[PATCH v1 0/16] drm: panel related updates

[Sam Ravnborg]

The first 9 patches replaces direct use of the drm_panel
function pointers with their drm_panel_* counterparts.
The function pointers are only supposed to be used by
the drm_panel infrastructure and direct use are discouraged.

ili9322 is updated to handle bus_flags in get_modes like everyone else.
This is in preparation for a later patch series where controller
becomes an arugument to get_modes() and not like today where drm_panel
is attached to a controller.

The remaining patches move functionality to the drm_panel core that
today are repeated in many drivers.
As preparation for this the inline functions are moved to drm_panel.c
and kernel-doc is made inline.
panel-simple is updated to benefit from the additional infrastructure
and is an example for the simplifications that can be done.

The patchset has been tested on my embedded target,
and build tested.

Feedback welcome!

The "fix opencoded" patches are all independent and can be applied
out of order. They were kept here to keep panel related patches in one series.
