From f7dbdcfa54adf474880be2e90e772f93fadae3b7 Mon Sep 17 00:00:00 2001 From: Daniel Golle Date: Fri, 9 Sep 2022 20:44:46 +0100 Subject: mediatek: filogic: use WPS button instead of RST on BPi-R3 The GPIO used for the RST button is also used for PCIe-CLKREQ signal. Hence it cannot be used as button signal if PCIe is also used. Wire up WPS button to serve as KEY_RESTART in Linux and "reset" button in U-Boot.
