Qualcomm Technologies Inc. adreno/snapdragon DSI output
DSI Controller:
Required properties:
- compatible:
* "qcom,mdss-dsi-ctrl"
- reg: Physical base address and length of the registers of controller
- reg-names: The names of register regions. The following regions are required:
* "dsi_ctrl"
- qcom,dsi-host-index: The ID of DSI controller hardware instance. This should
be 0 or 1, since we have 2 DSI controllers at most for now.
- interrupts: The interrupt signal from the DSI block.
- power-domains: Should be <&mmcc MDSS_GDSC>.
- clocks: device clocks
See Documentation/devicetree/bindings/clocks/clock-bindings.txt for details.
- clock-names: the following clocks are required:
* "bus_clk"
* "byte_clk"
* "core_clk"
* "core_mmss_clk"
* "iface_clk"
* "mdp_core_clk"
* "pixel_clk"
- vdd-supply: phandle to vdd regulator device node
- vddio-supply: phandle to vdd-io regulator device node
- vdda-supply: phandle to vdda regulator device node
- qcom,dsi-phy: phandle to DSI PHY device node
Optional properties:
- panel@0: Node of panel connected to this DSI controller.
See files in Documentation/devicetree/bindings/panel/ for each supported
panel.
- qcom,dual-panel-mode: Boolean value indicating if the DSI controller is
driving a panel which needs 2 DSI links.
- qcom,master-panel: Boolean value indicating if the DSI controller is driving
the master link of the 2-DSI panel.
- qcom,sync-dual-panel: Boolean value indicating if the DSI controller is
driving a 2-DSI panel whose 2 links need receive command simultaneously.
- interrupt-parent: phandle to the MDP block if the interrupt signal is routed
through MDP block
DSI PHY:
Required properties:
- compatible: Could be the following
* "qcom,dsi-phy-28nm-hpm"
* "qcom,dsi-phy-28nm-lp"
- reg: Physical base address and length of the registers of PLL, PHY and PHY
regulator
- reg-names: The names of register regions. The following regions are required:
* "dsi_pll"
* "dsi_phy"
* "dsi_phy_regulator"
- qcom,dsi-phy-index: The ID of DSI PHY hardware instance. This should
be 0 or 1, since we have 2 DSI PHYs at most for now.
- power-domains: Should be <&mmcc MDSS_GDSC>.
- clocks: device clocks
See Documentation/devicetree/bindings/clocks/clock-bindings.txt for details.
- clock-names: the following clocks are required:
* "iface_clk"
- vddio-supply: phandle to vdd-io regulator device node
