Required properties: - compatible: Must be "qcom,mdss-dsi" - hw-config: Specifies the DSI host setup configuration "hw-config" = "single_dsi" "hw-config" = "dual_dsi" "hw-config" = "split_dsi" - ranges: The standard property which specifies the child address space, parent address space and the length. - vdda-supply: Phandle for vreg regulator device node. Bus Scaling Data: - qcom,msm-bus,name: String property describing MDSS client. - qcom, msm-bus,num-cases: This is the number of bus scaling use cases defined in the vectors property. This must be set to <2> for MDSS DSI driver where use-case 0 is used to remove BW votes from the system. Use case 1 is used to generate bandwidth requestes when sending command packets. - qcom,msm-bus,num-paths: This represents number of paths in each bus scaling usecase. This value depends on number of AXI master ports dedicated to MDSS for particular chipset. - qcom,msm-bus,vectors-KBps: A series of 4 cell properties, with a format of (src, dst, ab, ib) which is defined at Documentation/devicetree/bindings/arm/msm/msm_bus.txt. DSI driver should always set average bandwidth (ab) to 0 and always use instantaneous bandwidth(ib) values. Optional properties: - vcca-supply: Phandle for vcca regulator device node. - qcom,<type>-supply-entries: A node that lists the elements of the supply used by the a particular "type" of DSI modulee. The module "types" can be "core", "ctrl", and "phy". Within the same type, there can be more than one instance of this binding, in which case the entry would be appended with the supply entry index. e.g. qcom,ctrl-supply-entry@0 -- qcom,supply-name: name of the supply (vdd/vdda/vddio) -- qcom,supply-min-voltage: minimum voltage level (uV) -- qcom,supply-max-voltage: maximum voltage level (uV) -- qcom,supply-enable-load: load drawn (uA) from enabled supply -- qcom,supply-disable-load: load drawn (uA) from disabled supply -- qcom,supply-ulp-load: load drawn (uA) from supply in ultra-low power mode -- qcom,supply-pre-on-sleep: time to sleep (ms) before turning on -- qcom,supply-post-on-sleep: time to sleep (ms) after turning on -- qcom,supply-pre-off-sleep: time to sleep (ms) before turning off -- qcom,supply-post-off-sleep: time to sleep (ms) after turning off - pll-src-config Specified the source PLL for the DSI link clocks: "PLL0" - Clocks sourced out of DSI PLL0 "PLL1" - Clocks sourced out of DSI PLL1 This property is only valid for certain DSI hardware configurations mentioned in the "hw-config" binding above. For example, in split_dsi config, the clocks can only be sourced out of PLL0. For dual_dsi, both PLL would be active. For single DSI, it is possible to select either PLL. If no value is specified, the default value for single DSI is set as PLL0. - qcom,mmss-ulp-clamp-ctrl-offset: Specifies the offset for dsi ulps clamp control register. - qcom,mmss-phyreset-ctrl-offset: Specifies the offset for dsi phy reset control register. - qcom,dsi-clk-ln-recovery: Boolean which enables the clk lane recovery mdss-dsi-ctrl is a dsi controller device which is treated as a subnode of the mdss-dsi device.
