2024-05-19Revert "Merge patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet""Tom Rini
When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay Ethernet"' I failed to notice that b4 noticed it was based on next and so took that as the base commit and merged that part of next to master. This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

2021-03-03usb: musb: Ensure that we set musb dynamic FIFO buffer for every endpointPali Rohár
If we do not set FIFO buffer address and size for some endpoint which is in use then default programmed address 0x0 would be used which is in conflict with address of FIFO buffer for endpoint 0. 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.

2021-03-03usb: musb: Fix handling interrupts for EP0 and SET ADDRESS commmandPali Rohár
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.

2021-03-03usb: musb: Fix receiving of bigger buffersPali Rohár
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.

2021-03-03usb: musb: Fix transmission of bigger buffersPali Rohár
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.

2019-12-02common: Move serial_printf() to the serial headerSimon Glass
Move this function header to serial.h since this function is clearly related to serial. The function itself stays in console.c since we don't have a single serial file. DM and non-DM each has a separate file so we would have to either create a new common serial file, or repeat the function in both serial.c and serial-uclass.c, neither of which seem worthwhile.

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>
