Broadcom "Low Speed" SPI controller found in many older MIPS based Broadband
|
|
SoCs.
|
|
|
|
This controller has a limitation that can not keep the chip select line active
|
|
between the SPI transfers within the same SPI message. This can terminate the
|
|
transaction to some SPI devices prematurely. The issue can be worked around by
|
|
the controller's prepend mode.
