Hi Martin,

This looks good.

Only some minor comments:

Please pass pinctrl-names = "default"; prior to pinctrl-0. Please
check globally in this patch.

This should be active low instead.

After 8cdcd8aeee28 ("spi: imx/fsl-lpspi: Convert to GPIO descriptors")
you should a similar message as in the kernel log:

flash@0 enforce active low on chipselect handle

ecspigrp {

This seems to be not documented. It also misses the vendor.

Remove the comment, maybe?
