Similar to commit 17db82300f80 ("MLK-25089 phy: freescale: pcie: fix the
imx8mp evk ep rc link speed issue")
Fine tune the PHY parameters, let the PCIe link up to GEN3 between two
i.MX865 EVK boards in the i.MX EP RC validation system.Since this fine tuned is only specified for EVK boards. Add the command
parameter to specify it when do the EP RC tests between two i.MX8MP EVK
boards. Use the "pcie_phy_tuned=yes" to enable the PHY fine-tune.Signed-off-by: Richard Zhu

[ Upstream commit b097efba9580d1f7cbc80cda84e768983e3de541 ]
Currently there is a null pointer check for hdmi_phy that implies it
may be null, however a dev_err messages dereferences this potential null
pointer. Avoid a null pointer dereference by only emitting the dev_err
message if hdmi_phy is non-null. It is a moot point if the error message
needs to be printed at all, but since this is a relatively new piece of
code it may be useful to keep the message in for the moment in case there
are unforseen errors that need to be reported.Fixes: be28b6507c46 ("drm/mediatek: separate hdmi phy to different file")

In commit "phy: tegra: xusb: Add usb-phy support", an OTG capable PHY
device, such as phy-usb2.0 device of Jetson-TX1 platform, will be
bound to the tegra-xusb-padctl driver by the following line in
tegra_xusb_setup_usb_role_switch().port->usb_phy.dev->driver = port->padctl->dev->driver;
With this, dev_pm_ops set of tegra-xusb-padctl driver will be invoked
for the OTG capable PHY incorrectly as below logs show.This commit fixes the issue by assigning an empty driver to it.

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.Signed-off-by: Al Cooper
