Subject: [PATCH 0/2] Meson8/Meson8b: sound card support

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]
