20   use the brcm,bcmbca-hsspi-v1.0 as part of its compatible string list as
23   This rev 1.0 controller has a limitation that can not keep the chip select line
24   active between the SPI transfers within the same SPI message. This can
25   terminate the transaction to some SPI devices prematurely. The issue can be
27   select workaround. Driver automatically picks the suitable mode based on
32   select explicitly. This solves the issue in the old controller.
