From f0f56716fc3e5d547fd7811eb218a30ed0695605 Mon Sep 17 00:00:00 2001 From: Kunihiko Hayashi Date: Fri, 23 Mar 2018 10:30:53 +0900 Subject: ata: ahci-platform: add reset control support Add support to get and control a list of resets for the device as optional and shared. These resets must be kept de-asserted until the device is enabled. This is specified as shared because some SoCs like UniPhier series have common reset controls with all ahci controller instances.
