This patchset adds audio related devices to g12a SoC family.
It adds the clock controller as well as the memory, tdm, spdif
and pdm interfaces.
At this stage, the HDMI and internal audio DAC are still missing.
Notice the use of the pinconf DT property 'drive-strength-microamp'.
Support for this property is not yet merged in meson pinctrl driver but
the DT part as been acked by the DT maintainer [0] so it should be safe
to use.
Changes since v1: [1]
* Had missing axg compatibles for the fifos (one last harmless change ...)
* Fix a few underscores in node names

Oops, I replied to v1, but I actually queued this v2 series.
Thanks,
