2020-11-30phy: samsung: Add support for the Exynos5420 variant of the USB2 PHYMarek Szyprowski
Exynos5420 differs a bit from Exynos5250 in USB2 PHY related registers in the PMU region. Add a variant for the Exynos5420 case. Till now, USB2 PHY worked only because the bootloader enabled the PHY, but then driver messed USB 3.0 DRD related registers during the suspend/resume cycle.

2020-11-20phy: amlogic: phy-meson-axg-mipi-pcie-analog: add support for MIPI DSI analogNeil Armstrong
The AXG Analog MIPI-DSI PHY also provides functions to the PCIe PHY, thus we need to have inclusive support for both interfaces at runtime. This fixes the regmap get from parent node, removes cell param to select a mode and implement runtime configuration & power on/off for both functions since they are not exclusive.

2020-11-19phy: phy-bcm-ns-usb3: drop support for deprecated DT bindingRafał Miłecki
Initially this PHY driver was implementing MDIO access on its own. It was caused by lack of proper hardware design understanding. It has been changed back in 2017. DT bindings were changed and driver was updated to use MDIO layer. It should be really safe now to drop the old deprecated code. All Linux stored DT files don't use it for 3,5 year. There is close to 0 chance there is any bootloader with its own DTB using old the binding.

If, for some reason, the xusb PHY fails to probe, it leaves a dangling pointer attached to the platform device structure. This would normally be harmless, but the Tegra XHCI driver then goes and extract that pointer from the PHY device.

2020-10-28phy: usb: Fix incorrect clearing of tca_drv_sel bit in SETUP reg for 7211Al Cooper
The 7211a0 has a tca_drv_sel bit in the USB SETUP register that should never be enabled. This feature is only used if there is a USB Type-C PHY, and the 7211 does not have one. If the bit is enabled, the VBUS signal will never be asserted. In the 7211a0, the bit was incorrectly defaulted to on so the driver had to clear the bit. In the 7211c0 the state was inverted so the driver should no longer clear the bit. This hasn't been a problem because all current 7211 boards don't use the VBUS signal, but there are some future customer boards that may use it.

Driver ->power_on and ->power_off callbacks leaks internal SMCC firmware return codes to phy caller. This patch converts SMCC error codes to standard linux errno codes. Include file linux/arm-smccc.h already provides defines for SMCC error codes, so use them instead of custom driver defines. Note that return value is signed 32bit, but stored in unsigned long type with zero padding.
