Add bindings for Snapdragon DisplayPort controller driver.
Changes in V2: Provide details about sel-gpio
Changes in V4: Provide details about max dp lanes Change the commit text
Changes in V5: moved dp.txt to yaml file
Changes in v6: - Squash all AUX LUT properties into one pattern Property - Make aux-cfg[0-9]-settings properties optional - Remove PLL/PHY bindings from DP controller dts - Add DP clocks description - Remove _clk suffix from clock names - Rename pixel clock to stream_pixel - Remove redundant bindings (GPIO, PHY, HDCP clock, etc..) - Fix indentation - Add Display Port as interface of DPU in DPU bindings and add port mapping accordingly.
Chages in v7: - Add dp-controller.yaml file common between multiple SOC - Rename dp-sc7180.yaml to dp-controller-sc7180.yaml - change compatible string and add SOC name to it. - Remove Root clock generator for pixel clock - Add assigned-clocks and assigned-clock-parents bindings - Remove redundant properties, descriptions and blank lines - Add DP port in DPU bindings - Update depends-on tag in commit message and rebase change accordingly
Changes in v8: - Add MDSS AHB clock in bindings
