This patchset adds:
- define the CPU name for Chromebook Peach Pi as Exynos5800
- set the cpu id of Exynos5422 to 0x5422
- S2MPS11 PMIC I/O driver
- Exynos5420-compatible (9-channel, 12-bit) ADC driver
- board detection for Odroid XU3 / XU3lite / XU4

This was tested on Odroid XU3 and XU3 Lite, without the XU4, but I'm waiting for reply from the Odroid forum users.

Tested with buildman for samsung.

Thanks for these patches.

At the last moment I got this to work on my odroidxu3 board.

One problem I would like to address out is usb smsc95xx ethernet is not getting started at the boot.

# usb start                   /* command failed at the start */

I will give it a try with latest kernel and let you know how it worked on Odroid-XU4 / XU4.
