Subject: spi: spi-fsl-dspi: Add specific compatibles for all Layerscape SoCs
Git-commit: 50b62071deab48c1a69c471f9a7d0c8ff9ef23eb
Patch-mainline: v5.7-rc1
References: jsc#SLE-12251
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.
