Subject: [PATCH] clk: meson: meson8b: set audio output clock hierarchy
Date:   Thu, 20 Feb 2020 21:44:33 +0100

The aiu devices peripheral clocks needs the aiu and aiu_glue clocks to
operate. Reflect this hierarchy in the clock tree.

Fixes: e31a1900c1ff73 ("meson: clk: Add support for clock gates")

This takes Jerome's patch for GXBB and ports it to the Meson8* SoCs.
Hence the Suggested-by.
