SubjectApplied "spi: spi-fsl-dspi: Add specific compatibles for all Layerscape SoCs" to the spi tree
The patch

spi: spi-fsl-dspi: Add specific compatibles for all Layerscape SoCs

has been applied to the spi tree at

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Subject: [PATCH] spi: spi-fsl-dspi: Add specific compatibles for all
Layerscape SoCs

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.
