This adds the thermal sensor driver for the Broadcom BCM2711 SoC,

This looks good, I just have a couple of nits that you can address since
the binding needs to be re-spun, see below, in any case:

Here we use %ld

+		dev_err(dev, "could not register sensor: %d\n", ret);

and here we do an implicit cast into int, thus using %d, could we just
make both consistent and use %d?
