This series adds the AIU audio controller for Meson8 and Meson8b. The AIU audio controller has been found to work fine with out-of-tree patches for HDMI audio (over I2S). SPDIF output also works (tested with a scope). Endless Mini (EC-100) has an RT5640 audio codec. The driver for this codec can be selected since commit 08c56cab302a05 ("ASoC: rt5640: Make codec selectable"), which is part of Linux 5.14-rc1. While support is not perfect (due to us lacking proper support for configuring GPIO_BSD_EN) audio output still works fine.
This series is based on my bugfix patch "ARM: dts: meson8: Use a higher default GPU clock frequency" from [0]
Changes since v1 at [1]: - added sound-name-prefix = "AIU"; to the first patch to make it identical to what we have in meson-gx.dtsi - drop audio-routing property from the sound card in the second patch as it doesn't appear to be needed
