Chagallwifi, with product name Samsung Galaxy Tab S 10.5", is based on
Exynos 5420. This device is one of several tablet models released in
2013 - 2014 based on Exynos 5420.

The device tree added here contains support for:

- UART
- eMMC
- SD card
- USB

CCI has been disabled in the hardware, enabling it would require
(de-)soldering a resistor on the board.  Trying to boot with it
enabled in kernel makes the device hang when CCI is probed.
Exynos5420-arndale-octa also has had CCI disabled due to issues [1].

To successfully boot the mainline kernel with the stock bootloader
(SBOOT), an additional hack is needed [2]. The same hack is also
needed to boot exynos4412-i9300 with stock bootloader, and probably
other Samsung devices of similar age.

Thanks for the patches. It is a really nice work, good job!

Commits should use 'commit SHA_12char ("subject")' format instead of
links to mailing lists.

The name is something like Chagall WiFi, Chagall-WiFi or other
variations, because the device family name is Chagall and WiFi is variant.
Therefore here, patch 1/3, the compatible and all names, please make:
 - exynos5420-chagall-wifi.dtb
 - "samsung,chagall-wifi"
etc.

Please define these regulator nodes in DTSI (only name needed and

Skip the compatible. It duplicates exynos5420.dtsi and does not bring
any more information here.

Just keep one clock - oscclk. We treat it as alias of xxti, even though
it might not be exactly alias. I am not sure about real differences, but
anyway the driver does not care about xxti and xusbxti. xusbxti appears
in Exynos5420 only partially, e.g. not in all places like ballmap. Other
boards have only oscclk, so let's do the same.

All regulators should be under node "regulators". It should not work
properly without it, e.g. check
/sys/kernel/debug/regulator/regulator_summary if values match ones you
define.

Property is deprecated and I am not sure what is it's purpose since, the
regulator is off in suspend.

Do it like ldo25 in arch/arm/boot/dts/exynos4412-midas.dtsi. Comment is
good.

Name is 1.8V, voltage is 1.9V. Double check this one :)

I think these two are not supported properties.

You should define here also pins, something like Arndale Octa has.
