The recent ARM based chip is required to + use the brcm,bcmbca-hsspi-v1.0 as part of its compatible string list as + defined below to match the specific chip along with ip revision info. + + This rev 1.0 controller has a limitation that can not keep the chip select line + active between the SPI transfers within the same SPI message.
