[PATCH 00/16] drm/atomic: Switch drm_private_obj to reset

[Maxime Ripard <mripard@kernel.org>]

Hi,

This series started from my work on the hardware state readout[1], and
was suggested by Dmitry[2].

This series deal with the fact that drm_private_obj (and thus bridges)
are not initialized using the same pattern than any other object. This
series solves that inconsistency by aligning it to what we're doing for
all the other objects.

This was tested on a TI SK-AM62, with three bridges.

Let me know what you think,
Maxime
