| 13 | description: | |
| 14 | This binding file is a collection of the DSI panels that |
| 15 | are usually driven in command mode. If no backlight is |
| 16 | referenced via the optional backlight property, the DSI |
| 17 | panel is assumed to have native backlight support. |
| 18 | The panel may use an OF graph binding for the association |
| 19 | to the display, or it may be a direct child node of the |
| 20 | display. |

| 39 | vddi-supply: |
| 40 | description: |
| 41 | Display panels require power to be supplied. While several panels need |
| 42 | more than one power supply with panel-specific constraints governing the |
| 43 | order and timings of the power supplies, in many cases a single power |
| 44 | supply is sufficient, either because the panel has a single power rail, or |
| 45 | because all its power rails can be driven by the same supply. In that case |
| 46 | the vddi-supply property specifies the supply powering the panel as a |
| 47 | phandle to a regulator. |
| 48 | |
| 49 | vpnl-supply: |
| 50 | description: |
| 51 | When the display panel needs a second power supply, this property can be |
| 52 | used in addition to vddi-supply. Both supplies will be enabled at the |
| 53 | same time before the panel is being accessed. |
