Subject: [PATCH v2 13/32] clk: at91: clk-audio-pll: add support for parent_hw
From: Claudiu Beznea <claudiu.beznea@...on.dev>
Add support for parent_hw in audio pll clock drivers.
With this parent-child relation is described with pointers rather
than strings making registration a bit faster.
All the SoC based drivers that rely on clk-audio-pll were adapted
to the new API change. The switch itself for SoCs will be done
in subsequent patches.
Signed-off-by: Claudiu Beznea <claudiu.beznea@...on.dev>
[ryan.wanner@...rochip.com: Remove SoC specific changes as they are
going to be coalesced into one SoC specific commit.]
