[Freedreno] [DPU PATCH v3 0/5] List of patches for DP drivers on SnapDragon

[Chandan Uddaraju]

These patches are to enable DisplayPort driver on SanpDragon.

These patches have dependency on clock driver changes that
provide DP clock support.

Changes in V2:
  Core Dp driver:
     -- Update copyright markings on all relevant files.
     -- Change pr_err() to DRM_ERROR()
     -- Use APIs directly instead of function pointers.
     -- Use drm_display_mode structure to store link parameters in the driver.
     -- Use macros for register definitions instead of hardcoded values in dp_catalog.c file.
     -- Replace writel_relaxed/readl_relaxed with writel/readl and remove memory barriers.
     -- Remove unnecessary NULL checks.
     -- Use drm helper functions for dpcd read/write.
     -- Use DRM_DEBUG_DP for debug msgs.
  DP PLL driver:
     -- Update copyright markings on all relevant files.
     -- Use DRM_DEBUG_DP for debug msgs.

Changes in V3:
  Core Dp Driver:
    -- Removed changes in dpu_io_util.[ch]
    -- Added locking around "is_connected" flag and removed atomic_set()
    -- Removed the argument validation checks in all the static functions
       except initialization functions and few API calls across msm/dp files
    -- Removed hardcoded values for register reads/writes
    -- Removed vreg related generic structures.
    -- Added return values where ever necessary.
    -- Updated dp_ctrl_on function.
    -- Calling the ctrl specific catalog functions directly instead of
       function pointers.
    -- Added seperate change that adds standard value in drm_dp_helper file.
    -- Added separate change in this list that is used to initialize
       displayport in DPU driver.
    -- Added change to use drm_dp_get_adjust_request_voltage() function.
