The DSI PHY block acts as a clock provider, creating - 2 clocks: A byte clock (index 0), and a pixel clock (index 1). -- power-domains: Should be <&mmcc MDSS_GDSC>. -- clocks: Phandles to device clocks. See [1] for details on clock bindings. -- clock-names: the following clocks are required: - * "iface" - * "ref" (only required for new DTS files/entries) - For 28nm HPM/LP, 28nm 8960 PHYs: -- vddio-supply: phandle to vdd-io regulator device node - For 20nm PHY: -- vddio-supply: phandle to vdd-io regulator device node -- vcca-supply: phandle to vcca regulator device node - For 14nm PHY: -- vcca-supply: phandle to vcca regulator device node - For 10nm PHY: -- vdds-supply: phandle to vdds regulator device node - -Optional properties: -- qcom,dsi-phy-regulator-ldo-mode: Boolean value indicating if the LDO mode PHY - regulator is wanted. -- qcom,mdss-mdp-transfer-time-us: Specifies the dsi transfer time for command mode - panels in microseconds. Driver uses this number to adjust - the clock rate according to the expected transfer time. - Increasing this value would slow down the mdp processing - and can result in slower performance. - Decreasing this value can speed up the mdp processing, - but this can also impact power consumption. - As a rule this time should not be higher than the time - that would be expected with the processing at the - dsi link rate since anyways this would be the maximum - transfer time that could be achieved. - If ping pong split is enabled, this time should not be higher - than two times the dsi link rate time. - If the property is not specified, then the default value is 14000 us. - -[1] Documentation/devicetree/bindings/clock/clock-bindings.txt -[2] Documentation/devicetree/bindings/graph.txt -[3] Documentation/devicetree/bindings/media/video-interfaces.txt -[4] Documentation/devicetree/bindings/display/panel/ - -Example: - dsi0: dsi@fd922800 { - compatible = "qcom,mdss-dsi-ctrl"; - qcom,dsi-host-index = <0>; - interrupt-parent = <&mdp>; - interrupts = <4 0>; - reg-names = "dsi_ctrl"; - reg = <0xfd922800 0x200>; - power-domains = <&mmcc MDSS_GDSC>; - clock-names = - "bus", - "byte", - "core", - "core_mmss", - "iface", - "mdp_core", - "pixel"; - clocks = - <&mmcc MDSS_AXI_CLK>, - <&mmcc MDSS_BYTE0_CLK>, - <&mmcc MDSS_ESC0_CLK>, - <&mmcc MMSS_MISC_AHB_CLK>, - <&mmcc MDSS_AHB_CLK>, - <&mmcc MDSS_MDP_CLK>, - <&mmcc MDSS_PCLK0_CLK>; - - assigned-clocks = - <&mmcc BYTE0_CLK_SRC>, - <&mmcc PCLK0_CLK_SRC>; - assigned-clock-parents = - <&dsi_phy0 0>, - <&dsi_phy0 1>; - - vdda-supply = <&pma8084_l2>; - vdd-supply = <&pma8084_l22>; - vddio-supply = <&pma8084_l12>; - - phys = <&dsi_phy0>; - phy-names ="dsi-phy"; - - qcom,dual-dsi-mode; - qcom,master-dsi; - qcom,sync-dual-dsi; - - qcom,mdss-mdp-transfer-time-us = <12000>; - - pinctrl-names = "default", "sleep"; - pinctrl-0 = <&dsi_active>; - pinctrl-1 = <&dsi_suspend>; - - ports { - #address-cells = <1>; - #size-cells = <0>; - - port@0 { - reg = <0>; - dsi0_in: endpoint { - remote-endpoint = <&mdp_intf1_out>; - }; - }; - - port@1 { - reg = <1>; - dsi0_out: endpoint { - remote-endpoint = <&panel_in>; - data-lanes = <0 1 2 3>; - }; - }; - }; - - panel: panel@0 { - compatible = "sharp,lq101r1sx01"; - reg = <0>; - link2 = <&secondary>; - - power-supply = <...>; - backlight = <...>; - - port { - panel_in: endpoint { - remote-endpoint = <&dsi0_out>; - }; - }; - }; - }; - - dsi_phy0: dsi-phy@fd922a00 { - compatible = "qcom,dsi-phy-28nm-hpm"; - qcom,dsi-phy-index = <0>; - reg-names = - "dsi_pll", - "dsi_phy", - "dsi_phy_regulator"; - reg = <0xfd922a00 0xd4>, - <0xfd922b00 0x2b0>, - <0xfd922d80 0x7b>; - clock-names = "iface"; - clocks = <&mmcc MDSS_AHB_CLK>; - #clock-cells = <1>; - vddio-supply = <&pma8084_l12>; - - qcom,dsi-phy-regulator-ldo-mode; - };
