This series also contains device-tree bindings for msm DP driver. It also contains Makefile and Kconfig changes to compile msm DP driver. The block diagram of DP driver is shown below: +-------------+ |DRM FRAMEWORK| +------+------+ | +----v----+ | DP DRM | +----+----+ | +----v----+ +------------+| DP +----------++------+ + +---+| DISPLAY |+---+ | | | + +-+-----+-+ | | | | | | | | | | | | | | | | | | | | | | | | v v v v v v v +------+ +------+ +---+ +----+ +----+ +---+ +-----+ | DP | | DP | |DP | | DP | | DP | |DP | | DP | |PARSER| | HPD | |AUX| |LINK| |CTRL| |PHY| |POWER| +--+---+ +---+--+ +---+ +----+ +--+-+ +-+-+ +-----+ | | | +--v---+ +v-----v+ |DEVICE| | DP | | TREE | |CATALOG| +------+ +---+---+ | +---v----+ |CTRL/PHY| | HW | +--------+ Changes in v7: - Modify cover letter description and fix title. - Introduce dp-controller.yaml for common bindings across SOC - Rename dp-sc7180.yaml to dp-controller-sc7180.yaml for SC7180 bindings - Rename compatible string to qcom,sc7180-dp - Add assigned-clocks and assigned-clock-parents properties in bindings - Remove redundant code from driver - Extend series to include HPD detection logic Changes in v8: - Add MDSS AHB clock in bindings - Replace mode->vrefresh use with drm_mode_vrefresh API - Remove redundant aux config code from parser and aux module - Assign default max lanes if data-lanes property is not available - Fix use-after-free during DP driver remove -
