Hi,

This series is very wanted by Android tablet devices from Acer, Asus and
other vendors which use Maxtouch 1386 controller. Touchscreens don't
work without the wakeup support, i.e. without this series. The wakeup
support is implemented in accordance to the datasheet and touchscreens
are working excellent using these patches.

Could you please take this series into v5.13?

Or could you please let me know what exactly needs to be improved?

Thanks in advance.
