spi: sc18is602: add support for SC18IS606

2025-07-09T23:47:16Z

Per its datasheet, the SC18IS606 is a functional replacement of the currently supported SC18IS602B, with the only relevant exceptions to this driver being an increased data buffer size (1024 vs 200 bytes) and three (rather than four) chip selects. It also lacks support for quasi-directional GPIO, but the driver does not use this feature anyway, so this is not reflected in the changes. To that end, update the driver to support variable data buffer sizes and add populate the relevant driver private data fields for this new chip. Signed-off-by: Alvin Šipraga

dtoverlays: add overlay for Pi Vision

2025-06-24T08:40:20Z

Add overlay for SECO Pi Vision adapter HAT, with the sn65dsi83 LVDS bridge, a 10.1-inch LVDS panel, and Atmel mxt touch controller For the pi4ioe5v6408 GPIO expander, the equivalent fxl6408 driver is used. Signed-off-by: Alessandro Pecugi

drivers: dwc2: better handle hardware length & alignment issues

2025-06-24T08:11:59Z

The version of the dwc-otg core used in BCM2835 through BCM2712 only does whole-word writes, as well as needing the documented requirement for DMA buffers to start on a word boundary. Also, the alignment method used in the dwc2 driver doesn't handle the case where the URB has the NO_TRANSFER_DMA_MAP flag set, so reject buffers that have unaligned DMA start addresses. At least one whole page should be mapped, so the BCM283x whole-word-write bug should be benign in this case. Signed-off-by: Jonathan Bell

Revert "usb: dwc2: use temporary URB buffer for small control transfers"

2025-06-24T08:11:59Z

This incorrectly matches on urb->setup_packet instead of checking the pipe type, so recycled URBs were incorrectly matched. A more comprehensive fix is forthcoming. This reverts commit 2f2722472e24d7e3360f05e4a8eaa27b6359a206. Signed-off-by: Jonathan Bell

misc: rp1-pio: Don't just reuse the same DMA buf

2025-06-23T13:52:25Z

A missing pointer increment meant that not only was the same buffer being reused again and again, there was also no protection against using it simultaneously for multiple transfers. Fix that basic bug, and also move a similar increment to before the transfer is started, which feels less racy. See: https://github.com/raspberrypi/linux/issues/6919 Signed-off-by: Phil Elwell
