1 Qualcomm adreno/snapdragon MDP5 display controller
5 This is the bindings documentation for the Mobile Display Subsytem(MDSS) that
6 encapsulates sub-blocks like MDP5, DSI, HDMI, eDP etc, and the MDP5 display
7 controller found in SoCs like MSM8974, APQ8084, MSM8916, MSM8994 and MSM8996.
13 - reg: Physical base address and length of the controller's registers.
14 - reg-names: The names of register regions. The following regions are required:
17 - interrupts: The interrupt signal from MDSS.
18 - interrupt-controller: identifies the node as an interrupt controller.
19 - #interrupt-cells: specifies the number of cells needed to encode an interrupt
21 - power-domains: a power domain consumer specifier according to
22 Documentation/devicetree/bindings/power/power_domain.txt
23 - clocks: device clocks. See ../clocks/clock-bindings.txt for details.
24 - clock-names: the following clocks are required.
28 - #address-cells: number of address cells for the MDSS children. Should be 1.
29 - #size-cells: Should be 1.
30 - ranges: parent bus address space is the same as the child bus address space.
33 - clock-names: the following clocks are optional:
40 - reg: Physical base address and length of the controller's registers.
41 - reg-names: The names of register regions. The following regions are required:
43 - interrupts: Interrupt line from MDP5 to MDSS interrupt controller.
44 - interrupt-parent: phandle to the MDSS block
46 - clocks: device clocks. See ../clocks/clock-bindings.txt for details.
47 - clock-names: the following clocks are required.
52 - ports: contains the list of output ports from MDP. These connect to interfaces
53 that are external to the MDP hardware, such as HDMI, DSI, EDP etc (LVDS is a
54 special case since it is a part of the MDP block itself).
56 Each output port contains an endpoint that describes how it is connected to an
57 external interface. These are described by the standard properties documented
59 Documentation/devicetree/bindings/graph.txt
60 Documentation/devicetree/bindings/media/video-interfaces.txt
62 The availability of output ports can vary across SoC revisions:
64 For MSM8974 and APQ8084:
65 Port 0 -> MDP_INTF0 (eDP)
66 Port 1 -> MDP_INTF1 (DSI1)
67 Port 2 -> MDP_INTF2 (DSI2)
68 Port 3 -> MDP_INTF3 (HDMI)
71 Port 0 -> MDP_INTF1 (DSI1)
73 For MSM8994 and MSM8996:
74 Port 0 -> MDP_INTF1 (DSI1)
75 Port 1 -> MDP_INTF2 (DSI2)
76 Port 2 -> MDP_INTF3 (HDMI)
79 - clock-names: the following clocks are optional:
