| Subject: [PATCH 026/286] arm64: dts: r8a7795: salvator-x: Set drive-strength |
| for ravb pins |
| MIME-Version: 1.0 |
| Content-Type: text/plain; charset=UTF-8 |
| Content-Transfer-Encoding: 8bit |
| |
| The EthernetAVB should not depend on the bootloader to setup correct |
| drive-strength values. Values for drive-strength where found by |
| examining the registers after the bootloader has configured the |
| registers and successfully used the EthernetAVB. |
