Hi, The current implementation of the libahci allows using one PHY per port but we still have one single regulator for the whole controller. This series 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). While I was working on it I also did a small clean-up, it is the purpose of the 1st patch. The main patch of the series (the 3rd one) also depends of a patch of the regulator framework that I submitted yesterday: "regulator: core: Add the device tree version to the regulator_get family", https://lkml.org/lkml/2014/12/26/155 I refactored the PHY support in the same time, so I would like to have a feedback from the Berlin platform to ensure that no regressions was introduced. Thanks, Grégory Gregory CLEMENT (3): 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 to use multiple regulators .../devicetree/bindings/ata/ahci-platform.txt | 3 +- drivers/ata/ahci.h | 2 +- drivers/ata/ahci_imx.c | 14 +- drivers/ata/libahci_platform.c | 212 ++++++++++++++------- include/linux/ahci_platform.h | 2 + 5 files changed, 153 insertions(+), 80 deletions(-) -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
