    pinctrl: replace list_*() with get_*_count() · d1e90e9e
    Viresh Kumar authored
    Most of the SoC drivers implement list_groups() and list_functions()
    routines for pinctrl and pinmux. These routines continue returning
    zero until the selector argument is greater than total count of
    available groups or functions.
    This patch replaces these list_*() routines with get_*_count()
    routines, which returns the number of available selection for SoC
    driver. pinctrl layer will use this value to check the range it can
    This patch fixes all user drivers for this change. There are other
    routines in user drivers, which have checks to check validity of
    selector passed to them. It is also no more required and hence
    Documentation updated as well.
