Subject: [PATCH net-next v2 0/5] net: dsa: microchip: ksz_pwrite status check for lan937x and irq and error checking updates for ksz series

This patch series include following changes, 
- Add KSZ9563 inside ksz_switch_chips. As per current structure,
KSZ9893 is reused inside ksz_switch_chips structure, but since
there is a mismatch in number of irq's, new member added for KSZ9563
and sku detected based on Global Chip ID 4 Register. Compatible
string from device tree mapped to KSZ9563 for spi and i2c mode
probes.
- Assign device interrupt during i2c probe operation.
- Add error checking for ksz_pwrite inside lan937x_change_mtu. After v6.0,
ksz_pwrite updated to have return type int instead of void, and
lan937x_change_mtu still uses ksz_pwrite without status verification.
- Add port_nirq as 3 for KSZ8563 switch family.
- Use dev_err_probe() instead of dev_err() to have more standardized error
formatting and logging.

v1 -> v2:
- Removed regmap validation patch from the series, planning to take
  up in future after checking for any better approach and studying
  the actual need for this change.
- Resolved error reported in ksz8863_smi.c file.

Rakesh Sankaranarayanan (5):
  net: dsa: microchip: add ksz9563 in ksz_switch_ops and select based on
    compatible string
  net: dsa: microchip: add irq in i2c probe
  net: dsa: microchip: add error checking for ksz_pwrite
  net: dsa: microchip: ksz8563: Add number of port irq
  net: dsa: microchip: add dev_err_probe in probe functions
