The 7" Q8 tablet enclosure is used for a ton of slightly different cheap chinese tablets. There are some differences in which accelerometer / wifi is used, but other then that these are all the same from a u-boot / kernel pov. When we get to adding accelerometer support the plan is to add some kind of autodetection and mangle the dt accordingly (likely using the new quirks mechanism). For now this is a non issue as we do not yet have accelerometer support, and in the future, some sort of auto-detect is the way to go as we cannot expect users to exactly know what is inside their tablet. The dts files this commit adds are identical to the ones submitted to the upstream kernel. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>
