[PATCH v1 0/9] drm/bridge: ps8640 and ti-sn65dsi86 updates

[Sam Ravnborg]

Add a new macro DRM_BRIDGE_STATE_OPS that can be used to
assign atomic_reset and atomic_{duplicate,destroy}_state to
the default implementations. They will be valid in most cases.

Add a drm variant of media-bus-format.h to hold a single
function to get the bpc from the bus format.

Also add a small drm_atomic_helper_bridge_dsi_input_bus_fmt helper.

Update ti-sn65dsi86 to support atomic and NO_CONNECTOR.
The NO_CONNECTOR support was from Rob Clark - I just rebased it.
To support NO_CONNECTOR use the newly introduced function to
lokk up bpc from the bus format.

Update parade-ps8640 to support atomic. To do this just migrate
to the atomic variants of the operations and add the few mandatry
missing callbacks.

A few of the patches are migrated from a patchset I posted several
months ago and I decided to add them here for now, which explains
why there is a v4 of a patch in a v1 submission.

For the output bus fmt stuff I did what I think is correct - but
as I have paged out all my memory of this it may be all wrong.

The code builds - but needs testing.

I was temped to move bridge helpers to a new drm_bridge_helper.c
but that will wait until next time.
