Revert "Merge patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet""

2024-05-19T14:16:36Z

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay Ethernet"' I failed to notice that b4 noticed it was based on next and so took that as the base commit and merged that part of next to master. This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35. Reported-by: Jonas Karlman Signed-off-by: Tom Rini

usb: dwc3: gadget: Disable GUSB2PHYCFG.SUSPHY for End Transfer

2024-05-16T06:38:24Z

Upstream Linux commit 3aa07f72894d. If there's a disconnection while operating in eSS, there may be a delay in VBUS drop response from the connector. In that case, the internal link state may drop to operate in usb2 speed while the controller thinks the VBUS is still high. The driver must make sure to disable GUSB2PHYCFG.SUSPHY when sending endpoint command while in usb2 speed. The End Transfer command may be called, and only that command needs to go through at this point. Let's keep it simple and unconditionally disable GUSB2PHYCFG.SUSPHY whenever we issue the command. This scenario is not seen in real hardware. In a rare case, our prototype type-c controller/interface may have a slow response triggerring this issue.

usb: dwc3: gadget: properly check ep cmd

2024-05-16T06:38:24Z

Upstream Linux commit 5999914f227b. The cmd argument we pass to dwc3_send_gadget_ep_cmd() could contain extra arguments embedded. When checking for StartTransfer command, we need to make sure to match only lower 4 bits which contain the actual command and ignore the rest.

usb: dwc3: gadget: Check ENBLSLPM before sending ep command

2024-05-16T06:38:24Z

Upstream Linux commit 87dd96111b0b. When operating in USB 2.0 speeds (HS/FS), if GUSB2PHYCFG.ENBLSLPM or GUSB2PHYCFG.SUSPHY is set, it must be cleared before issuing an endpoint command. Current implementation only save and restore GUSB2PHYCFG.SUSPHY configuration. We must save and clear both GUSB2PHYCFG.ENBLSLPM and GUSB2PHYCFG.SUSPHY settings. Restore them after the command is completed.

usb: dwc3: gadget: only resume USB2 PHY in <=HIGHSPEED

2024-05-16T06:38:24Z

Upstream Linux commit ab2a92e7a608. As a micro-power optimization, let's only resume the USB2 PHY if we're working on <=HIGHSPEED. If we're gonna work on SUPERSPEED or SUPERSPEED+, there's no point in resuming the USB2 PHY.

usb: dwc3: gadget: clear SUSPHY bit before ep cmds

2024-05-16T06:38:24Z

Upstream Linux commit 2b0f11df84bb. Synopsys Databook 2.60a has a note that if we're sending an endpoint command we _must_ make sure that DWC3_GUSB2PHY(n).SUSPHY bit is cleared. This patch implements that particular detail.

usb: dwc3: gadget: combine return points into a single one

2024-05-16T06:38:24Z

Upstream Linux commit c0ca324d09a0. dwc3_send_gadget_ep_cmd() had three return points. That becomes a pain to track when we need to debug something or if we need to add more code before returning. Let's combine all three return points into a single one just by introducing a local 'ret' variable.

riscv: add NULL check before calling strlen in the riscv cpu's get_desc()

2024-05-14T10:39:57Z

Without the NULL check, if the devicetree that u-boot loads does not have a compatible property then a store access fault will be raised and force the machine to reset, due to the NULL pointer we passed to strlen. This commit adds this check and will return -ENOSPC to indicate the get_desc failed. Signed-off-by: Hanyuan Zhao Reviewed-by: Leo Yu-Chi Liang
