The SPI controller found in the RK3506 SoC is still compatible to the original one introduced with the RK3066, so add the RK3506 compatible to the list of its variants.

2025-10-02spi: dt-bindings: cadence: add soc-specific compatible strings for zynqmp ↵Conor Dooley1-3/+8
and versal-net When the binding for the Cadence spi controller was written, a dedicated compatible was added for the zynq device. Later when zynqmp and versal-net, which also use this spi controller IP, were added they did not receive soc-specific compatibles. Add them now, with a fallback to the existing compatible for the r1p6 version of the IP so that there will be no functional change. Retain the r1p6 in the string, to match what was done for zynq. Disallow the cdns,spi-r1p6 compatible in isolation to "encourage" people to actually add soc-specific compatible strings in the future.

https://git.kernel.org/pub/scm/linux/kernel/git/sven/linux into soc/drivers Apple SoC driver updates for 6.18 Krzysztof Kozlowski asked us to move away from generic compatibles: - Adjust all dt-bindings to use apple,t8103-XXXX instead of apple,XXXX as fallback and add a comment that the old generic list should no longer be extended. - Add new fallback compatibles to pinctrl, pmdomain, spi, and mca drivers. These changes have been Acked by their subsystem maintainers to be merged through our tree together with the dt-bindings. Support for pre-M1 Apple Silicon: - SART and mailbox gain support for Apple's A11, which are both required for NVMe. - NVMe also gains support for Apple's A11 and the nvme maintainers prefer that we merge this through the soc tree together with the mailbox and SART changes. - SPMI compatibles for A11 and T2 have been added, also going through the soc tree due to conflicts with the generic compatible removal and because no driver change is required.

2025-09-03spi: spi-fsl-dspi: Target mode improvementsMark Brown1-0/+5
Merge series from James Clark <james.clark@linaro.org>: Improve usability of target mode by reporting FIFO errors and increasing the buffer size when DMA is used. While we're touching DMA stuff also switch to non-coherent memory, although this is unrelated to target mode. With the combination of the commit to increase the DMA buffer size and the commit to use non-coherent memory, the host mode performance figures are as follows on S32G3: # spidev_test --device /dev/spidev1.0 --bpw 8 --size <test_size> --cpha --iter 10000000 --speed 10000000 Coherent (4096 byte transfers): 6534 kbps Non-coherent: 7347 kbps Coherent (16 byte transfers): 447 kbps Non-coherent: 448 kbps Just for comparison running the same test in XSPI mode: 4096 byte transfers: 2143 kbps 16 byte transfers: 637 kbps These tests required hacking S32G3 to use DMA in host mode, although the figures should be representative of target mode too where DMA is used. And the other devices that use DMA in host mode should see similar improvements.

2025-05-06AsoC: Phase out hybrid PCI devresMark Brown1-12/+7
Merge series from Philipp Stanner <phasta@kernel.org>: A year ago we spent quite some work trying to get PCI into better shape. Some pci_ functions can be sometimes managed with devres, which is obviously bad. We want to provide an obvious API, where pci_ functions are never, and pcim_ functions are always managed. Thus, everyone enabling his device with pcim_enable_device() must be ported to pcim_ functions. Porting all users will later enable us to significantly simplify parts of the PCI subsystem. See here [1] for details. This patch series does that for sound. Feel free to squash the commits as you see fit. P. [1] https://elixir.bootlin.com/linux/v6.14-rc4/source/drivers/pci/devres.c#L18

MSIOF-SPI/I2S are using same DT compatible properties. MSIOF-I2S uses Of-Graph for Audio-Graph-Card/Card2, MSIOF-SPI doesn't use Of-Graph. Adds schema for MSIOF-I2S (= Sound).
