Hi Geert, this is 5th round of gpio/pincontroller for RZ/A1 devices. I have updated the pin controller driver to use the newly introduced "pinctrl_enable()" function. This is required since v4.11-rc7 as otherwise, as reported by Chris Brandt, the pin controller does not start. I have incorporated your comments on the device tree bindings documentation, and added to pinctrl-generic.h header file two macros to unpack generic properties and their arguments. Tested with SCIF, RIIC, ETHER and gpio-leds on Genmai board. Thanks j v1 -> v2: - change pin configuration flags as suggested by Chris - gpio set direction function fixed as suggested by Chris - add some more example on pin configuration flag usage to dt-binding doc - fix gpio-controller names to remove unit address as suggested by Geert - some comments chopped here and there to make the driver less verbose v2 -> v3: - fix grammar and syntax in comment and documentation - fix code style (reverse xmas tree ordering in variable declaration) - use irqsave/irqrestore in spinlock lock/unlock - use devm_ version of kasprintf (memory returned was not properly free) - use bitops.h operation ffs and fls to make sure a single bit is set in pmx mask - Add Geert's reviewed-by to DTS patches v3 -> v4: - use "pinmux" property in pmx sub-nodes in place of "renesas,pins" - use pinconf standard properties to set pin mux additional flags - add "bi-directional" and "output-enable" to pinconf generic properties - perform pmx function parsing at dt_node_to_map() time - change DT bindings to use GENERIC_PINCONF - change DT bindings to allow sub-nodes to have "pinmux" property specified - several renames (register names, DT parse functions, set_mux() function) v4 -> v5: - use pinctrl_enable() function in pin controller registration function - update bindings documentation to incorporate Geert's comments - add generic properties unpack macros Jacopo Mondi (10): pinctrl: generic: Add bi-directional and output-enable pinctrl: generic: Add macros to unpack properties pinctrl: Renesas RZ/A1 pin and gpio controller dt-bindings: pinctrl: Add RZ/A1 bindings doc arm: dts: dt-bindings: Add Renesas RZ/A1 pinctrl header arm: dts: r7s72100: Add pin controller node arm: dts: genmai: Add SCIF2 pin group arm: dts: genmai: Add RIIC2 pin group arm: dts: genmai: Add user led device nodes arm: dts: genmai: Add ethernet pin group .../bindings/pinctrl/pinctrl-bindings.txt | 2 + .../bindings/pinctrl/renesas,rza1-pinctrl.txt | 219 +++++ arch/arm/boot/dts/r7s72100-genmai.dts | 76 ++ arch/arm/boot/dts/r7s72100.dtsi | 78 ++ drivers/pinctrl/Kconfig | 11 + drivers/pinctrl/Makefile | 1 + drivers/pinctrl/pinconf-generic.c | 3 + drivers/pinctrl/pinctrl-rza1.c | 995 +++++++++++++++++++++ include/dt-bindings/pinctrl/r7s72100-pinctrl.h | 16 + include/linux/pinctrl/pinconf-generic.h | 7 +- 10 files changed, 1407 insertions(+), 1 deletion(-) create mode 100644 Documentation/devicetree/bindings/pinctrl/renesas,rza1-pinctrl.txt create mode 100644 drivers/pinctrl/pinctrl-rza1.c create mode 100644 include/dt-bindings/pinctrl/r7s72100-pinctrl.h -- 2.7.4 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
