Hi Marta,

Yes that didn't help since the driver thinks that the eDP panel is already ON,
but may be its turning on and off many times generating multiple HPD pulses. So
just disregard the patch.

One more thing I want you to try is in the igt test itself (kms_flip.c), in the
run_test_on_crtc_set() function, I see that kmstest_unset_all_crtcs() is called
which actually powers off the panel. Could you add a usleep() call here to
sleep for a few ms before actually doing a modeset where it will power the eDP
panel back on.
This might give some time to the panel power sequencer to stabilize before
turning it back on.

This is one of the tests, I have few more things to debug in mind and I will
send details regarding the second test soon.
