    clk: mux: Add support for specifying parents via DT/pointers · 9611b3aa
    Stephen Boyd authored
    After commit fc0c209c ("clk: Allow parents to be specified without
    string names") we can use DT or direct clk_hw pointers to specify
    parents. Create a generic function that shouldn't be used very often to
    encode the multitude of ways of registering a mux clk with different
    parent information. Then add a bunch of wrapper macros that only pass
    down what needs to be passed down to the generic function to support
    this with less arguments.
    
    Note: the msm drm driver passes an anonymous array through the macro
    which seems to confuse my compiler. Adding a parenthesis around the
    whole thing at the call site seems to fix it but it must be wrong. Maybe
    it's better to split this patch and pick out the array bits there?
