From da45adf97f57a561fc290e7cdd3a3dcb184cc88e Mon Sep 17 00:00:00 2001 From: Philipp Zabel Date: Wed, 19 Jul 2017 17:25:05 +0200 Subject: ARM: rockchip: explicitly request exclusive reset control in smp code Commit a53e35db70d1 ("reset: Ensure drivers are explicit when requesting reset lines") started to transition the reset control request API calls to explicitly state whether the driver needs exclusive or shared reset control behavior. Convert all drivers requesting exclusive resets to the explicit API call so the temporary transition helpers can be removed. No functional changes.
