| Beniamino Galvani | 318fd49 | 2014-09-20 15:29:17 +0200 | [diff] [blame] | 8 | |
| Martin Blumenstingl | 6aee159 | 2016-09-06 23:38:43 +0200 | [diff] [blame] | 9 | - compatible: Depending on the platform this should be one of: |
| 10 | - "amlogic,meson6-dwmac" |
| 11 | - "amlogic,meson8b-dwmac" |
| 12 | - "amlogic,meson-gxbb-dwmac" |

| Martin Blumenstingl | 6aee159 | 2016-09-06 23:38:43 +0200 | [diff] [blame] | 14 | Additionally "snps,dwmac" and any applicable more |
| 15 | detailed version number described in net/stmmac.txt |
| 16 | should be used. |

| Martin Blumenstingl | 6aee159 | 2016-09-06 23:38:43 +0200 | [diff] [blame] | 18 | - reg: The first register range should be the one of the DWMAC |
| 19 | controller. The second range is is for the Amlogic specific |
| 20 | configuration (for example the PRG_ETHERNET register range |
| 21 | on Meson8b and newer) |

| Martin Blumenstingl | 6aee159 | 2016-09-06 23:38:43 +0200 | [diff] [blame] | 23 | Required properties on Meson8b and newer: |
| 24 | - clock-names: Should contain the following: |
| 25 | - "stmmaceth" - see stmmac.txt |
| 26 | - "clkin0" - first parent clock of the internal mux |
| 27 | - "clkin1" - second parent clock of the internal mux |
