    Subject[RFC PATCH v3 0/5] pinctrl: imx: add pinnmux support
    Date
    The main changes of this new patch series are add dt binding
    support in pinctrl core for pinmux mappings and shows an example
    on using the standard API provided by pinctrl core to register
    pinmux mappings from dts file.
    Then we can remove the old board specifc pinmux mappings from
    generic soc specific code (e.g. mach-imx6q.c).

    Change v2->v3:
    - change the name from of_get_child_number to of_get_child_count
    - pinctrl: add dt binding support for pinmux mappings
    - Add phandle for pinmux mappings for imx6q
    - binding pinmux mappings via pinctrl core API
    - follow the dt convention to use dash '-' for property name

    Changes v1->v2:
    - add a cover letter
    - remove the pin functon and group defines out of driver
    - parsing data from device tree for imx6q support
    - a few minor fixes suggested by Shawn

    Dong Aisheng (5):
    dt: add of_get_child_count helper function
    pinctrl: add dt binding support for pinmux mappings
    pinctrl: imx: add pinctrl imx driver
    ARM: imx6q: using pinmux subsystem
    mmc: sdhci-esdhc-imx: using pinmux subsystem
