The patch

   spi: davinci: Remove chip select GPIO pdata

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: davinci: Remove chip select GPIO pdata

The DaVinci SPI can use either:
- Internal chip selects (inside the SPI host)
- External chip selects (using GPIO)
- External chip selects passed in pdata

The last way of passing external chip selects through
platform data is not used in the kernel. Delete it to make
the code simpler when refactoring GPIO.
