| Subject: [PATCH 257/286] drm: Add data transmission order bus flag |
| |
| The flags indicate whether data is transmitted LSB to MSB or MSB to LSB |
| on the bus. |
| |
| The exact meaning is bus-type dependent. For instance, for LVDS buses |
| the flags indicate whether the seven data bits transmitted in a clock |
| pulse are sent in normal order (MSB to LSB, slots 0 to 6) or reverse |
| order (LSB to MSB, slots 6 to 0). |
