Add several enhancements to the Goodix touchscreen driver:
- write configuration data to the device
- power management support
- cleanup and refactoring
I have kept the original patch for ESD ("input: goodix: add support
for ESD") since it is still under discussion. I have moved it to the
end of the patch set so it does not block the other changes. Once I have
an answer from DT folks on this I will make the necessary changes for it.
For testing the ACPI changes "ACPI: Translate Linux IRQ number directly
from GpioInt" patchset is needed [1]. This patchset has been merged in
the GPIO tree.
This patches are based on Goodix datasheets for GT911 and GT9271 and
on Goodix driver gt9xx.c for Android (publicly available in Android kernel
trees for various devices). Commit 771d8f1b178e ("Input: goodix - add
device tree support") references a set of public datasheets that can
be used for reference.
