| Subject: arm64: dts: renesas: r8a77965: Attach the SYS-DMAC to the IPMMU |
| |
| From: Magnus Damm <damm+renesas@opensource.se> |
| |
| [ Upstream commit 4d76ad7d9de05506f1ee9a7b22416440468be090 ] |
| |
| For R-Car M3-N hook up SYS-DMAC0, SYS-DMAC1 and SYS-DMAC2 to |
| IPMMU-DS0 and IPMMU-DS1 in same way as for R-Car M3-W. |
| This follows the R-Car Gen3 Rev.1.00 (April 2018) datasheet. |
