Subject: [PATCH net-next v2 1/5] net: dsa: microchip: add ksz9563 in ksz_switch_ops and select based on compatible string
Add KSZ9563 inside ksz_switch_chips structure with
port_nirq as 3. KSZ9563 use KSZ9893 switch parameters
but port_nirq count is 3 for KSZ9563 whereas 2 for
KSZ9893. Add KSZ9563 inside ksz_switch_chips as a separate
member and from device tree map compatible string into
KSZ9563 inside ksz_spi.c and ksz9477_i2c.c.
Global Chip ID 1 and 2 registers read value 9893, select
sku based on Global Chip ID 4 Register which read 0x1c
for KSZ9563.
