phy: renesas: rzg3e-usb3: Convert to FIELD_MODIFY()

2026-05-10T12:17:45+00:00

Use the FIELD_MODIFY() helper instead of open-coding the same operation. Signed-off-by: Geert Uytterhoeven Reviewed-by: Neil Armstrong Link: https://patch.msgid.link/a52020ba597e2e213b161eee21239f10e6057d9d.1772705690.git.geert+renesas@glider.be Signed-off-by: Vinod Koul

phy: renesas: phy-rzg3e-usb3: Fix malformed MODULE_AUTHOR string

2026-05-10T12:07:53+00:00

Fix a malformed MODULE_AUTHOR macro in the RZ/G3E USB3.0 PHY driver where the author's name and opening angle bracket were missing, leaving only the email address with a stray closing >. Correct it to the standard Name format.

phy: renesas: rcar-gen3-usb2: Simplify ID/VBUS detection logic

2026-05-03T17:05:57+00:00

Read USB2_ADPCTRL once in rcar_gen3_check_id() instead of issuing multiple MMIO reads, and derive both IDDIG and VBUSVALID from the same value. Drop the redundant !! operator, as assigning a masked u32 value to a bool already performs the required normalization. Simplify the logic by comparing the ID and VBUS status directly, which is equivalent to the previous conditional but easier to follow.

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

2026-03-09T12:44:45+00:00

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

2026-01-21T08:46:03+00:00

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

2026-01-21T08:46:02+00:00

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()

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.

This makes it easier to handle different VBUS control register cases and aids future maintenance.
