usb: ehci-mx6: Enable OTG detection on imx8mm and imx8mn

2022-02-10T23:03:48Z

The imx8mm and imx8mn appear compatible with imx7d-usb flags in the OTG driver. If the dr_mode is defined as host or peripheral, the device appears to operate correctly, however the auto host/peripheral detection results in an error. The solution isn't just adding checks for imx8mm and imx8mn to the check for imx7, because the USB clock needs to be running to read from the USBNC_PHY_STATUS_OFFSET register or it will hang. Marek requested that I not enable the clocks in ehci_usb_of_to_plat, so I modified that function to return an unknown state if the device tree does not explicitly state whether it is a host or a peripheral. When the driver probes, it looks to see if it's in the unknown state, and only then will it read the register to auto-detect. Signed-off-by: Adam Ford Tested-by: Tim Harvey

usb: ehci: dm: Convert i.MX28 ehci code to driver model

2022-01-26T22:22:59Z

This commit converts i.MX28's EHCI USB host driver to driver model (DM_USB). It is a straightforward conversion (to reuse as much code as possible), based on ehci-mx5.c code. Signed-off-by: Lukasz Majewski

usb: ehci: Move common mxs code to separate functions (ehci_hcd_{stop|start})

2022-01-26T22:22:59Z

Those functions will be re-used when the ehci MXS driver (for imx28) will be converted to also support CONFIG_DM_USB. No functional changes introduced - only cosmetic changes (u32 type) and alignment to pass checkpatch. Signed-off-by: Lukasz Majewski

usb: ehci: Refactor the ehci_mxs_toggle_clock function to be reused with DM

2022-01-26T22:22:59Z

This function is going to be reused with the CONFIG_DM_USB enabled in the imx28 mxs USB ehci driver. No functional changes introduced. Signed-off-by: Lukasz Majewski

usb: Modify Kconfig of the USB_EHCI_MXS to use this driver with imx28

2022-01-26T22:22:59Z

The ehci-mxs driver can be also used with imx28 SoC, not only imx23. Signed-off-by: Lukasz Majewski

usb: Use the first available device for ehci_gadget

2022-01-25T18:47:07Z

For whatever reason, usb_setup_ehci_gadget removes and probes USB device 0. However, not all systems have a device 0. Use the first device instead. The device probed should probably have something to do with the controller (as specified by e.g. ums or fastboot ). In fact, I find it odd that we probe the USB device in the first place, because this is just to set up the gadget itself. Presumably, the controller should be probed by usb_gadget_initialize somehow.

usb: xhci: fsl: add new compatible fsl,ls1028a-dwc3

2021-11-09T11:48:23Z

The official ls1028a binding of the driver uses the following as compatibles: compatible = "fsl,ls1028a-dwc3", "snps,dwc3"; Change the ls1028a device tree and add this new compatible to the fsl specific xhci driver, otherwise the generic dwc3 driver will be used with the compatibles above.
