c8c5d5e89a phy: qcom-qmp-usb: drop pipe clock lane suffix 
The pipe clock is defined in the "lane" node so there's no need to keep
adding a redundant lane-number suffix to the clock name.

Update driver to support the new binding where the pipe clock name has
been deprecated by instead requesting the clock by index.

712e5dffe9 phy: qcom-qmp-combo: Parameterize swing and pre_emphasis tables 
The swing and pre-emphasis tables differ between different PHY versions,
or perhaps between different platforms. In particular in order to
introduce SC8280XP these tables needs to be replaced.

Make it possible to specify these tables per PHY config.

533e13305c phy: tegra: xusb: Only warn once about reset problems in .remove() 
The single difference between returning 0 and returning an error code in
a platform remove callback is that in the latter case the platform core
emits a warning about the error being ignored.

If reset_control_assert() fails there is already a warning, so suppress
the more generic (and less helpful) by returning 0 in
tegra_xusb_padctl_remove().

This is a preparation for making platform remove callbacks return void.

The eDP phy can be used to drive either eDP or DP output, with some
minor variations in some of the configuration and seemingly a need for
implementing swing and pre_emphasis calibration.

Introduce a config object, indicating if the phy is operating in eDP or
DP mode and swing/pre-emphasis calibration to support this.

For J7200-SR2.0 and AM64 we don't model Common refclock divider as
a clock divider as the divisor rate is fixed based on operating
reference clock frequency. We just program the recommended value
into the register. This simplifies the device tree and implementation
a lot.
