The patch

   dt-binding: spi: Document Macronix controller bindings

has been applied to the spi tree at

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

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

+Macronix SPI controller Device Tree Bindings
+--------------------------------------------
+
+Required properties:
+- compatible: should be "mxicy,mx25f0a-spi"
+- #address-cells: should be 1
+- #size-cells: should be 0
+- reg: should contain 2 entries, one for the registers and one for the direct
+       mapping area
+- reg-names: should contain "regs" and "dirmap"
+- interrupts: interrupt line connected to the SPI controller
+- clock-names: should contain "ps_clk", "send_clk" and "send_dly_clk"
+- clocks: should contain 3 entries for the "ps_clk", "send_clk" and
+	  "send_dly_clk" clocks
+
+Example:
+
+	spi@43c30000 {
+		compatible = "mxicy,mx25f0a-spi";
+		reg = <0x43c30000 0x10000>, <0xa0000000 0x20000000>;
+		reg-names = "regs", "dirmap";
+		clocks = <&clkwizard 0>, <&clkwizard 1>, <&clkc 18>;
+		clock-names = "send_clk", "send_dly_clk", "ps_clk";
+		#address-cells = <1>;
+		#size-cells = <0>;
+
+		flash@0 {
+			compatible = "jedec,spi-nor";
+			reg = <0>;
+			spi-max-frequency = <25000000>;
+			spi-tx-bus-width = <4>;
+			spi-rx-bus-width = <4>;
+		};
