Currently, all imx pinctrl drivers maintain a big array of struct imx_pin_reg which hard-codes data like register offset and mux mode setting for each pin function. Every time a new imx SoC support is added, we need to add such a big mount of data. With moving to single kernel build, it's only matter of time to be blamed on memory consuming. With DTC pre-processor support in place, the patch moves all these data into device tree by redefining the PIN_FUNC_ID in imxXX-pinfunc.h and changing the PIN_FUNC_ID parsing code a little bit. The pin id gets re-numbered based on mux register offset, or config register offset if the pin has no mux register, so that kernel can identify the pin id from register offsets provided by device tree. As a bonus point of the change, those arbitrary magic numbers standing for particular PIN_FUNC_ID in device tree sources are now replaced by macros to improve the readability of dts files.

Replace /include/ (dtc) with #include (C pre-processor) for all imx DT files, so that gcc -E handles the entire include tree, and hence any of those files can #include some other file e.g. for constant definitions. This allows future use of #defines and header files in order to define names for various constants, such as pinctrl settings. Use of those features will increase the readability of the device tree files. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>

The recent dtc+cpp support allows header files and C pre-processor defines/macros to be used when compiling device tree files. These headers will typically define various constants that are part of the device tree bindings. The original patch which set up the dtc+cpp include path only considered using those headers from device tree files. However, most are also useful for kernel code which needs to interpret the device tree. In both the DT files and the kernel, I'd like to include the DT-related headers in the same way, for example, <dt-bindings/gpio/tegra-gpio.h>. That will simplify any text which discusses the DT header locations. Creating a <dt-bindings/> for kernel source to use is as simple as placing files into include/dt-bindings/. However, when compiling DT files, the include path should be restricted so that only the dt-bindings path is available; arbitrary kernel headers shouldn't be exposed. For this reason, create a specific include directory for use by dtc+cpp, and symlink dt-bindings from there to the actual location of include/dt-bindings/. For want of a better location, place this "include chroot" into the existing dts/ directory. arch/*/boot/dts/include/dt-bindings -> ../../../../../include/dt-bindings Some headers used by device tree files may not be useful to the kernel; they may be used simply to aid in constructing the DT file (e.g. macros to create a node), but not define any information that the kernel needs to share. These may be placed directly into arch/*/boot/dts/ along with the DT files themselves.

The ab8500 device is a child of the prcmu device, which is a memory mapped bus device, whose children are addressable using physical memory addresses, not using mailboxes, so a mailbox number in the ab8500 node cannot be parsed by DT. Nothing uses this number, since it was only introduced as part of the failed attempt to clean up prcmu mailbox handling, and we can simply remove it.

Setting the reg-io-width to 1 byte represents more accurate description of the HW. This will fix an issue where UART driver causes kernel panic during bootup. Gregory CLEMENT traced the issue to autoconfig() in 8250.c, where the existence of FIFO is checked from UART_IIR register. The register is now read as 32-bit value as the reg-io-width is set to 4-bytes. The retuned value seems to contain bogus data for bits 31:8, causing the issue.

When DT support for kirkwood was first introduced, there was no clock infrastructure. As a result, we had to manually pass the clock-frequency to the driver from the device node. Unfortunately, on kirkwood, with minimal config or all module configs, clock-frequency breaks booting because of_serial doesn't consume the gate_clk when clock-frequency is defined. The end result on kirkwood is that runit gets gated, and then the boot fails when the kernel tries to write to the serial port. Fix the issue by removing the clock-frequency parameter from all kirkwood dts files. Booted on dreamplug without earlyprintk and successfully logged in via ttyS0.

BCM2835-ARM-Peripherals.pdf states that the I2C module's input clock is nominally 150MHz, and that value is currently reflected in bcm2835.dtsi. However, practical measurements show that the rate is actually 250MHz, and this agrees with various downstream kernels. Switch the I2C clock's frequency to 250MHz so that the generated bus clock rate is accurate. Signed-off-by: Stephen Warren <swarren@wwwdotorg.org> Signed-off-by: Olof Johansson <olof@lixom.net>
