From aa0e26bb786b00eaa897e024769e299470815efe Mon Sep 17 00:00:00 2001 From: David Rivshin Date: Wed, 29 Mar 2017 00:14:16 -0700 Subject: Input: matrix_keypad - add option to drive inactive columns The gpio-matrix-keypad driver normally sets inactive columns as inputs while scanning. This does not work for all hardware, which may require the inactive columns to be actively driven in order to overcome any pull-ups/downs on the columns.

It also allows us to switch to common way of obtaining GPIO descriptor and away form legacy platform data.
