   4 Subject: [PATCH] arm64: dts: allwinner: A64: Restore EMAC changes
   5
   6 The original dwmac-sun8i DT bindings have some issue on how to handle
   7 integrated PHY and was reverted in last RC of 4.13.
   8 But now we have a solution so we need to get back that was reverted.
   9
  10 This patch restore arm64 DT about dwmac-sun8i for A64
  11 This reverts commit 87e1f5e8bb4b ("arm64: dts: allwinner: Revert EMAC changes")
