Subject: [PATCH] Input: stmpe: Add axis inversion and swapping capability
Date: Tue, 22 Sep 2020 11:39:03 +0200 [thread overview]
Message-ID: <20200922093903.157232-1-s.riedmueller@phytec.de> (raw)
Make use of generic touchscreen_properties structure to add axis
inversion and swapping capabilities. It's configurable via devicetree
properties:
touchscreen-inverted-x
touchscreen-inverted-y
touchscreen-swapped-x-y
