Testing this on the actual hardware, I have a deferred probe for the cm33
remoteproc, and that's because mu1 is disabled on the parent dtsi.
I am seeing this error on startup:
[ 19.076704] platform remoteproc-cm33: deferred probe pending: imx-rproc: failed to request tx mailbox channel
and then, every time a new device is registered (e.g., when connecting a
USB device):
[ 68.473051] remoteproc remoteproc0: releasing imx-rproc
Please consider adding:
&mu1 {
status = "okay";
};

You have a mixture of spaces and tabs in this block (probably inherited by
