Document the "axiado,ax3005-spi" SoC-specific compatible with "snps,dwc-ssi-1.01a" as its fallback. This preserves identification of the AX3005 integration while allowing the controller to use the existing DesignWare APB SSI support. Signed-off-by: Swark Yang Reviewed-by: Krzysztof Kozlowski --- This SPI binding was previously submitted as patch 6/8 of the AX3005 v3 multi-subsystem series. Following maintainer feedback, the binding updates are now submitted separately to their respective subsystem maintainers, as there are no cross-subsystem dependencies requiring them to be submitted together. This submission contains only the AX3005 SPI binding. The corresponding SPI controller nodes remain in the separate AX3005 arm64 Devicetree series. Changes in v4: - Submit the SPI binding separately from the previous multi-subsystem AX3005 series. - Expand the commit message to explain compatibility with the Synopsys DesignWare APB SSI 1.01a programming interface. - Replace the AX3005-specific schema entry with a generic group for vendor controllers compatible with v1.01a. - Place the new group after the vendor-controller group using "snps,dw-apb-ssi" as its fallback. - Use an enum for the vendor-specific compatible so that the group can be extended with additional controllers.
