2021-10-26phy: stm32: restore utmi switch on resumeAmelie Delaunay
UTMI switch value can be lost during suspend/resume, depending on the power state reached. This patch adds resume function to usbphyc, to reconfigure utmi switch after suspend.

2021-08-20phy: qmp: Provide unique clock names for DP clocksBjorn Andersson
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".

Add PHY input reference clock frequency as a new dimension to select proper register configuration. No functional change is intended.

This patch adds USB2.0 PHY support for RZ/G2L SoC. We need to use a different compatible string due to some differences with R-Car Gen3 USB2.0 PHY. It uses line ctrl register for OTG_ID pin changes and different OTG-BC interrupt bit for device recognition.

2021-08-06phy: phy-twl4030-usb: Disable PHY for suspendTony Lindgren
Since commit 88d26136a256 ("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.

The controller is designed to use use PLL integer mode, but in fact used fractional mode for some ones on mt8195, this causes signal degradation (e.g. eye diagram test fail), fix it by switching PLL to 26Mhz from default 48Mhz to improve signal quality.
