From 50fd31fd7781e979254af49efcbc1fbb4882a751 Mon Sep 17 00:00:00 2001 From: Patrick Delaunay Date: Thu, 18 Apr 2019 17:16:21 +0200 Subject: [PATCH] sysreset: syscon: remove POWER reset cause The sysreset of 'POWER' type is a PMIC reset defined as 'remove and restore power'. So normally only COLD/WARN is supported by sysreset_syscon. This modification allows to use the function sysreset_walk(SYSRESET_POWER) when it is supported by PMIC driver (see example in stpmic1).
