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.

Just note that I thought since exynos5800 is very similar with exynos5420 so I didn't ask Chander to test the series on exynos5800 based board...Just asked to test with Nico's mcpm series. BTW, unfortunately I have no exynos5800-peach-pi... > 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? > Yes I think so. As you can see in exynos5800.dtsi, it is including exynos5420. > For testing, I tried today's linux-next and arm-soc/for-next. > Hmm...why is the problem happened at last? Not at that time? :( I need to figure it out...
