These patches were tested both in drm-exynos-next and linux-next (with drm-exynos-next merged in) and it solves the infinite loop and parent device lock deadlock. It was tested with Ajay's DP patches applied. A tree based on drm-exynos-next can be found here:
https://git.kernel.org/cgit/linux/kernel/git/padovan/drm-exynos.git/log/?h=d...
The first patch reverts the other tries to fix this problem.
The second patch is a revert and fixes a regression with the subdriver probe function getting a NULL drvdata and thus failing drm_exynos_init()
The third patch is a port to drm-exynos-next of Javier patches that moves the platform driver registration to init.
