2020-07-28phy: usbphyc: use regulator_set_enable_if_allowed for disabling vdd supplyPatrick Delaunay
Use regulator_set_enable_if_allowed() api instead of regulator_set_enable() while disabling vdd supply. This way the driver doesn't see an error when disabling an always-on regulator. This patch is needed since the commit f93fab312615 ("Revert 'power: regulator: Return success on attempt to disable an always-on regulator'") and use the API introduced by commit cc4a224af226 ("power: regulator: Introduce regulator_set_enable_if_allowed api").

2020-02-05dm: core: Create a new header file for 'compat' featuresSimon Glass
At present dm/device.h includes the linux-compatible features. This requires including linux/compat.h which in turn includes a lot of headers. One of these is malloc.h which we thus end up including in every file in U-Boot. Apart from the inefficiency of this, it is problematic for sandbox which needs to use the system malloc() in some files. Move the compatibility features into a separate header file.

2019-04-12phy: Add USB PHY driver for the MT76x8 (7628/7688) SoCStefan Roese
This driver is derived from this Linux driver: linux/drivers/phy/ralink/phy-ralink-usb.c The driver sets up power and host mode, but also needs to configure PHY registers for the MT7628 and MT7688. I removed the reset controller handling for the USB host and device, as it does not seem to be necessary right now. The soft reset bits for both devices are enabled by default and testing has shown (with hackish reset handling added), that USB related commands work identical with or without the reset handling. Please note that the resulting USB support is tested only very minimal. I was able to detect one of my 3 currently available USB sticks.
