I'm curious what platforms this is expected to work on, and where it's
been tested.

I tried it on exynos5800-peach-pi (chromebook2) and it hangs up (no
kernel messages) shortly after the driver loads, and never finishes to
boot.

I needed an extra compatible entry for the 5800 in the driver for the
driver to load, which suggests it hasn't been tested on 5800, but at
least in theory, this should be compatible with the 542x, right?

For testing, I tried today's linux-next and arm-soc/for-next.
