obviously the signals
are there for 3430 if n900 is using them and they are documented
in some TRMs.

Note that these will eventually be replaced by device tree
based pinctrl-single.c driver. But for now these are needed
to verify the SSI pins for devices like Nokia N900.

      ARM/dts: omap3: Fix mcbsp2/3 hwmods to be able to probe the drivers for audio · eef6fcaa
      Peter Ujfalusi authored 
      

Fixes the following errors:
[    2.318084] omap-mcbsp 49022000.mcbsp: invalid rx DMA channel
[    2.324432] omap-mcbsp 49024000.mcbsp: invalid rx DMA channel

Which is because we failed to link the sidetone hwmod for McBSP2/3. The
missing sidetone hwmod link will prevent omap_device_alloc() to append the
DMA resources since we - accidentally - end up having the same number of
resources provided from DT (IO/IRQ) as we have in hwmod for the McBSP ports
without the ST resources.

      ARM: OMAP2: UART: fix console UART mismatched runtime PM status · 44b1d42a
      Kevin Hilman authored 
      

The runtime PM framework assumes that the hardware state of devices
when initialized is disabled.  For all omap_devices, we idle/disable
device by default.  However, the console uart uses a "no idle" option
during omap_device init in order to allow earlyprintk usage to work
seamlessly during boot.

Because the hardware is left partially enabled after init (whatever
the bootloader settings were), the omap_device should later be fully
initialized (including mux) and the runtime PM framework should be
told that the device is active, and not disabled so that the hardware
state is in sync with runtime PM state.

To fix, after the device has been created/registered, call
omap_device_enable() to finialize init and use pm_runtime_set_active()
to tell the runtime PM core the device is enabled.

Tested on 2420/n810, 3530/Overo, 3530/Beagle, 3730/OveroSTORM,
3730/Beagle-xM, 4460/PandaES.

      ARM: OMAP3: PM: apply part of the erratum i582 workaround · 856c3c5b
      Paul Walmsley authored 
      

On OMAP34xx/35xx, and OMAP36xx chips with ES < 1.2, if the PER
powerdomain goes to OSWR or OFF while CORE stays at CSWR or ON, or if,
upon chip wakeup from OSWR or OFF, the CORE powerdomain goes ON before
PER, the UART3/4 FIFOs and McBSP2/3 SIDETONE memories will be
unusable.  This is erratum i582 in the OMAP36xx Silicon Errata
document.

This patch implements one of several parts of the workaround: the
addition of the wakeup dependency between the PER and WKUP
clockdomains, such that PER will wake up at the same time CORE_L3
does.

This is not a complete workaround.  For it to be complete:

1. the PER powerdomain's next power state must not be set to OSWR or
   OFF if the CORE powerdomain's next power state is set to CSWR or
   ON;

2. the UART3/4 FIFO and McBSP2/3 SIDETONE loopback tests should be run
   if the LASTPOWERSTATEENTERED bits for PER and CORE indicate that
   PER went OFF while CORE stayed on.  If loopback tests fail, then
   those devices will be unusable until PER and CORE can undergo a
   transition from ON to OSWR/OFF and back ON.

      arm64: fix alignment padding in assembly code · aeed41a9
      Marc Zyngier authored 
      

An interesting effect of using the generic version of linkage.h
is that the padding is defined in terms of x86 NOPs, which can have
even more interesting effects when the assembly code looks like this:

ENTRY(func1)
	mov	x0, xzr
ENDPROC(func1)
	// fall through
ENTRY(func2)
	mov	x0, #1
	ret
ENDPROC(func2)

Admittedly, the code is not very nice. But having code from another
architecture doesn't look completely sane either.

The fix is to add arm64's version of linkage.h, which causes the insertion
of proper AArch64 NOPs.

Pull perf/urgent fixes from Arnaldo Carvalho de Melo:

* The python binding needs to link with libtraceevent and to initialize
  the 'page_size' variable so that mmaping works again.

* The callchain folding character that appears on the TUI just before
  the overhead had disappeared due to recent changes, add it back.

* Intel PEBS in VT-x context uses the DS address as a guest linear address,
  even though its programmed by the host as a host linear address. This either
  results in guest memory corruption and or the hardware faulting and 'crashing'
  the virtual machine.  Therefore we have to disable PEBS on VT-x enter and
  re-enable on VT-x exit, enforcing a strict exclude_guest.

  Kernel side enforcement fix by Peter Zijlstra, tooling side fix by David Ahern.

* Fix build on sparc due to UAPI, fix from David Miller.

* Fixes for the srclike sort key for unresolved symbols and when processing
  samples in JITted code, where we don't have an ELF file, just an special
  symbol table, fixes from Namhyung Kim.

* Fix some leaks in libtraceevent, from Steven Rostedt.
