2025-07-04drm/msm/dpu: move features out of the DPU_HW_BLK_INFODmitry Baryshkov
As features bits are now unused by some of the hardware block configuration structures, remove the 'features' from the DPU_HW_BLK_INFO so that it doesn't get included into hw info structures by default and only include it when necessary.

2024-11-03drm/msm/dpu: rework documentation commentsDmitry Baryshkov
Unfortunately the tooling doesn't check documents placed before funciton prototypes. Such comments frequently become outdated, miss several params, etc. Move documentation for the functions to be placed before the actual function body, allowing 'make W=1' to actually check these comments and report an error.

2023-12-05drm/msm/dpu: use devres-managed allocation for HW blocksDmitry Baryshkov
Use devm_kzalloc to create HW block structure. This allows us to remove corresponding kfree and drop all dpu_hw_*_destroy() functions as well as dpu_rm_destroy(), which becomes empty afterwards.

2023-05-22drm/msm/dpu: Pass catalog pointers in RM to replace for-loop ID lookupsMarijn Suijten
The Resource Manager already iterates over all available blocks from the catalog, only to pass their ID to a dpu_hw_xxx_init() function which uses an _xxx_offset() helper to search for and find the exact same catalog pointer again to initialize the block with, fallible error handling and all. Instead, pass const pointers to the catalog entries directly to these _init functions and drop the for loops entirely, saving on both readability complexity and unnecessary cycles at boot.

2022-07-06drm/msm/dpu: merge base_off with blk_off in struct dpu_hw_blk_reg_mapDmitry Baryshkov
There is little point in keeping a separate MDP address and block offset in this struct. Merge them to form a new blk_addr field used for all register access.

We (nearly) do not use the length field from struct dpu_hw_blk_reg_map, so we can drop it safely.

2022-07-04drm/msm/dpu: remove hwversion field from data structuresDmitry Baryshkov
The driver should not depend on hw revision for detecting features. Instead it should use features from the hw catalog. Drop the hwversion field from struct dpu_mdss_cfg and struct dpu_hw_blk_reg_map.
