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.
The output from DSI is connected to ADV7535.
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 and created new CRTC/DRM driver
specific to RZ/G2L.
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.
* Fixed checkpatch warnings
* Updated rcar_du_vsp_plane_setup()
* Updated rcar_du_fb_create() for the pixel fmt error.
* Updated commit description for RZ/G2UL driver patch
* Updated Kconfig
* Replaced drm_fb_cma_helper->drm_gem_dma_helper
* Updated header files.
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
[1] https://patchwork.kernel.org/project/linux-renesas-soc/patch/20220312084205.31462-2-biju.das.jz@xxxxxxxxxxxxxx/
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.
