* usb: xhci-dwc3: Add support for USB 3.1 controllersMark Kettenis2021-09-221-1/+2
| | | | | | | | This adds support for the DWC_sub31 controllers such as those found on Apple's M1 SoC. This version of the controller seems to work fine with the existing driver. Signed-off-by: Mark Kettenis <kettenis@openbsd.org>
* usb: ehci-mx6: use phy_type from device treeMatthias Schiffer2021-09-221-2/+23
| | | | | | | | | | | Allow using different PHY interfaces for multiple USB controllers. When no value is set in DT, we fall back to CONFIG_MXC_USB_PORTSC for now to stay compatible with current board configurations. This also adds support for the HSIC mode of the i.MX7.

* usb: xhci-dwc3: Add support for clocks/resetsSamuel Holland2021-09-221-0/+56
| | | | | | | | | | Some platforms, like the Allwinner H6, do not have a separate glue layer around the dwc3. Instead, they rely on the clocks/resets/phys referenced from the dwc3 DT node itself. Add support for enabling the clocks/resets referenced from the dwc3 DT node. Signed-off-by: Samuel Holland <samuel@sholland.org> Signed-off-by: Andre Przywara <andre.przywara@arm.com>
* usb: xhci-pci: Move reset logic out of XHCI coreSamuel Holland2021-09-223-41/+48
| | | | | | | | | | | | | | | | | | | | | | Resetting an XHCI controller inside xhci_register undoes any register setup performed by the platform driver. And at least on the Allwinner H6, resetting the XHCI controller also resets the PHY, which prevents the controller from working. That means the controller must be taken out of reset before initializing the PHY, which must be done before calling xhci_register. The logic in the XHCI core was added to support the Raspberry Pi 4 (although this was not mentioned in the commit log!), which uses the xhci-pci platform driver. Move the reset logic to the platform driver, where it belongs, and where it cannot interfere with other platform drivers. This also fixes a failure to call reset_free if xhci_register failed.

* usb: Enforce DM_USB migration for USB_HOST devices.Tom Rini2021-07-188-24/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | As the deadline for migration to DM_USB, when using a USB host controller has now gone two years past the deadline, enforce migration. This is done by: - Ensuring that all host controller options (other than the very legacy old MUSB ones) now select USB_HOST. USB_HOST now enforces DM_USB and OF_CONTROL. - Remove other parts of Kconfig logic that had platforms pick DM_USB. - To keep Kconfig happy, have some select statements test for USB_HOST as well. - Re-order some Kconfig entries and menus so that we can cleanly pick host or gadget roles. For the various HCD options that have platform glue options, group them together and update dependencies in some cases. - As SPL_DM_USB is not required, on platforms that had not yet enabled it, disable it.

* usb: musb-new: Add glue driver for ST-Ericsson Ux500Stephan Gerhold2021-07-144-2/+191
| | | | | | | | | | | | | | | The ST-Ericsson DB8500 SoC contains a MUSB OTG controller which supports both host and gadget mode. For some reason there is nothing special about it - add a simple glue driver for Ux500 that literally just sets up MUSB together with a generic PHY. There are no SoC-specific registers etc needed to make USB work. The new Ux500 glue driver is only tested to work with DM_USB and DM_USB_GADGET. Both host and gadget mode work fine on the u8500 "stemmy" board that is already present in U-Boot.

* | usb: dwc2: Avoid delay when initializing USB peripheral by dwc2João Loureiro2021-06-091-1/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | When `usb start` is called on the terminal, the dwc2 driver will try to start every USB device as host first, even if it is explicitly configured as peripheral in the device tree (dr_mode = "peripheral"). So to avoid an unwanted 15 seconds delay when initializing the usb (one second per channel = 1s x 15), this patch adds a check to the initialization, and will skip host initialization of the device is explicitly set as peripheral. The checking is already done similarly in the `drivers/usb/gadget/dwc2_udc_otg.c` driver. Signed-off-by: João Loureiro <joaofl@gmail.com>

* usb: musb-new: Extend and move Allwinner quirk into KconfigAndre Przywara2021-05-162-2/+11
| | | | | | | | | | | | | | | | | | | | All newer Allwinner SoCs (since about 2013) miss the CONFIGDATA register in their MUSB implementation, so they need a quirk to hardcode this. Currently this quirk depends on listing the SoCs affected in musb_reg.h, which means that this list needs to grow with every new chip. Move the quirk feature into Kconfig, next to PIO_ONLY, and change the default to y (for Allwinner builds), while listing the early implementations as exceptions. This fixes USB peripheral operation on some newer SoCs, which were not explicitly listed before. Tested on H6, H616, R40 (which were broken before), and also on the H5 and A20, for regressions.

