Since the card detect is active low, shouldn't the pin be pulled high to avoid
floating? Or is there an external pull up available on the board?

There's an external pull up resistor to vreg_s10b, so there shouldn't be
any reason to pull it internally as well.

Generally I ask people to add the missing regulator-allow-set-load,
but in case of the RPMh driver, should we also consider allowing LPM?

That's totally SoC-specific, modulo the CD pin which can have
its own separate node and label

You specified interconnects, but no bw values.. was that on purpose?
Other than these nits, lgtm
(generally, my dt sources don't even have sdhci to compare)

I prefer to avoid LPM and dynamic load management, because I don't think
we're doing a good enough job across the kernel to ensure we get back to
HPM when needed.
At some point this needs to be re-evaluated though.

That's ugly, but I see the symmetry to other -# vs -names

The drive-strength and bias properties are board specific. Also, at this
time the CRD is the only board I'm aware of having the SD-card slot.
I suggest that we move it out of here once there's another user...
