Hi, On DRA7-evm, the VDDA_1V8_PHY supply must be always-on for proper functioning of the PHYs on the SoC.
The 3.3V USB supply (ldousb_reg) can be turned OFF when the High Speed USB PHYs are not in use. We add regulator support in the PHY framework core to manage the PHY's regulator during PHY power on/off. Finally we add the 3.3V regulator information to the USB2 PHYs. This series should get the USB and SATA working again on 3.16 on DRA7-evm. cheers, -roger --- Roger Quadros (6): ARM: dts: dra7-evm: Make VDDA_1V8_PHY supply always on phy: core: Fix error path in phy_create() phy: core: Support regulator supply for PHY power phy: core: Add phy-supply to DT binding documentation phy: omap-usb2: Balance pm_runtime_enable() on probe failure ARM: dts: dra7-evm: Add regulator information to USB2 PHYs .../devicetree/bindings/phy/phy-bindings.txt | 4 +++ arch/arm/boot/dts/dra7-evm.dts | 9 +++++ drivers/phy/phy-core.c | 39 ++++++++++++++++++++-- drivers/phy/phy-omap-usb2.c | 8 +++-- include/linux/phy/phy.h | 2 ++ 5 files changed, 57 insertions(+), 5 deletions(-) -- 1.8.3.2 -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
