2021-07-14phy: Add driver for ST-Ericsson AB8500 USB PHYStephan Gerhold
The AB8500 PMIC contains an USB PHY that needs to be set up in device or host mode to make USB work properly. Add a simple driver for the generic PHY uclass that allows enabling it. The if (CONFIG_IS_ENABLED(USB_MUSB_HOST)) might be a bit strange. The USB PHY must be configured in either host or device mode and somehow the USB PHY driver must be made aware of the mode. Actually, the MUSB driver used together with this PHY does not support dynamic selection of host/device mode in U-Boot at the moment. Therefore, one very simple approach that works fine is to select the mode to configure at compile time. When the MUSB driver is configured in host mode the PHY is configured in host mode, and similarly when the MUSB driver is configured in device/gadget mode.

2021-07-10phy: sun4i-usb: Fix PHY0 routing and passby configuration for MUSBPaul Kocialkowski
Recent Allwinner platforms (starting with the H3) only use the MUSB controller for peripheral mode and use HCI for host mode. As a result, extra steps need to be taken to properly route USB signals to one or the other. More precisely, the following is required: * Routing the pins to either HCI/MUSB (controlled by PHY); * Enabling USB PHY passby in HCI mode (controlled by PMU). The current code will enable passby for each PHY and reroute PHY0 to MUSB, which is inconsistent and results in broken USB peripheral support. Passby on PHY0 must only be enabled when we want to use HCI. Since host/device mode detection is not available from the PHY code and because U-Boot does not support changing the mode dynamically anyway, we can just mux the controller to MUSB if it is enabled and mux it to HCI otherwise. This fixes USB peripheral support for platforms with PHY0 dual-route, especially H3/H5 and V3s.

2021-04-29phy: marvell: fix pll initialization for second utmi portGrzegorz Jaszczyk
According to Design Reference Specification the PHY PLL and Calibration register from PHY0 are shared for multi-port PHY. PLL control registers inside other PHY channels are not used. This commit reworks utmi device tree nodes in a way that common PHY PLL registers are moved to main utmi node. Accordingly both child nodes utmi-unit range is reduced and register offsets in utmi_phy.h are updated to this change. This fixes issues in scenarios when only utmi port1 was in use, which resulted with lack of correct pll initialization.
