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.
|
|
|
|
Optional properties:
|
|
- label: A string used to describe the controller used.
|
|
- qcom,supply-names: A list of strings that lists the names of the
|
|
regulator supplies.
|
|
- qcom,supply-min-voltage-level: A list that specifies minimum voltage level
|
|
of supply(ies) mentioned above. This list maps
|
|
in the order of the supply names listed above.
|
|
- qcom,supply-max-voltage-level: A list that specifies maximum voltage level of
|
|
supply(ies) mentioned above. This list maps in
|
|
the order of the supply names listed above.
|
|
- qcom,supply-peak-current: A list that specifies the peak current that will
|
|
be drawn from the supply(ies) mentioned above. This
|
|
list maps in the order of the supply names listed above.
|
|
|
|
|
|
Example:
|
|
mdss_dsi0: qcom,mdss_dsi@fd922800 {
|
|
