7 title: Broadcom BCM6348/BCM6358 SPI controller
10   - Jonas Gorski <jonas.gorski@gmail.com>
13   Broadcom "Low Speed" SPI controller found in many older MIPS based Broadband
16   This controller has a limitation that can not keep the chip select line active
17   between the SPI transfers within the same SPI message. This can terminate the
18   transaction to some SPI devices prematurely. The issue can be worked around by
19   the controller's prepend mode.
