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.
