title: Devicetree bindings for the GMU attached to certain Adreno GPUs
maintainers:
- Rob Clark <robdclark@gmail.com>
description: |
These bindings describe the Graphics Management Unit (GMU) that is attached
to members of the Adreno A6xx GPU family. The GMU provides on-device power
management and support to improve power efficiency and reduce the load on
the CPU.

Qualcomm adreno/snapdragon MDP5 display controller
Description:
This is the bindings documentation for the Mobile Display Subsytem(MDSS) that
encapsulates sub-blocks like MDP5, DSI, HDMI, eDP etc, and the MDP5 display
controller found in SoCs like MSM8974, APQ8084, MSM8916, MSM8994 and MSM8996.
MDSS:
Required properties:
- compatible:
* "qcom,mdss" - MDSS
- reg: Physical base address and length of the controller's registers.
- reg-names: The names of register regions. The following regions are required:
* "mdss_phys"
* "vbif_phys"
- interrupts: The interrupt signal from MDSS.
- interrupt-controller: identifies the node as an interrupt controller.
- #interrupt-cells: specifies the number of cells needed to encode an interrupt
source, should be 1.
- power-domains: a power domain consumer specifier according to
Documentation/devicetree/bindings/power/power_domain.txt
- clocks: device clocks. See ../clocks/clock-bindings.txt for details.
- clock-names: the following clocks are required.
* "iface"
* "bus"
* "vsync"
- #address-cells: number of address cells for the MDSS children. Should be 1.
- #size-cells: Should be 1.
- ranges: parent bus address space is the same as the child bus address space.
Optional properties:
- clock-names: the following clocks are optional:
* "lut"
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:
