This implements the pinctrl driver for the RZ/N1 family of devices, including the R9A06G032 (RZ/N1D) device. This series was originally written by Michel Pollet whilst at Renesas, and I have taken over this work. Main changes: v7: - Revert changes in v6, and just remove the token pasting v6: - Instead of combining the pin nr and func into a single element, use a pair of 8-bit elements. - Simplified how the MDIO function is calculated v5: - Address Jacopo's further comments - Address Geert's comments v4: - Address Jacopo's comments - Add alternative way to use the pinmux prop. - Remove mention of gpios. - Implement pin_config_group_get() - Fix function to get pin configs, i.e. return -EINVAL when disabled. v3: - Use standard DT props instead of proprietary ones. - Replace virtual pins used for MDIO muxing with extra funcs. - Use pinctrl_utils funcs to handle the maps. - Remove the dbg functions to keep things simple. - Change the way the functions are defined so it is easy to check against the hardware numbering. v2: - Change to generic rzn1 family driver, instead of device specific. - Review comments fixed. - Fix error handling during probe Phil Edworthy (3): dt-bindings: pinctrl: renesas,rzn1-pinctrl: documentation pinctrl: renesas: Renesas RZ/N1 pinctrl driver ARM: dts: r9a06g032: Add pinctrl node .../bindings/pinctrl/renesas,rzn1-pinctrl.txt | 153 +++ arch/arm/boot/dts/r9a06g032.dtsi | 8 + drivers/pinctrl/Kconfig | 10 + drivers/pinctrl/Makefile | 1 + drivers/pinctrl/pinctrl-rzn1.c | 948 ++++++++++++++++++ include/dt-bindings/pinctrl/rzn1-pinctrl.h | 141 +++ 6 files changed, 1261 insertions(+) create mode 100644 Documentation/devicetree/bindings/pinctrl/renesas,rzn1-pinctrl.txt create mode 100644 drivers/pinctrl/pinctrl-rzn1.c create mode 100644 include/dt-bindings/pinctrl/rzn1-pinctrl.h -- 2.17.1
