This patchset contains the initial pinctrl (IOMUX) support for the Broadcom Cygnus SoC. The Cygnus IOMUX controller supports group based mux configuration and allows certain pins to be muxed to GPIO function individually Changes from v3: - Fix the driver to have more proper use of "const" in various places - Other minor improvements Changes from v2: - Consolidate all Broadcom pinctrl drivers into drivers/pinctrl/bcm/* - Change the Cygnus IOMUX driver to use standard Linux pinctrl subnode properties such as "function" and "groups" for pinmux configuration, instead of non-standard properties such as "brcm,function" and "brcm,group" - Use real function names like "spi0", "lcd", "key", and etc. instead of HW specific mux names like "alt1", "alt2", "alt3", and etc. - Add suffix "grp" to all group names - Add support to allow individual pins to be muxed to GPIO function through subsystem callbacks "gpio_request_enable" and "gpio_disable_free", and get rid of all GPIO groups - Other minor improvements in the driver Changes from v1: - Fix a typo in device tree binding document Ray Jui (4): pinctrl: bcm: consolidate Broadcom pinctrl drivers pinctrl: Broadcom Cygnus pinctrl device tree binding pinctrl: cygnus: add initial IOMUX driver support ARM: dts: enable IOMUX for Broadcom Cygnus .../bindings/pinctrl/brcm,cygnus-pinmux.txt | 157 +++ arch/arm/boot/dts/bcm-cygnus.dtsi | 6 + drivers/pinctrl/Kconfig | 19 +- drivers/pinctrl/Makefile | 4 +- drivers/pinctrl/bcm/Kconfig | 34 + drivers/pinctrl/bcm/Makefile | 5 + drivers/pinctrl/bcm/pinctrl-bcm281xx.c | 1455 ++++++++++++++++++++ drivers/pinctrl/bcm/pinctrl-bcm2835.c | 1072 ++++++++++++++ drivers/pinctrl/bcm/pinctrl-cygnus-mux.c | 1088 +++++++++++++++ drivers/pinctrl/pinctrl-bcm281xx.c | 1455 -------------------- drivers/pinctrl/pinctrl-bcm2835.c | 1072 -------------- 11 files changed, 3820 insertions(+), 2547 deletions(-) create mode 100644 Documentation/devicetree/bindings/pinctrl/brcm,cygnus-pinmux.txt create mode 100644 drivers/pinctrl/bcm/Kconfig create mode 100644 drivers/pinctrl/bcm/Makefile create mode 100644 drivers/pinctrl/bcm/pinctrl-bcm281xx.c create mode 100644 drivers/pinctrl/bcm/pinctrl-bcm2835.c create mode 100644 drivers/pinctrl/bcm/pinctrl-cygnus-mux.c delete mode 100644 drivers/pinctrl/pinctrl-bcm281xx.c delete mode 100644 drivers/pinctrl/pinctrl-bcm2835.c -- 1.7.9.5 -- 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
