In order to support the Amlogic GXL/GXM SoCs, the reset line must be handled as shared since also used by the PHYs. Reviewed-by: Martin Blumenstingl <martin.blumenstingl@googlemail.com> Signed-off-by: Neil Armstrong <narmstrong@baylibre.com> Signed-off-by: Felipe Balbi <balbi@kernel.org>

Neil Armstrong authored
On the Amlogic GXL/GXM SoCs, only the USB control registers are available, the PHY mode being handled in the PHY registers. Thus, handle the PHY mode registers in separate regmaps and prepare support for Amlogic GXL/GXM SoCs by moving the regmap setup in a callback set in the SoC match data.

dt-bindings: usb: amlogic,meson-g12a-usb-ctrl: add the Amlogic GXL and GXM Families USB Glue Bindings The Amlogic GXL and GXM is slightly different from the Amlogic G12A Glue. The GXL SoCs only embeds 2 USB2 PHYs and no USB3 PHYs, and the GXM SoCs embeds 3 USB2 PHYs.

The flow from function dwc3_gadget_ep_dequeue() is not easy to follow. Refactor it for easier read. No functional change in this commit. Signed-off-by: Thinh Nguyen <thinhn@synopsys.com> Signed-off-by: Felipe Balbi <balbi@kernel.org>

Thinh Nguyen authored
Remove 2 unnecessary checks: 1) A request in the started_list must have its trb field set. So checking for req->trb is unnecessary. 2) An endpoint must have started (and have not ended) for the request to still be in the started_list. There's no point to check if the endpoint is started. We had this check because previously the driver didn't handle the endpoint's started/ended flags for END_TRANSFER command properly. See commit 9f45581f ("usb: dwc3: gadget: early giveback if End Transfer already completed"). Signed-off-by: Thinh Nguyen <thinhn@synopsys.com> Signed-off-by: Felipe Balbi <balbi@kernel.org>

Thinh Nguyen authored
If a request is dequeued, the transfer is cancelled. Give back all the started requests. In most scenarios, the function driver dequeues all requests of a transfer when there's a failure. If the function driver follows this, then it's fine. If not, then we'd be skipping TRBs at different points within the dequeue and enqueue pointers, making dequeue/enqueue pointers useless. To enforce and make sure that we're properly skipping TRBs, cancel all the started requests and give back all the cancelled requests to the function drivers.

DWC3 must not issue CLEAR_STALL command to control endpoints. The controller automatically clears the STALL when it receives the SETUP token. Also, when the driver receives ClearFeature(halt_ep), DWC3 must stop any active transfer from the endpoint and give back all the requests to the function drivers.

The DRD module calls dwc3_set_mode() on role switches, i.e. when a device is being plugged in. In order to support continuous runtime power management when plugging in / unplugging a cable, we need to call pm_runtime_get_sync() in this path.
