Re: [PATCH 11/13] ARM: dts: add support for WeTek Hub and WeTek Play2

23 Mar 2023

On 23/03/2023 07:54, Christian Hewitt wrote:
...
Import the dts files from linux-amlogic/for-next (Linux 6.4-rc1) and
add the old PHY reset bindings for dwmac to the u-boot.dtsi until we
support the new bindings in the PHY node. Without this the PHY is not
functional in u-boot or Linux.
