[PATCH v1 0/3] arm64: dts: freescale: imx8mp-(verdin|toradex-smarc): Add HDMI audio support

[Francesco Dolcini]

From: Francesco Dolcini <francesco.dolcini@toradex.com>

Add support for HDMI audio on Verdin and Toradex SMARC iMX8M Plus boards, as
done in commit b21f87b8322f ("arm64: dts: imx8mp-evk: enable hdmi_pai device")
on the NXP i.MX8MP EVK board.

In addition a small cleanup on spurious comments.

[PATCH v1 2/3] arm64: dts: freescale: imx8mp-verdin: enable hdmi_pai device

[Francesco Dolcini]

From: Francesco Dolcini <francesco.dolcini@toradex.com>

Enable the hdmi_pai device on the various iMX8M Plus Verdin boards that
feature the related HDMI interface.

The hdmi_pai device, together with aud2htx module, hdmi_pai and hdmi
controller compose the HDMI audio pipeline.

See commit b21f87b8322f ("arm64: dts: imx8mp-evk: enable hdmi_pai
device") for the equivalent change on the NXP i.MX8MP EVK board.
