usb: dwc2: drd: fix clock gating on USB role switch

2024-10-04T14:33:33+00:00

commit 2c6b6afa59e78bebcb65bbc8a76b3459f139547c upstream. The dwc2_handle_usb_suspend_intr() function disables gadget clocks in USB peripheral mode when no other power-down mode is available (introduced by commit 0112b7ce68ea ("usb: dwc2: Update dwc2_handle_usb_suspend_intr function.")). However, the dwc2_drd_role_sw_set() USB role update handler attempts to read DWC2 registers if the USB role has changed while the USB is in suspend mode (when the clocks are gated). This causes the system to hang. Release the gadget clocks before handling the USB role update. Fixes: 0112b7ce68ea ("usb: dwc2: Update dwc2_handle_usb_suspend_intr function.")
