Hi Geert-san, Laurent-san.
We have tested Linux stable v4.5 on Koelsch board.
This Linux version v4.5, we can not show an image or picture on HDMI
display.
(There is no problem on v4.5-rc3, could show an image on HDMI display
normally)
And we found a patch between v4.5-rc3 and v4.5 that causing of this issue.
The patch is "b26a719 gpio: rcar: Add Runtime PM handling for interrupts."
Tested by: Xuan Truong Nguyen <nx-truong@xxxxxxxxxxx>.
In case of "git revert" this patch, we can show image on display normally.
Please have a look at this patch and fixing this issue.
Best regards,
Jinso/Cao Minh Hiep.
