This path series aims to add support for RZ/G2L DU DRM driver. 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.

https://patchwork.kernel.org/project/linux-renesas-soc/list/?series=742810 v10->v11: * Replaced CONFIG_DRM_RCAR_VSP->CONFIG_VIDEO_RENESAS_VSP1 for building rzg2l_du_vsp driver. * Dropped "rzg2l_du_regs.h" instead the relevant definitions defined in .c file. * Dropped setting ditr5 based on latest HW manual 1.3.0/1.4.0 * Updated the comment for auto clear. * Replaced writel()->rzg2l_du_write() in rzg2l_du_start_stop(). * Dropped CRC related functions as it does not have DISCOM. * Replaced the variable possible_crtcs->possible_outputs in struct rzg2l_du_output_routing. * Updated DMA_BIT_MASK from 40->32. * Dropped unneeded struct drm_bridge from rzg2l_du_drv.h. * Dropped colour keying support as it doesn't have planes. * Added only RGB formats in rzg2l_du_format_infos. * Dropped chroma planes from rzg2l_du_fb_create(). * Updated the comment for max_pitch in rzg2l_du_fb_create(). * Dropped possible_crtcs check in

ARM64 dependency from Kconfig. * Sorted the configs alphabetically in Kconfig. * Dropped DRM_RCAR_VSP config option and make DRM_RZG2L_DU depend on VIDEO_RENESAS_VSP1. * On rzg2l_du_crtc_set_display_timing() replaced the setting of parent clk rate with dclk rate. * Added rzg2l_du_write() wrapper function. * Updated the comment atomic_begin->atomic_flush. * Dropped .atomic_check and .atomic_begin callback * Renamed __rzg2l_du_crtc_plane_atomic_check->__rzg2l_du_vsp_plane_atomic _check and moved it to rzg2l_du_vsp.c * Added struct clk in rzg2l_du_crtc.h * Dropped the variables mmio_offset,index,vblank_lock,vblank_wait, vblank_count from struct rzg2l_du_crtc. * Replaced the macro to_rzg2l_crtc with static inline functions. * Dropped the unneeded header files clk.h, io.h, mm.h, pm.h, slab.h, wait.h and drm_managed.h from rzg2l_du_drv.c. * Replaced DRM_INFO->drm_info * Dropped the callbacks prime_handle_to_fd, prime_fd_to_handle and gem_prime_mmap. * Replaced the callback remove->remove_new. * Dropped header file wait.h and added forward declarations struct clk and rzg2l_du_device from rzg2l_du_drv.h. * Dropped the dsi and dpad0_source variables from struct rzg2l_du_device. * Replaced the macro to_rzg2l_encoder with static inline functions. * Dropped header files dma-buf.h and wait.h from rzg2l_du_kms.c. * Dropped struct sg_table and added the scatterlist.h header file in rzg2l_du_vsp.h * Added container_of.h header file, forward declarations struct device and struct rzg2l_du_device in rzg2l_du_vsp.h. v8->v9: * Added Rb tag from Laurent and Acked-by tag from Kieran for patch#1. * Added Rb tag from Laurent and Geert for patch#3. * Dropped reset_control_assert() from error patch for rzg2l_du_crtc_get() as suggested by Philipp Zabel. * Added Rb tag from Laurent oatch#5. * Updated MAINTAINERS entries for common parts(Makefile and Kconfig). v7->v8: * Moved rcar-du and shmobile DRM drivers to renesas specific vendor directory. * Fixed the typo vsp2->du in RZ/V2L DU bindings patch. * Added Rb tag from Rob for RZ/V2L DU bindings patch. * Dropped RCar du lib and created RZ/G2L DU DRM driver by creating rz_du folder. * Updated MAINTAINERS entries. 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. * Added patch #2 for binding support for RZ/V2L DU * Added patch #4 for driver support for RZ/V2L DU * Added patch #5 for SoC DTSI support for RZ/G2L DU * Added patch #6 for SoC DTSI support for RZ/V2L DU * Added
