Merge tag 'spi-v6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi

Pull spi updates from Mark Brown:
 "This has been a fairly quiet release for SPI, though it is likely that
  the next release will have some big changes as there's some
  preparatory work for multiple chip select support gone in - the rest
  of the code is on the list but will need to be rebased onto -rc1.
  Otherwise there's a couple of new tunables for chip select timings,
  some new devices and smaller device specific updates and fixes.

   - Support for configuring the hold and minimum inactive times for
     chip selects.

   - Beginnings of support for supporting devices which have multiple
     chip selects on a single device.

   - Support for newer Broadcom HSSPI and Intel controllers, Silicon
     Labs EM3581 and SI3210"

+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.

-Binding for Broadcom BCM6328 High Speed SPI controller

-Required properties:
-- compatible: must contain of "brcm,bcm6328-hsspi".
-- reg: Base address and size of the controllers memory area.
-- interrupts: Interrupt for the SPI block.
-- clocks: phandles of the SPI clock and the PLL clock.
-- clock-names: must be "hsspi", "pll".
-- #address-cells: <1>, as required by generic SPI binding.
-- #size-cells: <0>, also as required by generic SPI binding.
