Hi,
When booting v4.12-rc5 on Nokia N900, omapdrm fails to probe and there is no display.
Bisected to:
a09d2bc1503508c17ef3a71c6b1905e3660f3029 is the first bad commit commit a09d2bc1503508c17ef3a71c6b1905e3660f3029 Author: Peter Ujfalusi peter.ujfalusi@ti.com Date: Tue May 3 22:08:01 2016 +0300
drm/omap: Use omapdss_stack_is_ready() to check that the display stack is up
Instead of 'guessing' based on aliases of the status of the DSS drivers, use the new interface to check that all needed drivers are loaded. In this way we can be sure that all needed drivers are loaded so it is safe to continue the probing of omapdrm. This method will allow the omapdrm to be probed 'headless', without outputs.

Reverting the commit seems to fix the issue.
