This series adds support to use devcoredump for DPU driver. It introduces the dpu_dbg module which assists in the capturing of register dumps during error scenarios. When a display related error happens, the dpu_dbg module captures all the relevant register dumps along with the snapshot of the drm atomic state and triggers a devcoredump.
changes in v2: - Fix kbot errors - Rename drm_atomic_print_state function and add kernel doc for it - Fix multiple dsi registration issue with dpu_dbg
Abhinav Kumar (4): drm: allow drm_atomic_print_state() to accept any drm_printer drm/msm/dpu: add support to dump dpu registers drm/msm: register the base address with dpu_dbg module drm/msm/dpu: add dpu_dbg points across dpu driver
