The DU controller on RZ/G2L LCDC is similar to R-Car as it is
connected to VSPD. RCar DU lib is created for sharing kms, vsp and encoder
driver code between both RCar and RZ/G2L alike SoCs.
Tested this patch series on RZ/{G2M, G2L, G2LC} and RZ/V2L platforms.
v6->v7:
* Split DU lib and RZ/G2L du driver as separate patch series as
DU support added to more platforms based on RZ/G2L alike SoCs.
* Rebased to latest drm-tip.
v5->v6:
* Merged DU lib and RZ/G2L du driver in same patch series
* Rebased to latest drm-misc.
* Merged patch#1 to RZ/G2L Driver patch.
* Updated KConfig dependency from ARCH_RENESAS->ARCH_RZG2L.
* Optimized rzg2l_du_output_name() by removing unsupported outputs.
v4->v5:
* Added Rb tag from Rob for binding patch.
* Started using RCar DU libs(kms, vsp and encoder)
* Started using rcar_du_device, rcar_du_write, rcar_du_crtc,
rcar_du_format_info and rcar_du_encoder.
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.
