Changes done during conversion:

* added a description, lifting and adapting the limitation sentence from
  brcm,bcm63xx-hsspi.yml
* added appropriate compatibles for all SoCs that are supported by
  bcm63xx/bmips

      commit: 0e19118ab24beea86dac16ce3c550c47d31f777d

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark

+description: |
+  Broadcom "Low Speed" SPI controller found in many older MIPS based Broadband
+  SoCs.
+
+  This 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
+  the controller's prepend mode.

-Binding for Broadcom BCM6348/BCM6358 SPI controller
-
-Required properties:
-- compatible: must contain one of "brcm,bcm6348-spi", "brcm,bcm6358-spi".
-- reg: Base address and size of the controllers memory area.
-- interrupts: Interrupt for the SPI block.
-- clocks: phandle of the SPI clock.
-- clock-names: has to be "spi".
-- #address-cells: <1>, as required by generic SPI binding.
-- #size-cells: <0>, also as required by generic SPI binding.
-
-Optional properties:
-- num-cs: some controllers have less than 8 cs signals. Defaults to 8
-  if absent.
-
-Child nodes as per the generic SPI binding.
-
-Example:
-
-	spi@10000800 {
-		compatible = "brcm,bcm6368-spi", "brcm,bcm6358-spi";
-		reg = <0x10000800 0x70c>;
-
-		interrupts = <1>;
-
-		clocks = <&clkctl 9>;
-		clock-names = "spi";

-		num-cs = <5>;
