[RFC PATCH net-next 5/6] microchip: lan865x: add driver support for Microchip's LAN865X MACPHY
From: Parthiban Veerasooran
Date: Fri Sep 08 2023 - 10:31:34 EST
The LAN8650/1 is designed to conform to the OPEN Alliance 10BASE‑T1x
MAC‑PHY Serial Interface specification, Version 1.1. The IEEE Clause 4
MAC integration provides the low pin count standard SPI interface to any
microcontroller therefore providing Ethernet functionality without
requiring MAC integration within the microcontroller. The LAN8650/1
operates as an SPI client supporting SCLK clock rates up to a maximum of
25 MHz. This SPI interface supports the transfer of both data (Ethernet
frames) and control (register access).
By default, the chunk data payload is 64 bytes in size. A smaller payload
data size of 32 bytes is also supported and may be configured in the
Chunk Payload Size (CPS) field of the Configuration 0 (OA_CONFIG0)
register. Changing the chunk payload size requires the LAN8650/1 be reset
and shall not be done during normal operation.
The Ethernet Media Access Controller (MAC) module implements a 10 Mbps
half duplex Ethernet MAC, compatible with the IEEE 802.3 standard.
10BASE-T1S physical layer transceiver integrated into the LAN8650/1. The
PHY and MAC are connected via an internal Media Independent Interface
(MII).
