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