Subject: [PATCH AUTOSEL 5.9 05/35] arm64: dts: amlogic: meson-g12: use the G12A specific dwmac compatible

From: Martin Blumenstingl <martin.blumenstingl@...glemail.com>

[ Upstream commit 1fdc97ae450ede2b4911d6737a57e6fca63b5f4a ]

We have a dedicated "amlogic,meson-g12a-dwmac" compatible string for the
Ethernet controller since commit 3efdb92426bf4 ("dt-bindings: net:
dwmac-meson: Add a compatible string for G12A onwards").
Using the AXG compatible string worked fine so far because the
dwmac-meson8b driver doesn't handle the newly introduced register bits
for G12A. However, once that changes the driver must be probed with the
correct compatible string to manage these new register bits.
