This series adds the support of multiple regulators. This is the second version of the series. The previous version depended of a patch set for the regulator framework which was not accepted. Then I needed to do this in a different way that it was done for the PHY. As result the regulator need to be associated to each port as the host node level using the property target-port-supply, where is the port number. But it is however mandatory to have one port sub-node for each port associated to a regulator. Since the 1st version I also took into account the comments from Hans and added a patch to use the new binding for the device tree of the Armada 38x GP. This last patch should be merged through the mvebu tree. Thanks, Grégory Changelog: v1 -> v2: - Kept the case when no child node are present under the ahci node - Fix the test done under the label disable_target_pwrs - No more use an of_ version of the regulator framework and instead associate each regulator of a port with an unique name. - Added the acked-by on the clean-up patch Gregory CLEMENT (4): ata: libahci: Clean-up the ahci_platform_en/disable_phys functions Documentation: bindings: Add the regulator property to the sub-nodes AHCI bindings ata: libahci: Allow using multiple regulators ARM: mvebu: Armada 385 GP: Add regulators to the SATA port .../devicetree/bindings/ata/ahci-platform.txt | 9 +- arch/arm/boot/dts/armada-388-gp.dts | 126 ++++++++++++ drivers/ata/ahci.h | 2 +- drivers/ata/ahci_imx.c | 14 +- drivers/ata/libahci_platform.c | 224 ++++++++++++++------- include/linux/ahci_platform.h | 2 + 6 files changed, 294 insertions(+), 83 deletions(-) -- 1.9.1
