From a1b70a44b80af641a441937803cb8251e8e6d8e3 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Thu, 8 Aug 2019 11:03:59 -0700 Subject: Input: bu21013_ts - convert to use GPIO descriptors This driver can use GPIO descriptors rather than GPIO numbers without any problems, convert it. Name the field variables after the actual pins on the chip rather than the "reset" and "touch" names from the devicetree bindings that are vaguely inaccurate. No in-tree users pass GPIO numbers in platform data so drop this. Descriptor tables can be used to get these GPIOs from a board file if need be.
