Convert the mdp5.txt into the yaml format. Changes to the existing (txt) schema:
- MSM8996 has additional "iommu" clock, define it separately
- Add new properties used on some of platforms:
- interconnects, interconnect-names
- iommus
- power-domains
- operating-points-v2, opp-table

-Qualcomm adreno/snapdragon MDP5 display controller
-
-Description:
-
-This is the bindings documentation for the MDP5 display
-controller found in SoCs like MSM8974, APQ8084, MSM8916, MSM8994 and MSM8996.
-
-MDP5:
-Required properties:
-- compatible:
- * "qcom,mdp5" - MDP5
-- reg: Physical base address and length of the controller's registers.
-- reg-names: The names of register regions. The following regions are required:
- * "mdp_phys"
-- interrupts: Interrupt line from MDP5 to MDSS interrupt controller.
-- clocks: device clocks. See ../clocks/clock-bindings.txt for details.
-- clock-names: the following clocks are required.
-- * "bus"
-- * "iface"
-- * "core"
-- * "vsync"
-- ports: contains the list of output ports from MDP. These connect to interfaces
- that are external to the MDP hardware, such as HDMI, DSI, EDP etc (LVDS is a
- special case since it is a part of the MDP block itself).
-
- Each output port contains an endpoint that describes how it is connected to an
- external interface. These are described by the standard properties documented
- here:
- Documentation/devicetree/bindings/graph.txt
- Documentation/devicetree/bindings/media/video-interfaces.txt
-
- The availability of output ports can vary across SoC revisions:
-
- For MSM8974 and APQ8084:
- Port 0 -> MDP_INTF0 (eDP)
- Port 1 -> MDP_INTF1 (DSI1)
- Port 2 -> MDP_INTF2 (DSI2)
- Port 3 -> MDP_INTF3 (HDMI)
-
- For MSM8916:
- Port 0 -> MDP_INTF1 (DSI1)
-
- For MSM8994 and MSM8996:
- Port 0 -> MDP_INTF1 (DSI1)
- Port 1 -> MDP_INTF2 (DSI2)
- Port 2 -> MDP_INTF3 (HDMI)
-
-Optional properties:
-- clock-names: the following clocks are optional:
- * "lut"
- * "tbu"
- * "tbu_rt"
-
-Example:
-
-/ {
- ...
