-Subject: [PATCH 2/8] spi/bcm63xx: make spi subsystem aware of message size
- limits
-
-The bcm63xx LS SPI controller does not allow manual control of the CS
-lines and will toggle it automatically before after sending data, so we
-are limited to messages that fit in the FIFO buffer. Since the CS lines
-aren't available as GPIOs either, we will need to make slave drivers
-aware of this limitation and handle it accordingly.
