[PATCH v2] clk: iproc: Do not rely on node name for correct PLL setup

[Stephen Boyd]

Quoting Florian Fainelli (2022-09-05 09:15:03)
> After commit 31fd9b79dc58 ("ARM: dts: BCM5301X: update CRU block
> description") a warning from clk-iproc-pll.c was generated due to a
> duplicate PLL name as well as the console stopped working. Upon closer
> inspection it became clear that iproc_pll_clk_setup() used the Device
> Tree node unit name as an unique identifier as well as a parent name to
> parent all clocks under the PLL.
> 
> BCM5301X was the first platform on which that got noticed because of the
> DT node unit name renaming but the same assumptions hold true for any
> user of the iproc_pll_clk_setup() function.
> 
> The first 'clock-output-names' property is always guaranteed to be
> unique as well as providing the actual desired PLL clock name, so we
> utilize that to register the PLL and as a parent name of all children
> clock.
> 
> Fixes: 5fe225c105fd ("clk: iproc: add initial common clock support")
