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.

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. Reported-by:
