net: phy: mchp: Add support for LAN8814 QUAD PHY (1623ad8e) · Commits · 戴 / test

LAN8814 is a low-power, quad-port triple-speed (10BASE-T/100BASETX/1000BASE-T) Ethernet physical layer transceiver (PHY). It supports transmission and reception of data on standard CAT-5, as well as CAT-5e and CAT-6, unshielded twisted pair (UTP) cables. LAN8814 supports industry-standard QSGMII (Quad Serial Gigabit Media Independent Interface) and Q-USGMII (Quad Universal Serial Gigabit Media Independent Interface) providing chip-to-chip connection to four Gigabit Ethernet MACs using a single serialized link (differential pair) in each direction. The LAN8814 SKU supports high-accuracy timestamping functions to support IEEE-1588 solutions using Microchip Ethernet switches, as well as customer solutions based on SoCs and FPGAs. The LAN8804 SKU has same features as that of LAN8814 SKU except that it does not support 1588, SyncE, or Q-USGMII with PCH/MCH. This adds support for 10BASE-T, 100BASE-TX, and 1000BASE-T, QSGMII link with the MAC. Signed-off-by:
