+description: |
+  Broadcom Broadband SoC supports High Speed SPI master controller since the
+  early MIPS based chips such as BCM6328 and BCM63268.  This initial rev 1.0
+  controller was carried over to recent ARM based chips, such as BCM63138,
+  BCM4908 and BCM6858. The old MIPS based chip should continue to use the
+  brcm,bcm6328-hsspi compatible string. 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. This can
+  terminate the transaction to some SPI devices prematurely. The issue can be
+  worked around by either the controller's prepend mode or using the dummy chip
+  select workaround. Driver automatically picks the suitable mode based on
+  transfer type so it is transparent to the user.
+
+  The newer SoCs such as BCM6756, BCM4912 and BCM6855 include an updated SPI
+  controller rev 1.1 that add the capability to allow the driver to control chip
+  select explicitly. This solves the issue in the old controller.
