[PATCH v1 0/2] drm/atmel-hlcdc: drop use of drm_irq mid-layer

[Sam Ravnborg]

Two small patches to drop the use of the drm irq mid-layer.
My atmel hlcdc target has stopped working - so unfortunately un-tested :-(
I picked up this to continue the work of Thomas Zimmermann.

[PATCH 1/1] drm: bridge: Mark deprecated operations in drm_bridge_funcs

[Sam Ravnborg]

drm_bridge_funcs includes several duplicated operations as atomic
variants has been added over time.
New bridge drivers shall use the atomic variants - mark the deprecated
operations to try to avoid usage in new bridge drivers.

Ignore this patch - I managed to chain the wrong patch to the cover
letter.

I tested this patch set on the 9x60ek board and unfortunately it causes 
errors.  The vbltest returns -1 and I also see the display get out of 
sync while testing with a gui application.


Regards,

Dan

Thanks a lot for the testing, I will take a look tomorrow and see if I
can figure out what is wrong.
