phy: renesas: rcar-gen3-usb2: Add suspend/resume support

2025-11-20T16:44:42+00:00

The Renesas RZ/G3S supports a power saving mode where power to most of the SoC components is turned off. The USB PHY is among these components. Because of this the settings applied in driver probe need to be executed also on resume path. On suspend path only reset signal need to be asserted. Add suspend/resume support.

phy: renesas: rcar-gen3-usb2: Move phy_data->init_bus check

2025-11-20T16:44:42+00:00

Move the check of phy_data->init_bus from rcar_gen3_phy_usb2_init_bus() to rcar_gen3_phy_usb2_probe() to avoid having it duplicated in both the probe path and the upcoming resume code. This is a preparatory patch.

phy: renesas: rcar-gen3-usb2: Fix an error handling path in rcar_gen3_phy_usb2_probe()

2025-11-20T16:44:28+00:00

If an error occurs after the reset_control_deassert(), reset_control_assert() must be called, as already done in the remove function. Use devm_add_action_or_reset() to add the missing call and simplify the .remove() function accordingly. While at it, drop struct rcar_gen3_chan::rstc as it is not used aymore.

phy: renesas: rcar-gen3-usb2: Fix ID check logic with VBUS valid

2025-09-01T16:45:56+00:00

The existing ID detection logic returned false when both IDDIG and VBUSVALID were set, which caused incorrect role determination in some cases. The condition: !(device && !vbus_valid) did not properly reflect the intended relationship between IDDIG and VBUSVALID signals. Update the logic to: return vbus_valid ? device : !device; This ensures that when VBUS is valid, the role follows the IDDIG value, and when VBUS is not valid, the role is inverted, matching the expected OTG behavior.

Relocate the debug print in rcar_gen3_enable_vbus_ctrl() to appear after the `val` variable is assigned and updated based on the VBUS state. This ensures that the debug log reflects the actual register value being written, improving debugging accuracy.
