Description:
|
||||
|
||||
Device tree bindings for MSM Mobile Display Subsystem(MDSS) that encapsulates
|
||||
sub-blocks like DPU display controller, DSI and DP interfaces etc.
|
||||
The DPU display controller is found in SDM845 SoC.
|
||||
|
||||
MDSS:
|
||||
Required properties:
|
||||
- compatible: "qcom,sdm845-mdss", "qcom,sc7180-mdss"
|
||||
- reg: physical base address and length of controller's registers.
|
||||
- reg-names: register region names. The following region is required:
|
||||
* "mdss"
|
||||
- power-domains: a power domain consumer specifier according to
|
||||
Documentation/devicetree/bindings/power/power_domain.txt
|
||||
- clocks: list of clock specifiers for clocks needed by the device.
|
||||
- clock-names: device clock names, must be in same order as clocks property.
|
||||
The following clocks are required:
|
||||
* "iface"
|
||||
* "bus"
|
||||
* "core"
|
||||
- interrupts: 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.
|
||||
- iommus: phandle of iommu device node.
|
||||
- #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.
|
||||
- interconnects : interconnect path specifier for MDSS according to
|
||||
Documentation/devicetree/bindings/interconnect/interconnect.txt. Should be
|
||||
2 paths corresponding to 2 AXI ports.
|
||||
- interconnect-names : MDSS will have 2 port names to differentiate between the
|
||||
2 interconnect paths defined with interconnect specifier.
|
||||
|
||||
Optional properties:
|
||||
- assigned-clocks: list of clock specifiers for clocks needing rate assignment
|
||||
- assigned-clock-rates: list of clock frequencies sorted in the same order as
|
||||
the assigned-clocks property.
|
||||
|
||||
MDP:
|
||||
Required properties:
|
||||
- compatible: "qcom,sdm845-dpu", "qcom,sc7180-dpu"
|
||||
- reg: physical base address and length of controller's registers.
|
||||
- reg-names : register region names. The following region is required:
|
||||
* "mdp"
|
||||
* "vbif"
|
||||
- clocks: list of clock specifiers for clocks needed by the device.
|
||||
- clock-names: device clock names, must be in same order as clocks property.
|
||||
The following clocks are required.
|
||||
* "bus"
|
||||
* "iface"
|
||||
* "core"
|
||||
* "vsync"
|
||||
- interrupts: interrupt line from DPU to MDSS.
|
||||
- ports: contains the list of output ports from DPU device. These ports connect
|
||||
to interfaces that are external to the DPU hardware, such as DSI, DP etc.
|
||||
|
||||
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:

Optional properties:

- assigned-clocks: list of clock specifiers for clocks needing rate assignment

the assigned-clocks property.
