charset="us-ascii" Content-Transfer-Encoding: 7bit Sender: "linux-phy" Errors-To: linux-phy-bounces+linux-phy=archiver.kernel.org@lists.infradead.org Tested this revision on IPQ5018 hardware - a TP-Link Archer AX55 v1, backported onto 6.18.44. Both radios on this board are on AHB and PCIe is unused, so nothing else contends for the SS PHY; the combo driver is exercised purely on its USB3 side here. Two USB 3.2 gen 1 sticks, all enumerating SuperSpeed (speed=5000, version=3.20, 5000M in lsusb -t): - hot-plug, both sticks; - warm reboot with the stick inserted - SuperSpeed 0.8 s after xHCI registers; - cold power-on with the stick inserted - same, no fall back to 480M; - 130 MB/s sustained over a 3 GB raw read, unchanged from the previous revision on the same stick; - no USB or xHCI error in dmesg across the whole run. I also exercised the vdd-supply path that patch 12 adds to the RDP432-C2, since enable/disable sits in phy_init/phy_shutdown and that is the code this revision rewrites: unbinding dwc3-qcom drops the port's 5 V rail and the device disappears, re-binding brings it back at SuperSpeed 1.8 s later. Works on this board too. I do not have an IPQ5332, so the combo PHY's PCIe side and the 5332 instance are untested by me.
