From a114cbd00afe7afa3a6403fb025632ba6b47b443 Mon Sep 17 00:00:00 2001 From: Daniel Mack Date: Wed, 4 Jul 2018 15:46:22 +0000 Subject: [PATCH] Input: eeti - drop module parameters, parse DT properties The only user of this driver in mainline does not make use of the module parameters, so let's remove them. All properties for this driver should be set through DT or pdata. Use touchscreen_parse_properties() to automatically set some of the common touchscreen properties and derive the axis inversion through that. And finally, use touchscreen_report_pos() to handle the DT properties automatically instead of doing the inversion ourselves.
