15   Broadcom Broadband SoC supports High Speed SPI master controller since the
16   early MIPS based chips such as BCM6328 and BCM63268.  This initial rev 1.0
17   controller was carried over to recent ARM based chips, such as BCM63138,
18   BCM4908 and BCM6858. The old MIPS based chip should continue to use the
19   brcm,bcm6328-hsspi compatible string. The recent ARM based chip is required to
20   use the brcm,bcmbca-hsspi-v1.0 as part of its compatible string list as
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
30   The newer SoCs such as BCM6756, BCM4912 and BCM6855 include an updated SPI
