power: regulator: add AXP318W support

2026-01-25T23:29:32Z

The PMIC is also known as AXP819 in vendor pmu code For DCDC6, 8, 9, the underlying hardware support more than two levels voltage step tuning, but for now only first two levels are implemented in this driver, hence highest voltage will be limited at seccond level. It actual meets board requirement in current design, and we've verified it in Radxa Cubie A7A board. Following are detail explanation of voltage tuning stpes for those DCDCs: DCDC | voltage range | units | steps | implemented 6 | 0.5 - 1.2 | 10 mV | 71 | Y . | 1.22 - 1.54 | 20 mV | 17 | Y . | 1.8 - 2.4 | 20 mV | 31 | N . | 2.44 - 2.76 | 40 mV | 9 | N -------------------------------------------------- 8/9 | 0.5 - 1.2 | 10 mV | 71 | Y . | 1.22 - 1.84 | 20 mV | 32 | Y . | 1.9 - 3.4 | 100mV | 16 | N Signed-off-by: Yixun Lan Reviewed-by: Andre Przywara

sunxi: extend R528/T113-s3/D1(s) DRAM initialisation

2026-01-25T23:29:32Z

The T113-s4 SoC is using the same die as the T113-s3, but comes with 256MiB of co-packaged DRAM. Besides the doubled size, the DRAM chip seems to be connected slightly differently, which requires to use a different pin remapping. Extend the DRAM initialisation code to add support for the T113-S4 aka T113M4020DC0 by checking the SoC's CHIPID, which is stored in the first word of the SID efuses.

usb: xhci: fix DMA address corruption in abort_td

2026-01-25T09:40:42Z

When aborting a Transfer Descriptor (TD), the xHCI driver updates the device dequeue pointer by converting the virtual enqueue TRB pointer into a DMA address. Previously, the code OR-ed the ring's Dequeue Cycle State (DCS) bit into the virtual TRB pointer before passing it to xhci_trb_virt_to_dma(). This produced an unaligned virtual address (e.g. ending in 0x...1). Inside xhci_trb_virt_to_dma(), the offset calculation: segment_offset = trb - seg->trbs; operated on this unaligned pointer, resulting in an incorrect TRB index. In wraparound cases, this caused the bounds check to fail and the function to return 0. As a result, a SET_DEQ_PTR command was issued with a DMA address of 0x0, leading to controller hangs and transfer timeouts, most commonly when aborting TDs near the end of a ring segment (e.g. index 63). Fix this by translating the aligned virtual TRB pointer to a DMA address first, and only then applying the DCS bit to the resulting physical address.

video: add DejaVu Mono font

2026-01-24T16:01:22Z

A TrueType font for U-Boot should fulfill the following requirements: * mono spaced * support full code page 437 * easily readable Unfortunately none of the fonts provided with U-Boot fulfills all of these requirements. Let's add the DejaVu Mono font. To reduce the code size the characters are limited to code page 437. Signed-off-by: Heinrich Schuchardt Reviewed-by: Simon Glass

mmc: Fix retry logic in sd_get_capabilities

2026-01-22T02:38:50Z

In sd_get_capabilities an ACMD is sent (SD_CMD_APP_SEND_SCR), which requires sending APP_CMD (MMC_CMD_APP_CMD) before. Currently, the ACMD is retried on error, however APP_CMD isn't. In this case, when the ACMD fails and it is tried again, the retry attempts will not be handled as ACMD, which is wrong. The fix performs the retry attempts on the sequence of APP_CMD and the ACMD together. Signed-off-by: Yanir Levin Reviewed-by: Eran Moshe Signed-off-by: Peng Fan

mmc: mmc-uclass: Use max-frequency from device tree with driver default fallback

2026-01-22T02:38:48Z

Use dev_read_u32_default() instead of dev_read_u32() to read the "max-frequency" property from device tree. This preserves the driver-set cfg->f_max value when the optional "max-frequency" property is not present, ensuring the controller's default frequency is used as fallback rather than being overwritten.
