Subject: dt-bindings: net: dwmac-meson: Add the Ethernet clock input for
|
|
Meson6/8
|
|
|
|
The additional DWMAC register on Amlogic Meson6 and Meson8 SoCs take a
|
|
clock input (which is provided by the HHI clock controller). For RMII
|
|
mode this clock is derived from the RMII reference clock. Document this
|
|
clock input so the clock can be enabled when needed.
