From 7ff213193310ef8d0ee5f04f79d791210787ac2c Mon Sep 17 00:00:00 2001 From: Niklas Söderlund Date: Thu, 11 Apr 2019 00:22:40 +0200 Subject: mmc: tmio: move runtime PM enablement to the driver implementations MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Both the Renesas and Uniphier implementations perform actions which affect runtime PM before calling into the core tmio_mmc_host_probe() which enabled runtime PM. Move pm_runtime_enable() from the core and tmio_mmc_host_probe() into each drivers probe() so it can be called before any clocks or other resources are switched on.
