Re: [PATCH v2 0/6] Enable HDMI support on Exynos platforms

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,

I've applied v6 of the HDMI patchset (together with the patches the set
depends on) onto torvalds/master, but I'm seeing a lot of warnings
(coming from __clk_{unprepare,disable}) that seem to originate from the
fimc subsystem.

Since the patchset also changes PM domain handling (which shows up in
the log as well), I was wondering if this is related?

Full boot log here:
http://www.math.uni-bielefeld.de/~tjakobi/archive/clk_warnings.txt

That's the tree I'm currently using:
https://github.com/tobiasjakobi/linux-odroid/commits/odroid-3.19.y
(maybe I'm missing something here?)


With best wishes,
Tobias

PS: This is on a ODROID-X2.
