From 10340f8d7b6dd54e616339c8ccb2f397133ebea0 Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Fri, 29 Jan 2021 10:28:45 -0800 Subject: ata: ahci_brcm: Add back regulators management While reworking the resources management and departing from using ahci_platform_enable_resources() which did not allow a proper step separation like we need, we unfortunately lost the ability to control AHCI regulators. This broke some Broadcom STB systems that do expect regulators to be turned on to link up with attached hard drives.
