Subject: [PATCH] ARM: dts: ccimx6ulsbcpro: Configure touch GPIO reset line
|
|
|
|
The Goodix touch requires both the INT and reset lines in order to fix
|
|
an I2C address at startup.
|
|
|
|
This commit uses the IOEXP GPIO29 to control the DISP_5V supply which
|
|
controls the voltage source for the reset line pull-up. It also sets the
|
|
internal pull-up on the INT line so the line is not left floating.
|
|
|
|
Upstream-Status: Inappropriate [digi specific]
