* spi: spi-uclass: Add new spi_get_bus_and_cs() implementationPatrice Chotard2022-05-231-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Move legacy spi_get_bus_and_cs() code to _spi_get_bus_and_cs(). Add new spi_get_bus_and_cs() implementation which rely on DT for speed and mode and don't need any drv_name nor dev_name parameters. This will prepare the ground for next patch. Update all callers to use _spi_get_bus_and_cs() to keep the same behavior.

* usb: xhci-dwc3: Support role switch default roleMark Kettenis2022-05-202-0/+22
| | | | | | | | | | | | | | When the device tree indicates support for role switching through the "usb-role-switch" property, take the "role-switch-default-mode" property into account when deciding which role to put the controller into. This makes USB devices work on Apple M1 systems where the device tree may include a "dr_mode" property that is set to "otg", but where we need to put the controller into "host" mode to see devices connected to the type-C ports.

* usb: ehci-mx6: Enable OTG detection on imx8mm and imx8mnAdam Ford2022-02-111-5/+18
| | | | | | | | | | | | | | | | | | | | | | 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.

* dfu: handle short frame result of UPLOAD in state_dfu_idlePatrick Delaunay2022-01-281-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In DFU v1.1 specification [1] the DFU_UPLOAD (Short Frame) is handled only in dfuUPLOADIDLE state: - Figure A.1 Interface state transition diagram - the state description in chapter A.2 A.2.3 State 2 dfuIDLE on Receipt of the DFU_UPLOAD request,and bitCanUpload = 1 the Next State is dfuUPLOADIDLE A.2.10 State 9 dfuUPLOAD-IDLE When the length of the data transferred by the device in response to a DFU_UPLOAD request is less than wLength. (Short frame) the Next State is dfuIDLE In current code, when an UPLOAD is completely performed after the first request (for example with wLength=200 and data read = 9), the DFU state stay at dfuUPLOADIDLE until receiving a DFU_UPLOAD or a DFU_ABORT request even it is unnecessary as the previous DFU_UPLOAD request already reached the EOF. This patch proposes to finish the DFU uploading (don't go to dfuUPLOADIDLE) and completes the control-read operation (go to DFU_STATE_dfuIDLE) when the first UPLOAD response has a short frame as an end of file (EOF) indicator even if it is not explicitly allowed in the DFU specification but this seems logical.
