phy: renesas: rcar-gen3-usb2: drop helper getting optional mux-state

2026-03-09T12:44:45Z

Multiplexer subsystem has now added helpers for getting managed optional mux-state. Switch to the new devm_mux_state_get_optional_selected helper. This change is only compile-tested. Signed-off-by: Josua Mayer Acked-by: Vinod Koul Reviewed-by: Wolfram Sang Signed-off-by: Ulf Hansson

phy: renesas: rcar-gen3-usb2: Use mux-state for phyrst management

2026-01-21T08:46:03Z

Add support for selecting the phyrst mux-state using the Linux mux subsystem in the R-Car Gen3 USB2 PHY driver. This ensures correct hardware initialization and integration with systems utilizing the mux-state device tree property. A temporary wrapper for optional muxes is introduced until native support is available in the multiplexer subsystem.

phy: renesas: rcar-gen3-usb2: Add regulator for OTG VBUS control

2026-01-21T08:46:02Z

Enable OTG VBUS control on R-Car Gen3 USB2 PHY by registering a regulator driver that manages the VBOUT line. This change allows the controller to handle VBUS output for OTG ports using the regulator framework when the platform requires hardware-based VBUS control. Without this, some platforms cannot properly manage VBUS power on OTG- capable ports, leading to potential USB functionality issues.

phy: renesas: rcar-gen3-usb2: Use devm_pm_runtime_enable()

2026-01-21T08:46:02Z

Replace pm_runtime_enable() with devm_pm_runtime_enable() to ensure proper cleanup if the probe fails. This change enhances driver reliability by avoiding resource leaks, as the devm-managed version automatically handles disabling at probe failure or device removal.
