afaerber: runtime issue, I found the cause on Friday and have a fix. I'll do more testing on Monday and post the patch
<javier__>
afaerber: the problem was that the dp-controller dev node was not a consumer of the DISP1 power domain
<javier__>
so the "Unhandled fault: imprecise external abort" is caused by the exynos-dp driver trying to access the dp registers when the PD is disabled
<sjoerd`>
javier__: so the DISP1 power domain got turned off ....
<sjoerd`>
that ;)
<sjoerd`>
javier__: nice find :)
<javier__>
sjoerd`: exactly, it only affected exynos5420 because exynos5250 already had the dp controller as DISP1 consumer
<sjoerd`>
Wonder why that didn't show up on ramdisk boots
<javier__>
sjoerd`: and before the regulator supply lookup deferral patch, the exynos hdmi drm driver was probed before so the pd was already turned on
<javier__>
sjoerd`: good question
sjoerd` is now known as sjoerd
<sjoerd>
javier__: guess the ordering also happened to be different for ramdisk boots or somesuch?
<javier__>
sjoerd: I found another regression exposed by the regulator path btw, the WiFi chip is not enumerated in the SDIO bus anymore
<javier__>
sjoerd: could be, I have to check the logs
<javier__>
sjoerd: which reminds me that I've to write that wireless lava test ;)
<sjoerd>
:p
<javier__>
sjoerd: already posted the patch so I've one less thing on my TODO for monday :)
