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.
