[PATCH 4.19 057/243] ARM: dts: imx6: RDU2: fix eGalax touchscreen node

From: Greg Kroah-Hartman
Date: Wed Dec 11 2019 - 10:54:13 EST


From: Lucas Stach <l.stach@xxxxxxxxxxxxxx>

[ Upstream commit 749a5068f2e2453a38777b1d5fc322d503cabf1d ]

Use the correct compatible for the new protocol used by the firmware
on the touch controller, the GPIO wakeup isn't used in that case.
Also eGalax touch needs axis swapping, just as with the RMI4 touch.
