The USB/DP combo PHY exposes the "qmp_dp_phy_pll_link_clk" and "qmp_dp_phy_pll_vco_div_clk" clocks, that are consumed by the display clock controller. But for boards with multiple enabled QMP USB/DP combo instances the hard coded names collides - and hence only the first probed device is allowed to register. Given that clocks are no longer reference globally by name and it's possible to replace the hard coded names by something unique, but still user friendly. The two new clock names are based on dev_name() and results in names such as "88ee000.phy::link_clk" and "88ee000.phy::vco_div_clk".

devm_phy_create can return -EPROBE_DEFER if the vbus-supply is not ready yet. Silence this warning as the driver framework will re-attempt registering the PHY. Use dev_err_probe() for phy resources to indicate the deferral reason when waiting for the resource to come up.

Since commit 88d26136 ("PM: Prevent runtime suspend during system resume"), PM runtime will not let devices idle during system suspend. This is because of the pm_runtime_get_noresume() call done in device_prepare() that is not released until at device_complete() after resume. We must now disable the USB PHY in suspend if no USB cable is connected.

Due to the FreqMeter bank is not used but reserved, it's backward with v2 until now. For mt8195, no function changes when use generic v2 or v3 compatible, but prefer to use v3's compatible, it will not waste the time to calibrate the slew rate, and also correspond with hardware version.
