Revert "usb: phy: generic: Get the vbus supply"

2024-04-03T13:19:50+00:00

commit fdada0db0b2ae2addef4ccafe50937874dbeeebe upstream. This reverts commit 75fd6485cccef269ac9eb3b71cf56753341195ef. This patch was applied twice by accident, causing probe failures. Revert the accident.

usb: phy: generic: Get the vbus supply

2024-03-26T22:20:57+00:00

[ Upstream commit 75fd6485cccef269ac9eb3b71cf56753341195ef ] While support for working with a vbus was added, the regulator was never actually gotten (despite what was documented). Fix this by actually getting the supply from the device tree.

usb: phy: mxs: remove CONFIG_USB_OTG condition for mxs_phy_is_otg_host()

2024-01-25T23:27:39+00:00

commit ff2b89de471da942a4d853443688113a44fd35ed upstream. When CONFIG_USB_OTG is not set, mxs_phy_is_otg_host() will always return false. This behaviour is wrong. Since phy.last_event will always be set for either host or device mode. Therefore, CONFIG_USB_OTG condition can be removed.

usb: phy: mxs: fix getting wrong state with mxs_phy_is_otg_host()

2023-09-13T07:42:51+00:00

[ Upstream commit 5eda42aebb7668b4dcff025cd3ccb0d3d7c53da6 ] The function mxs_phy_is_otg_host() will return true if OTG_ID_VALUE is 0 at USBPHY_CTRL register. However, OTG_ID_VALUE will not reflect the real state if the ID pin is float, such as Host-only or Type-C cases. The value of OTG_ID_VALUE is always 1 which means device mode. This patch will fix the issue by judging the current mode based on last_event. The controller will update last_event in time.

Pull USB / Thunderbolt updates from Greg KH: "Here is the big set of USB and Thunderbolt driver changes for 6.1-rc1. Nothing major in here, lots of little things with new devices supported and updates for a few drivers. Highlights include: - thunderbolt/USB4 devices supported a bit better than before, and some new ids to enable new hardware devices - USB gadget uvc updates for newer video formats and better v4l integration (the v4l portions were acked by those maintainers) - typec updates for tiny issues and more typec drivers for new chips. - xhci tiny updates for minor issues - big usb-serial ftdi_sio driver update to handle new devices better - lots of tiny dwc3 fixes and updates for the IP block that is showing up everywhere these days - dts updates for new devices being supported - other tiny janitorial and cleanups fixes for lots of different USB drivers. Full details are in the shortlog.

USB: PHY: JZ4770: Switch to use dev_err_probe() helper

2022-09-27T08:37:00+00:00

In the probe path, dev_err() can be replaced with dev_err_probe() which will check if error code is -EPROBE_DEFER and prints the error name. It also sets the defer probe reason which can be checked later through debugfs. It's more simple in error path.

usb: phy: tegra: switch to using devm_gpiod_get()

2022-09-05T11:09:13+00:00

I would like to stop exporting OF-specific devm_gpiod_get_from_of_node() so that gpiolib can be cleaned a bit, so let's switch to the generic device property API. I believe that the only reason the driver, instead of the standard devm_gpiod_get(), used devm_gpiod_get_from_of_node() is because it wanted to set up a pretty consumer name for the GPIO, and we now have a special API for that.
