Hi, This series adds support for the Apple Mac SMC GPIO driver that was previously posted before the last merge window. I believe all previous review points have been addressed. This series is smaller than the previous posting because I'm splitting this up to allow progress to be made; this driver is dependent on the Apple SMC driver in order to be buildable and usable. It is expected that this Apple SMC driver will be merged via Lee's MFD tree. The Kconfig dependencies this driver from causing build issues until that driver is also merged, so I believe it is appropriate to send this separately. There is no issue if we wish to delay applying this until the core driver has been accepted by Lee. The series is made up of two patches - one patch for the bindings, which now include two compatibles, one specific and one generic. The second patch adds the actual driver itself. v2: updated bindings document .../devicetree/bindings/gpio/gpio-macsmc.yaml | 41 ++++ drivers/gpio/Kconfig | 11 + drivers/gpio/Makefile | 1 + drivers/gpio/gpio-macsmc.c | 245 +++++++++++++++++++++ 4 files changed, 298 insertions(+) create mode 100644 Documentation/devicetree/bindings/gpio/gpio-macsmc.yaml create mode 100644 drivers/gpio/gpio-macsmc.c -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 40Mbps down 10Mbps up.
