From: Hans de Goede Date: Sat, 5 Sep 2015 14:55:51 +0000 (+0200) Subject: ARM: dts: sunxi: Add sun?i-q8-common.dtsi files for q8 tablets X-Git-Tag: firefly_0821_release~176^2~728^2~51^2~37 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=72df94cbec320860f759258b5677f72caa5d4777;p=firefly-linux-kernel-4.4.55.git ARM: dts: sunxi: Add sun?i-q8-common.dtsi files for q8 tablets Cheap allwinner based devices in the q8 enclosure come in many variants, all sharing the case and a number of other basic features. They differ in the display, touchscreen, accelerometer and wifi chips used. This commit adds 2 dtsi files defining the shared features of all the q8 tablets. sunxi-q8-common.dtsi defines features shared amongst all q8 tablets, sun8i-q8-common.dtsi defines features shared amongst all a23 / a33 based q8 tablets, but not with a13 q8 based tablets. a13 based tablets use a different card-detect pin for the mmc, and use uart1 instead of the r_uart for the serial console.
