From 1fabeeb799abca1d4fb5ba541410ba847cdc20d9 Mon Sep 17 00:00:00 2001 From: Lech Perczak Date: Sat, 14 May 2022 14:50:02 +0200 Subject: [PATCH] ath79: ZTE MF286[A,R]: add "Power button blocker" GPIO switch ZTE MF286A and MF286R feature a "power switch override" GPIO in stock firmware as means to prevent power interruption during firmware update, especially when used with internal battery. To ensure that this GPIO is properly driven as in stock firmware, configure it with userspace GPIO switch. It was observed that on some units, the modem would not be restarted together with the board itself on reboot, this should help with that as well.
