Subject: [PATCH net-next v5 0/6] net: dsa: microchip: Add KSZ8463 switch support

From: Tristram Ha <tristram.ha@...rochip.com>

This series of patches is to add KSZ8463 switch support to the KSZ DSA
driver.

v5
- Use separate SPI read and write functions for KSZ8463
- remove inline keyword inside ksz8.c

v4
- Fix a typo in ksz8_reg.h
- Fix logic in ksz8463_r_phy()

v3
- Replace cpu_to_be16() with swab16() to avoid compiler warning
- Disable PTP function in a separate patch

v2
- Break the KSZ8463 driver code into several patches for easy review
- Replace ntohs with cpu_to_be16
