| Guidelines for new compatibles for SoC blocks/components. |
| When adding new compatibles in new bindings, use the format:: |
| renesas,SoC-IP |
| |
| For example:: |
| renesas,r8a77965-csi2 |
| |
| When adding new compatibles to existing bindings, use the format in the |
| existing binding, even if it contradicts the above. |
