From 99ac86187d0b5b4134a75847c3e7886cfd61c351 Mon Sep 17 00:00:00 2001 From: Samuel Holland Date: Thu, 7 May 2020 18:10:51 -0500 Subject: [PATCH] net: sun8i_emac: Add support for the H6 variant The H6 EMAC is very similar to the H3 variant, except that it uses the same pinmux as R40. Add support for it.
