Subject: [PATCH v3 net-next 0/2] Adapt the sja1105 DSA driver to the SPI controller's transfer limits
Date: Fri, 21 May 2021 00:16:55 +0300 [thread overview]
Message-ID: <20210520211657.3451036-1-olteanv@gmail.com> (raw)
From: Vladimir Oltean <vladimir.oltean@nxp.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 v3:
- Avoid a signed vs unsigned issue in the interpretation of SIZE_MAX.
- Move the max transfer length checks to probe time, since nothing will
change dynamically.
Changes in v2:
Remove the driver's use of cs_change and send multiple, smaller SPI
messages instead of a single large one.
