Message-Id: <20211024145931.1916-2-dariobin@libero.it> Date: Sun, 24 Oct 2021 16:59:25 +0200 From: Dario Binacchi <dariobin@...ero.it> To: linux-kernel@...r.kernel.org Cc: Dario Binacchi <dariobin@...ero.it>, Dmitry Torokhov <dmitry.torokhov@...il.com>, Rachna Patil <rachna@...com>, linux-input@...r.kernel.org Subject: [PATCH 1/6] input: ti_am335x_tsc: set ADCREFM for X configuration As reported by the STEPCONFIG[1-16] registered field descriptions of the TI reference manual, for the ADC "in single ended, SEL_INM_SWC_3_0 must be 1xxx". Unlike the Y and Z coordinates, this bit has not been set for the step configuration registers used to sample the X coordinate.
