Subject: [PATCH 0/5] Add ethernet support for RPi5

Hello,

Few patches to enable support of ethernet on RPi5.

 - first patch is setting upper 32bits of DMA RX ring buffer in case of
   RX queue corruption.
 - second patch is adding a new compatible in cdns,macb yaml document
 - third patch adds compatible and configuration for raspberrypi,rp1-gem
 - forth and fifth patches are adding and enabling ethernet DT node on
   RPi5.

Comments are welcome!

Regards,
~Stan
