[PATCH v2 0/5] arm64: dts: freescale: Share the Toradex NAU8822 BTL overlay

[Ernest Van Hoecke]

The NAU8822 audio codec on the Toradex Verdin Development Board and
Apalis Evaluation Board V1.2 can combine its two loudspeaker outputs
into a Bridge Tied Load (BTL) output. The overlay selecting this mode
only sets a property on the codec node, which both boards label
nau8822_1a independent of the module.

Instead of adding identical overlays for every module, rename the
merged Verdin iMX8M Mini overlay to imx-tdx-nau8822-btl.dtso and combine it
with the Verdin iMX8M Plus, Verdin iMX95, Lino iMX91, Lino iMX93 and
Apalis iMX8 device trees. The combined Verdin iMX8M Mini DTB keeps its
name.

Changes in v2:
- Split the BTL patch out of the Verdin iMX8M Plus overlay series, whose
  display overlays are deferred
- Share one overlay instead of adding an iMX8M Plus copy (Frank)
- Also replace the Verdin iMX95 and Apalis iMX8 BTL overlays posted in

  https://lore.kernel.org/r/20261001-v1-apalis-colibri-imx8-dtsos-v1-1-21881dc324c1@xxxxxxxxxxx
