Applied "spi: dt-bindings: Convert spi-gpio binding to json-schema" to the spi tree

[Mark Brown <broonie@xxxxxxxxxx>]

The patch

   spi: dt-bindings: Convert spi-gpio binding to json-schema

has been applied to the spi tree at

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi.git for-5.3

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

-SPI-GPIO devicetree bindings
-
-This represents a group of 3-n GPIO lines used for bit-banged SPI on dedicated
-GPIO lines.
-
-Required properties:
-
- - compatible: should be set to "spi-gpio"
- - #address-cells: should be set to <0x1>
- - ranges
- - sck-gpios: GPIO spec for the SCK line to use
- - miso-gpios: GPIO spec for the MISO line to use
- - mosi-gpios: GPIO spec for the MOSI line to use
- - cs-gpios: GPIOs to use for chipselect lines.
-             Not needed if num-chipselects = <0>.
- - num-chipselects: Number of chipselect lines. Should be <0> if a single device
-                    with no chip select is connected.
-
-Deprecated bindings:
-
-These legacy GPIO line bindings can alternatively be used to define the
-GPIO lines used, they should not be used in new device trees.
-
- - gpio-sck: GPIO spec for the SCK line to use
- - gpio-miso: GPIO spec for the MISO line to use
- - gpio-mosi: GPIO spec for the MOSI line to use
-
-Example:
-
-	spi {
-		compatible = "spi-gpio";
-		#address-cells = <0x1>;
-		ranges;
-
-		sck-gpios = <&gpio 95 0>;
-		miso-gpios = <&gpio 98 0>;
-		mosi-gpios = <&gpio 97 0>;
-		cs-gpios = <&gpio 125 0>;
-		num-chipselects = <1>;
-
-		/* clients */
-	};
