Revert the HACKs and fix the issue in DSI driver

[RobertCNelson]

Awesome @ravi-rahul testing right now!

Hi @RobertCNelson

This PR needs these device tree changes https://github.com/beagleboard/BeagleBoard-DeviceTrees/pull/64

Please test with device tree changes in above PR

[RobertCNelson]

ah so close... DisplayPorts works, but my RPI 7-inch isn't going beyond display init (no logo or console..) merging into staging branch to debug...

[RobertCNelson]

Building artifacts.. https://git.beagleboard.org/RobertCNelson/ti-linux-kernel-dev/-/jobs/6712

[RobertCNelson]

test build out...

On the panel system, @ravi-rahul what's the best way to see what it tried todo..

debian@BeagleBone:~/$ #panel
debian@BeagleBone:~/$ dmesg | grep dss

[ravi-rahul]

for me it's working, with test build artifacts

[ravi-rahul]

dmesg | grep -i RPi dmesg | grep -i Rasp

[ravi-rahul]

sudo apt install libdrm-tests modetest -M tidss

[ravi-rahul]

can you please share the log of modetest -M tidss on your setup

grabing another card.. (with xfce installed).. this was just a test console image, that had always shown a prompt..

Regards,

[RobertCNelson]

[RobertCNelson]

usb on the back is powered, but this is how i have it setup, and how the screen looked prior to the patches..

[ravi-rahul]

setup looks correct, not sure what is the issue

[RobertCNelson]

so... with a fresh xfce image...

i don't know why basic console broke..

[ravi-rahul]

got it

[RobertCNelson]

i'll push it out.. not sure why console is broken, but x works..

[ravi-rahul]

Thanks !
