Subject: [PATCH] arm64: dts: allwinner: H5: Restore EMAC changes
|
|
|
|
The original dwmac-sun8i DT bindings have some issue on how to handle
|
|
integrated PHY and was reverted in last RC of 4.13.
|
|
But now we have a solution so we need to get back that was reverted.
|
|
|
|
This patch restore arm64 DT about dwmac-sun8i for H5
|
|
This reverts a part of commit 87e1f5e8bb4b ("arm64: dts: allwinner: Revert EMAC changes")
