>Chagall WiFi, with product name Samsung Galaxy Tab S 10.5", is based on

>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, see commit
>25217fef3551 ("ARM: dts: disable CCI on exynos5420 based arndale-octa").

Nit: remove extra line here
Not sure if you need to re-spin the patch or may be Krzysztof will fix this
will applying
Rest looks fine.
