dt-bindings: net: mediatek: add support for MediaTek MT7623 and MT7622 SoC
The patch adds the supplements in the dt-binding document for MediaTek MT7622 SoC with extra SGMII system controller and relevant clock consumers listed as the requirements for those SoCs equipped with the SGMII circuit. Also, add the missing binding information for MT7623 SoC here which relies on the fallback binding of MT2701. Signed-off-by: Sean Wang <sean.wang@mediatek.com> Signed-off-by: David S.