* usb: ehci-hcd: Add IAA handshake for removing async QHYe Li2021-04-222-0/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | According to EHCI spec, software needs to do handshake with HC for safely removing QH from async list. This handshake is implemented by setting IAAD (Interrupt on Async Advance Doorbell) bit in USB_USBCMD register and poll the IAA (Interrupt on Async Advance bit) in the USB_USBSTS to ensure the HC has released all on-chip state that may potentially reference one of the data structures just removed. Current codes only check active status of the last QTD, but this can't ensure the QH is released from HC. We can meet unrecoverable "EHCI timed out on TD" errors when running UEFI SCT tests on USB disk. The USB_ASYNCLISTADDR register is changed to a invalid address when the issue happens. It is fixed after adding the IAA handshake. Steps to reproduce the issue: 1. Build the UEFI SCT from https://github.com/tianocore/edk2-test 2. Build the EDK2 UEFI Shell from https://github.com/tianocore/edk2 3. Copy SCT files and Shell.efi to USB disk FAT partition 4. Load the Shell.efi from USB FAT, and run bootefi to execute it 5. After booting into Shell, enter the SCT directory and run "sct -a" to execute all tests. 6. Tests run about 1 hour and stop with many EHCI timeout errors like EHCI timed out on TD - token=0x801f8c80 Signed-off-by: Ye Li <ye.li@nxp.com>

Moreover address of FIFO buffer for endpoint 0 cannot be programmed, it is fixed to 0x0. Sharing address space between more endpoints cause data loss and unexpected errors. This patch is fixing transmission of characters over usbtty serial console and allows using of usbtty for debugging purposes on Nokia N900.

* usb: musb: Fix handling interrupts for EP0 and SET ADDRESS commmandPali Rohár2021-03-031-8/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Interrupt for EP0 is indicated in intrtx register via first bit. This bit is set for both RX and TX despite register has only TX in its name. First bit in intrrx register is reserved, not used and never set. So remove calling musb_peri_ep0() function at every iteration of udc_irq() and musb_peri_rx() and call it only from musb_peri_tx() when correct interrupt bit in initrtx it set. Address from SET ADDRESS command must be set to faddr register only after acknowledging SERV_RXPKTRDY followed by received EP0 interrupt. So prior calling musb_peri_ep0_set_address() check for EP0 interrupt instead of (incorrect) MUSB_INTR_SOF interrupt. This patch fixes issue that host (computer) cannot register U-Boot USB device and is failing with errors: usb 1-1: new full-speed USB device number 86 using xhci_hcd usb 1-1: Device not responding to setup address. usb 1-1: Device not responding to setup address. usb 1-1: device not accepting address 86, error -71 U-Boot was writing address to faddr register too early and did not wait for correct interrupt after which should update address.

* usb: musb: Fix receiving of bigger buffersPali Rohár2021-03-031-1/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If musb_peri_rx_ep() was called to process received HW buffer but U-Boot cannot read it yet (e.g. because U-Boot SW buffer is full) then interrupt was marked as processed also when HW buffer stayed unprocessed. U-Boot tried to process this buffer again when it received interrupt again, but it can receive it only when sender (host) sends a new data. As sender (host) is not going to send a new data until U-Boot process current data this issue caused a deadlock in case sender (host) is emitting data faster than U-Boot can process it. Reading musb intrrx register automatically clears this register and marks interrupt as processed. So to prevent marking interrupt in U-Boot as processed, adds a new variable pending_intrrx which would contain unprocessed bits of intrrx register. For a second step, every time when musb_peri_rx_ep() is called and there are waiting data to be processed (signaled by MUSB_RXCSR_RXPKTRDY) either acknowledge sender (via musb_peri_rx_ack()) that whole HW buffer was processed or set corresponding bit in pending_intrrx that HW buffer was not fully processed yet and next iteration is required after U-Boot allocates space for reading HW buffer. This patch fixes receiving large usb buffers, e.g. file transfer via Kermit protocol implemented by 'loadb' U-Boot command over usbtty serial console.

| | | | | | | | | | | | | | | | | If udc_endpoint_write() was called with bigger payload which does not fit into one USB packet it is needed to transmit payload in more USB packets. First packet is transmitted by udc_endpoint_write() call itself and other packets are put into waiting queue. Implement function musb_peri_tx() which checks if endpoints are ready for transmit and continue transmission of waiting queue. This patch fixes sending big output from printenv command over usbtty serial console.
