Hi Laurent and all,
I have prototyped the RZ/G2L DU driver with a library that shares the common code
between R-Car and RZ/G2L Du drivers.
Looks like the total patches is now more than 20.
So planning to send the same with batches of 2-3 small series in order to make
review simpler.
Cheers,
Biju
> Subject: [PATCH v4 0/2] Add RZ/G2L Display support
>
> RZ/G2L LCD controller composed of Frame compression Processor(FCPVD),
> Video signal processor (VSPD) and Display unit(DU). The output of LCDC
> is connected to Display parallel interface and MIPI link video
> interface.

> This patch series aims to add basic display support on RZ/G2L SMARC EVK

> v3->v4:
> * Changed compatible name from renesas,du-r9a07g044->renesas,r9a07g044-
> du
> * started using same compatible for RZ/G2{L,LC}
> * Removed rzg2l_du_group.h and struct rzg2l_du_group
> * Renamed __rzg2l_du_group_start_stop->rzg2l_du_start_stop
> * Removed rzg2l_du_group_restart
> * Updated rzg2l_du_crtc_set_display_timing
> * Removed mode_valid callback.
> * Updated rzg2l_du_crtc_create() parameters
> * Updated compatible
> * Removed RZG2L_DU_MAX_GROUPS
> V2->v3:
> * Added new bindings for RZ/G2L DU
> * Removed indirection and created new DRM driver based on R-Car DU
> v1->v2:
> * Based on [1], all references to 'rzg2l_lcdc' replaced with 'rzg2l_du'
> * Updated commit description for bindings
> * Removed LCDC references from bindings
> * Changed clock name from du.0->aclk from bindings
> * Changed reset name from du.0->du from bindings
> * Replaced crtc_helper_funcs->rcar_crtc_helper_funcs
> * Updated macro DRM_RZG2L_LCDC->DRM_RZG2L_DU
> * Replaced rzg2l-lcdc-drm->rzg2l-du-drm
> * Added forward declaration for struct reset_control

> RFC->v1:
> * Changed minItems->maxItems for renesas,vsps.
> * Added RZ/G2L LCDC driver with special handling for CRTC reusing
> most of RCar DU code
> * Fixed the comments for num_rpf from rpf's->RPFs/ and vsp->VSP.
