[v2,0/4] Ingenic DRM bridge_atomic_enable proposal

Message

Hello, this is the v2 for my set of patches :

- use dev_err_probe() instead of dev_err() in the newvision panel
driver probe function

- add bindings documentation for the Leadtek ltk035c5444t

Cheers - Christophe

------------------------

Hello, this is a set of patches to allow the upstreaming of the
NV3052C panel found in the Anbernic RG350M mips gaming handheld.

It was never upstreamed so far due to a longstanding graphical
bug, which I propose to solve by introducing ingenic_drm_bridge_atomic_enable
in the drm driver so the CRTC can be enabled after the panel itself slept
out, and not before as it used to.

After the drm change, 2 of the existing panels have to be modified accordingly
to introduce missing .enable and .disable in their code.

Christophe Branchereau (4):
  drm/ingenic : add ingenic_drm_bridge_atomic_enable
  drm/panel: Add panel driver for NewVision NV3052C based LCDs
  drm/panel : innolux-ej030na and abt-y030xx067a : add .enable and
    .disable
  dt-bindings: display/panel: Add Leadtek ltk035c5444t
