Subject: [PATCH v4 2/2] arm64: dts: imx8mm: Add support for emtrion emCON-MX8M Mini

From: Reinhold Mueller <[email protected]>

This patch adds support for the emtrion GmbH emCON-MX8M Mini modules.
They are available with NXP i.MX 8M Mini equipped with 2 or 4 GB Memory.

The devicetree imx8mm-emcon.dtsi is the common part providing all
module components and the basic support for the SoC. The support for the
avari baseboard in the developer-kit configuration is provided by the
emcon-avari dts files.

This version looks good to me.

One nit: you seem to use a single SPI chipselect, but you add two entries here.

Is the MX8MM_IOMUXC_ECSPI2_SS0_GPIO5_IO13 needed too?

Either way:

Yes, of course the emCON provides a connector connecting two slaves on the spi bus.

Please add Acked-by/Reviewed-by tags when posting new versions. However,
there's no need to repost patches *only* to add the tags. The upstream
maintainer will do that for acks received on the version they apply.

If a tag was not added on purpose, please state why and what changed.

In this case, then please pass gpio5 13 to the cs-gpios property too.
