Quoting Stephen Boyd (2019-08-26 14:20:42)
> The return value of of_parse_clkspec() is peculiar. If the function is
> called with a NULL argument for 'name' it will return -ENOENT, but if
> it's called with a non-NULL argument for 'name' it will return -EINVAL.
> This peculiarity is documented by commit 5c56dfe63b6e ("clk: Add comment
> about __of_clk_get_by_name() error values").
> 
> Let's further document this function so that it's clear what the return
> value is and how to use the arguments to parse clk specifiers.
