I followed your instructions but you see the results are mixed, which is why I asked for clarification, wondering if you meant something else, since I already used one of the two apparently correct options. 53df0409b59b Merge branch 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi.git f63175733f91 spi: dt-bindings: armada-3700: convert to dtschema 1f48cbd6f00f spi: renesas,sh-msiof: Add r8a779h0 support eb4fdb4bf46f spi: dt-bindings: cdns,qspi-nor: make cdns,fifo-depth optional 52826aee484b spi: dt-bindings: cdns,qspi-nor: add mobileye,eyeq5-ospi compatible 002514d91fcc spi: dt-bindings: cdns,qspi-nor: sort compatibles alphabetically 02ec75edaa94 dt-bindings: treewide: add access-controllers description 80a38bfbbd59 spi: dt-bindings: introduce FIFO depth properties ee09bb727bff spi: dt-bindings: samsung: make dma properties not required 666db8fd4265 spi: dt-bindings: atmel,at91rm9200-spi: remove 9x60 compatible from list ff690e75d64b spi: dt-bindings: samsung: add google,gs101-spi compatible 737cf74b3800 spi: dt-bindings: samsung: Add Exynos850 SPI 18ab9e9e8889 dt-bindings: spi: nxp-fspi: support i.MX93 and i.MX95 6685d552a0cc dt-bindings: spi: fsl-lpspi: support i.MX95 LPSPI f034a151059a dt-bindings: spi: stm32: add st,stm32mp25-spi compatible e1fca6957f19 spi: dw: Remove Intel Thunder Bay SOC support 4c3ff31a85e3 spi: axi-spi-engine improvements 252eafe11ffc dt-bindings: spi: axi-spi-engine: convert to yaml 54a1dc08e173 spi: dt-bindings: renesas,rspi: Document RZ/Five SoC 09388379b6d7 spi: add stm32f7-spi compatible 1b2e883e1af8 spi: Merge up fix 4056d88866e5 spi: renesas,rzv2m-csi: Add CSI (SPI) target related property 9f778f377cd3 spi: dt-bindings: Make "additionalProperties: true" explicit da6de6d3ecc1 spi: qup: Allow scaling power domains and 0fc57bf1b2ff spi: dt-bindings: st,stm32-spi: Move "st,spi-midi-ns" to spi-peripheral-props.yaml d15befc0cef4 spi: dt-bindings: qup: Document interconnects e6419c35f0d9 spi: dt-bindings: qup: Document power-domains and OPP 3b4e5194138b dt-bindings: spi: fsl-imx-cspi: Document missing entries b0ef97ac89a7 spi: dt-bindings: arm,pl022: Move child node properties to separate schema 8f447694c23a Merge tag 'devicetree-for-6.6' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux 47aab53331ef dt-bindings: Fix typos 0e19118ab24b dt-bindings: spi: convert spi-brcm63xx.txt to YAML 0d2b6a1b8515 dt-bindings: qspi: cdns,qspi-nor: Add clocks for StarFive JH7110 SoC ffae65fb1ae4 dt-bindings: spi: spi-cadence: Add label property 883622752403 dt-bindings: spi: spi-cadence: Describe power-domains property b350e6c6297a spi: dt-bindings: add loongson spi 026badeb7055 spi: fspi: Add power-domains to the DT bindings 49aa77165c00 spi: lpspi: Add power-domains to the DT bindings 8858babff615 dt-bindings: spi: add reference file to YAML b8968c388b69 dt-bindings: spi: Convert Tegra114 SPI to json-schema 17a9ab02f72c dt-bindings: spi: tegra-sflash: Convert to json-schema 8c87a46e2ce3 dt-bindings: spi: tegra-slink: Convert to json-schema 6c1561fb9005 Merge tag 'soc-dt-6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc e884a133340a spi: dt-bindings: atmel,at91rm9200-spi: fix broken sam9x7 compatible a3eb95484f27 spi: dt-bindings: atmel,at91rm9200-spi: add sam9x7 compatible 14dde0746e67 spi: dt-bindings: Add bindings for RZ/V2M CSI 01fa9edd8bcf spi: dt-bindings: stm32: do not disable spi-slave property for stm32f4-f7 e6afe03351ac spi: stm32: disable spi-slave property for stm32f4-f7 7bac98a338d6 spi: dt-bindings: snps,dw-apb-ssi: Add compatible for Intel Mount Evans SoC d5c421d24d7e dt-bindings: xilinx: Switch xilinx.com emails to amd.com 34fcc0f0a410 spi: dt-bindings: socionext,uniphier: drop address/size-cells bbd25f1ae8bf spi: dt-bindings: samsung: drop cs-gpios > > > Best regards, > Krzysztof >

I followed your The correct is the latter, although I see now Mark stopped stripping dt-bindings in such case. Log is still suggesting that (git log --oneline -- Documentation/devicetree/bindings/spi/ | grep "^[0-9a-f]\+ spi:" | wc -l gives 370 vs 130), although I understand now different approach. It's also mentioned here: https://www.kernel.org/doc/html/latest/devicetree/bindings/submitting-patches.html Best regards, Krzysztof
