Kishon writes:
phy: for 5.1
*) Add a new driver to support Armada 3700 COMPHY IP (supports SATA, USB3,
PCIe)
*) Add a new driver to support Armada UTMI PHY
*) Add a new driver to support Cadence D-PHY
*) Extend omap-usb2 PHY driver to be used for AM654 USB2 PHY
*) Extend qcom-qmp PHY driver to be used for UFS PHY and USB3 PHY in Qualcomm
MSM8998
*) Extend qcom-qusb2 PHY driver to support QUSB2 PHY in Qualcomm MSM8998
*) Remove module specific code that is present for drivers that can be only
built-in
*) Allow Freescale IMX8MQ USB to be used for multiple SoCs and not just
i.MX8MQ
*) Cleanups such as switch to SPDX identifier, use readl_poll_timeout macro,
remove unused headers etc.,
