Merge tag 'phy-for-4.17' of git://git.kernel.org/pub/scm/linux/kernel/git/kishon/linux-phy into usb-next
Kishon writes: phy: for 4.17 *) Add USB PHY driver for MDM6600 on Droid *) Add USB PHY driver for STM32 USB PHY Controller *) Add inno-usb2-phy driver for hi3798cv200 SoC *) Add combo phy driver (SATA/USB/PCIE) for HiSilicon STB SoCs *) Add USB3 PHY driver for Meson GXL and GXM *) Add support for R8A77965 Gen3 USB 2.0 PHY in phy-rcar-gen3-usb2 driver *) Add support for qualcomm QUSB2 V2 and QMP V3 USB3 PHY in phy-qcom-qusb2 and phy-qcom-qmp PHY driver respectively *) Add support for runtime PM in phy-qcom-qusb2 and phy-qcom-qmp PHY drivers *) Add support for Allwinner R40 USB PHY in sun4i-usb PHY driver *) Add support in rockchip-typec PHY driver to make extcon optional and fallback to working in host mode if extcon is missing *) Add support in rockchip-typec PHY driver to mux PHYs connected to DP *) Add support to configure slew rate parameters in phy-mtk-tphy PHY driver *) Add workaround for missing Vbus det interrupts on Allwinner A23/A33 *) Add USB speed related PHY modes in phy core *) Fix PHY 'structure' documentation *) Force rockchip-typec PHY to USB2 if DP-only mode is used *) Fix phy-qcom-qusb2 and phy-qcom-qmp PHY drivers to follow PHY reset and initialization sequence as per hardware programming manual *) Fix Marvell BG2CD SoC USB failure in phy-berlin-usb driver *) Minor fixes in lpc18xx-usb-otg, xusb-tegra210 and phy-rockchip-emmc PHY drivers Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com>
