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 25217fef35 ("ARM: dts: disable CCI on exynos5420 based
arndale-octa").
