2024-04-15mmc: dw_mmc: Don't return error if data busy timeoutYang Xiwen
As described in [1], some poor hardware or cards would fail to release the bus and keep driving data lines low. Ignore it and send the next cmd directly seems okay for most cases.

2024-04-15mmc: renesas-sdhi: Do not access SCC during tuning in send_cmd callbackMarek Vasut
Do not access SCC when sending commands during tuning operation as that will disrupt the tuning operation. The tuning operation is adjusting the SCC settings itself in execute_tuning callback. When renesas_sdhi_execute_tuning() is called by the MMC core code, a loop which consists of renesas_sdhi_prepare_tuning(), mmc_send_tuning() and renesas_sdhi_compare_scc_data() iterates over each SCC tuning tap. The renesas_sdhi_prepare_tuning() configures the SCC tuning tap number into hardware, mmc_send_tuning() triggers transfer of tuning block which depends on the bus mode for which the bus is currently being tuned, this information is supplied by the MMC core code, and finally renesas_sdhi_compare_scc_data() tests the received tuning block for validity. Because renesas_sdhi_prepare_tuning() configures the SCC tuning tap into the hardware to fit the tuning operation, mmc_send_tuning() which triggers command transfer using renesas_sdhi_send_cmd() must not manipulate with the SCC in any way. Currently renesas_sdhi_send_cmd() does unconditionally call renesas_sdhi_check_scc_error(), which may adjust the SCC tuning tap position by writing RENESAS_SDHI_SCC_TAPSET, which would overwrite the required tuning configuration set by renesas_sdhi_prepare_tuning() and disrupt the tuning operation. Fix this by skipping the renesas_sdhi_check_scc_error() call in case the MMC subsystem is in tuning state. This way, the SCC settings are left unmodified by command transfer during tuning operation.

2024-04-15mmc: renesas-sdhi: Stop transmission in case tuning block transfer failsMarek Vasut
The current code uses the state of tuning block received by SCC to determine whether or not to send transmission stop command. This is not correct. Use the state of tuning block transfer to determine whether or not to send transmission stop command instead, because the transmission stop command has to be sent in case the tuning block transfer failed. This requires two changes, separate variable to store and check the state of tuning block received by SCC, and another separate variable to store and check return value from transmission stop command.

2024-04-15mmc: tmio: Check INFO1 for completion during DMA transferMarek Vasut
In case a CRC error occurs during DMA transfer, the transfer completion flag is not set in TMIO_SD_DMA_INFO1 and the transfer would eventually time out. The timeout could be very long in case the transfer consists of a large amount of blocks, the base timeout is 10 seconds and every block adds 100 us more. In case a CRC error does occur, a completion flag is set in a different register, TMIO_SD_INFO1. Use this other completion flag to detect DMA transfer ended and stop waiting for TMIO_SD_DMA_INFO1 completion flag. This reduces the lengthy timeout in case of an error. The unconditional check of TMIO_SD_DMA_INFO2 register for DMA related errors must not be skipped in any case to actually recognize the DMA error and report it.

2024-04-12Merge patch series "Introduce ICSSG Ethernet driver"Tom Rini
MD Danish Anwar <danishanwar@ti.com> says: Introduce ICSSG PRUETH support in uboot. The ICSSG driver is used in TI AM654 SR2.0. The ICSSG PRU Sub-system runs on EMAC firmware. This series Introduces support for ICSSG driver in uboot. This series has been tested on AM65x SR2.0, and the ICSSG interface is able to ping / dhcp and boot kernel using tftp in uboot. To use ICSSG2 ethernet, the ICSSG firmware needs to be loaded to PRU RPROC cores and RPROC cores need to be booted with the firmware. This step is done inside driver similar to kernel. The remoteproc driver uses request_fw_into_buf() API from fs-loader driver to load and start rproc with the required firmwares. This series only introduces driver files. The device tree and config changes to enable ICSSG driver will be introduced later.

This driver caters to both slices / ports of the icssg subsystem. Since it is not possible for Ethernet driver to register more than one port for a given instance, this patch introduces top level PRUETH as UCLASS_MISC and binds UCLASS_ETH to individual ports in order to support bringing up more than one Ethernet interface in U-Boot.

2024-04-09riscv: don't read riscv, isa in the riscv cpu's get_desc()Conor Dooley
cpu_get_desc() for the RISC-V CPU currently reads "riscv,isa" to get the description, but it is no longer a required property and cannot be assummed to always be present, as the new "riscv,isa-extensions" and "riscv,isa-base" properties may be present instead. On RISC-V, cpu_get_desc() has two main uses - firstly providing an informational name for the CPU for smbios or at boot with DISPLAY_CPUINFO etc and secondly it forms the basis of ISA extension detection in supports_extension() as it returns (a portion of) an ISA string. cpu_get_desc() returns a string, which aligned with "riscv,isa" but the new property is a list of strings. Rather than add support for the list of strings property, which would require creating an isa string from "riscv,isa-extensions", modify the RISC-V CPU's implementaion of cpu_get_desc() return the first compatible as the cpu description instead. This may be fine for the informational cases, but it would break extension dtection, given supports_extension() expects cpu_get_desc() to return an ISA string. Call dev_read_string() directly in supports_extension() to get the contents of "riscv,isa" so that extension detection remains functional. As a knock-on affect of this change, extension detection is no longer broken for long ISA strings. Previously if the ISA string exceeded the 32 element array that supports_extension() passed to cpu_get_desc(), it would return ENOSPC and no extensions would be detected. This bug probably had no impact as U-Boot does not currently do anything meaningful with the results of supports_extension() and most SoCs supported by U-Boot don't have anywhere near that complex of an ISA string. The QEMU virt machine's CPUs do however, so extension detection doesn't work there. Signed-off-by: Conor Dooley <conor.dooley@microchip.com> reviewed-by: Leo Yu-Chi Liang <ycliang@andestech.com>

2024-04-05usb: xhci: Set up endpoints for the first 2 interfacesJanne Grunau
The xhci driver currently only does the necessary initialization for endpoints found in the first interface descriptor. Apple USB keyboards (released 2021) use the second interface descriptor for the HID keyboard boot protocol. To allow USB drivers to use endpoints from other interface descriptors the xhci driver needs to ensure these endpoints are initialized as well. Use USB_MAX_ACTIVE_INTERFACES to control how many interface descriptors are considered during endpoint initialisation. For now define it to 2 as that is sufficient for supporting the Apple keyboards.
