From c7d7ddee7e24eedde6149eefbcfbfbc7125b9ff0 Mon Sep 17 00:00:00 2001 From: Gregory CLEMENT Date: Thu, 15 Jan 2015 15:09:37 +0100 Subject: ata: libahci: Allow using multiple regulators The current implementation of the libahci allows using multiple PHYs but not multiple regulators. This patch adds the support of multiple regulators. Until now it was mandatory to have a PHY under a subnode, now a port subnode can contain either a regulator or a PHY (or both). In order to be able to asociate a port with a regulator the port are now a platform device in the device tree case. There was only one driver which used directly the regulator field of the ahci_host_priv structure. To preserve the bisectability the change in the ahci_imx driver was done in the same patch.
