From: Sean Anderson Date: Fri, 16 Oct 2020 22:57:50 +0000 (-0400) Subject: spi: dw: Add SoC-specific compatible strings X-Git-Tag: v2021.10~398^2~6 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=237e5880f8778ef2d26d029f53b57df56a72db4e;p=platform%2Fkernel%2Fu-boot.git spi: dw: Add SoC-specific compatible strings This adds SoC-specific compatible strings to all users of the designware spi device. This will allow for the correct driver to be selected for each device. Where it is publicly documented, a compatible string for the specific device version has also been added. Devices without publicly-documented device versions include MSCC SoCs, and Arc Socs. All compatible strings except those for SoCFPGAs and some of the versioned strings have been taken from Linux. Since SSI_MAX_XFER_SIZE is determined at runtime, this is not strictly necessary. However, it is a good cleanup and brings things closer to Linux.
