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").
