This dts file is based on the Snow dts file in the Chromium OS kernel tree with the following changes: * Some details have been updated to match the exynos5250-smdk5250.dts file from linux-next (as of c11068538994430547722dc9fb515a0ceefd5cb9). * This file doesn't include references to hardware whose upstream support isn't quite there yet. That includes most i2c devices. Note that most i2c busses have been included with no devices. The Snow dts file is mostly just an include of the "cros5250" dts file which describes a class of similar boards. Support for other boards has not yet been send upstream. With this file and a change to use UART3 for serial output I can: * Boot to a command line using either SD or EMMC as a root filesystem * See the power button and lid switch using evtest.

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.

Commit 9e3c0066 (ARM: dts: imx6q-arm2: add pinctrl for uart and enet) defines NANDF_CS pins as gpio in 'hog', assuming these two pins are always used by usdhc3 in gpio mode as card-detection and write-protection on ARM2 board. But it's not true. These pins are shared by usdhc3 and gpmi-nand. We should have the pins functional for gpmi-nand when usdhc3 is disabled. Move the pins out of 'hog', so that pins only work in gpio mode as CD and WP when usdhc3 is enabled, and otherwise they are available for gpmi-nand. Reported-by:

This patch reworks wake-up interrupt handling in pinctrl-exynos driver, so each pin bank, which provides wake-up interrupts, has its own IRQ domain. Information about whether given pin bank provides wake-up interrupts, how many and whether they are separate or muxed are parsed from device tree. It gives following advantages: - interrupts can be specified in device tree in a more readable way, e.g. : device { /* ... */ interrupt-parent = <&gpx2>; interrupts = <4 0>; /* ... */ }; - the amount and layout of interrupts is not hardcoded in the code anymore, but defined in SoC-specific structure - bank and pin of each wake-up interrupt can be easily identified, to allow operations, such as setting the pin to EINT function, from irq_set_type() callback Signed-off-by:

Instead of registering one IRQ domain for all pin banks of a pin controller, this patch implements registration of per-bank domains. At a cost of a little memory overhead (~2.5KiB for all GPIO interrupts of Exynos4x12) it simplifies driver code and device tree sources, because GPIO interrupts can be now specified per banks. Example: device { /* ... */ interrupt-parent = <&gpa1>; interrupts = <3 0>; /* ... */ }; Signed-off-by:

This uses the "kecho" macro that the build system provides to hide a few informational messages. Nothing changes for a regular "make" or "make V=1".
