Subject: [PATCH] arm64: dts: allwinner: a64: pine64-plus: Add PHY regulator
|
||
|
|
delay
|
||
|
|
|
||
|
|
Depending on kernel and bootloader configuration, it's possible that
|
||
|
|
Realtek ethernet PHY isn't powered on properly. It needs some time
|
||
|
|
before it can be used.
|
||
|
|
|
||
|
|
Fix that by adding 100ms ramp delay to regulator responsible for
|
||
|
|
powering PHY.
|
||
|
|
|
||
|
|
Fixes: 94dcfdc77fc5 ("arm64: allwinner: pine64-plus: Enable dwmac-sun8i")
