spi: spi-fsl-dspi: Add specific compatibles for all Layerscape SoCs (50b62071) · Commits · 戴 / test

Make the second compatible string optional for LS1012A, LS1088A and LS2080A. Old versions of the spi-fsl-dspi.c driver still need to probe on the old, generic compatible string for these controllers (such as "fsl,ls1021a-v1.0-dspi") which provides less functionality. Document the device tree bindings for LS1043A and LS1046A, whose bindings are already in use in fsl-ls1043a.dtsi and fsl-ls1046a.dtsi. Introduce new compatible strings for LS1028A and LX2160A. There will be no second compatible string for these. Signed-off-by:
