Ingenic DRM bridge_atomic_enable proposal

ingenic_drm_bridge_atomic_enable allows the CRTC to be enabled after panels have slept out, and before their display is turned on, solving a graphical bug on the newvision nv3502c.

Also add ingenic_drm_bridge_atomic_disable to balance it out.

I understand that this is added because the panel registers are write-only and read as zero, and it is needed for regmap_{clear,set}_bits to work.

This information should definitely be added to the commit message.

If you can add it inline here, and I'll update the commit message when applying the patch.

Following the introduction of bridge_atomic_enable in the ingenic drm driver, the crtc is enabled between .prepare and .enable, if it exists. Add it so the backlight is only enabled after the crtc is, to avoid graphical issues.

As we're moving the "sleep in" command out of the init sequence into .enable for the ABT, we need to switch the regmap cache to REGCACHE_FLAT to be able to use regmap_set_bits, given this panel registers are write-ony and read as 0.

Sorry I meant "sleep out" not "sleep in" obviously

Quoted 27 lines · Christophe Branchereau

Following the introduction of bridge_atomic_enable in the ingenic drm driver, the crtc is enabled between .prepare and .enable, if it exists. Add it so the backlight is only enabled after the crtc is, to avoid graphical issues.

As we're moving the "sleep in" command out of the init sequence into .enable for the ABT, we need to switch the regmap cache to REGCACHE_FLAT to be able to use regmap_set_bits, given this panel registers are write-ony and read as 0.

Didn't Sam acked it?

Hello,

v5 :

- this set doesn't include the nv3052c bindings doc anymore, as it's already applied

- nv3052c panel driver : removed empty lines, proceed to turn it off even is sleeping in fails instead of stopping there

- abt panel : switched to REGCACHE_FLAT so we can disable sleep mode in .enable with regmap_set_bits() instead of doing it at init time

- ingenic-drm-drv : added ingenic_drm_bridge_atomic_disable to balance out ingenic_drm_bridge_atomic_enable

Tested working on the rg350m and rg280m

Christophe Branchereau (3):
drm/ingenic : add ingenic_drm_bridge_atomic_enable and disable drm/panel: Add panel driver for NewVision NV3052C based LCDs drm/panel : innolux-ej030na and abt-y030xx067a : add .enable and
.disable
