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.
|
|
|
