Subject: [PATCH v2 net-next 0/2] Adapt the sja1105 DSA driver to the SPI controller's transfer limits

From: Vladimir Oltean <vladimir.oltean@....com>

This series changes the SPI transfer procedure in sja1105 to take into
consideration the buffer size limitations that the SPI controller driver
might have.

Changes in v2:
Remove the driver's use of cs_change and send multiple, smaller SPI
messages instead of a single large one.

Vladimir Oltean (2):
  net: dsa: sja1105: send multiple spi_messages instead of using
    cs_change
  net: dsa: sja1105: adapt to a SPI controller with a limited max
    transfer size
