Applied to https://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi.git for-next Thanks! [1/1] spi: lantiq-ssc: Convert to use GPIO descriptors commit: 95f2fd2e52a49b76f896e03802123567b8a89912 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. Thanks, Mark

This switches the Lantiq SSC driver over to use GPIO descriptor handling in the core. The driver was already utilizing the core to look up and request GPIOs from the device tree so this is a pretty small change just switching it over to use descriptors directly instead.
