| Qualcomm mdss-dsi-ctrl |
| |
| mdss-dsi-ctrl is a dsi controller device which supports host controllers that |
| are compatable with MIPI display serial interface specification. |
| |
| Required properties: |
| - compatible: Must be "qcom,mdss-dsi-ctrl" |
| - cell-index: Specifies the controller used among the two controllers. |
| - reg: offset and length of the register set for the device. |
| - vdd-supply: Phandle for vdd regulator device node. |
| - vddio-supply: Phandle for vdd-io regulator device node. |
| - vdda-supply: Phandle for vreg regulator device node. |
| - qcom,mdss-fb-map: pHandle that specifies the framebuffer to which the |
| interface is mapped. |
| - qcom,mdss-mdp: pHandle that specifies the mdss-mdp device. |
| - qcom,platform-regulator-settings: An array of length 7 that specifies the PHY |
| regulator settings. |
| - qcom,platform-strength-ctrl: An array of length 2 that specifies the PHY |
| strengthCtrl settings. |
| - qcom,platform-bist-ctrl: An array of length 6 that specifies the PHY |
| BIST ctrl settings. |
| - qcom,platform-lane-config: An array of length 45 that specifies the PHY |
| lane configuration settings. |
| - qcom,dsi-pref-prim-pan: phandle that specifies the primary panel to be used |
| with the controller. |
| |
| Optional properties: |
| - label: A string used to describe the controller used. |
| |
| - qcom,platform-supply-entry<1..n>: A node that lists the elements of the supply. 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,platform-supply-entry1 |
| -- 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-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 |
| - qcom,platform-enable-gpio: Specifies the panel lcd/display enable gpio. |
| - qcom,platform-reset-gpio: Specifies the panel reset gpio. |
| - qcom,platform-te-gpio: Specifies the gpio used for TE. |
| - qcom,platform-mode-gpio: Select video/command mode of panel through gpio when it supports |
| both modes. |
