From d33dbddf43a055f69bda7f3488bb1e136d1b6bbc Mon Sep 17 00:00:00 2001 From: Andrew Davis Date: Wed, 26 Jul 2023 11:04:41 -0500 Subject: [PATCH] ARM: keystone: Merge PM function into main support file The one function left in this file does not justify a whole extra file nor the keystone.h support file used to forward declare that function. Merge this into the main keystone.c file.
