| Subject: ARM: shmobile: r8a73a4: add a DT node for the DMAC |
| |
| Add a DT node for the only system DMAC instance on r8a73a4. The RT DMAC |
| can be added later under the same multiplexer, because they can serve the |
| same slaves and use the same MID-RID values. Configuration data is |
| supplied to the driver, using a compatibility match string. |
