Subject: dt-bindings: spi: Move the bindings for the FSL QSPI driver
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=80261459804507a349daf754d6e5d835bb8578ae;p=openwrt%2Fstaging%2Fblogic.git

dt-bindings: spi: Move the bindings for the FSL QSPI driver

Move the documentation of the old SPI NOR driver to the place of the new
SPI memory interface based driver.

-* Freescale Quad Serial Peripheral Interface(QuadSPI)
-
-Required properties:
-  - compatible : Should be "fsl,vf610-qspi", "fsl,imx6sx-qspi",
-		 "fsl,imx7d-qspi", "fsl,imx6ul-qspi",
-		 "fsl,ls1021a-qspi"
-		 or
-		 "fsl,ls2080a-qspi" followed by "fsl,ls1021a-qspi",
-		 "fsl,ls1043a-qspi" followed by "fsl,ls1021a-qspi"
-  - reg : the first contains the register location and length,
-          the second contains the memory mapping address and length
-  - reg-names: Should contain the reg names "QuadSPI" and "QuadSPI-memory"
-  - interrupts : Should contain the interrupt for the device
-  - clocks : The clocks needed by the QuadSPI controller
-  - clock-names : Should contain the name of the clocks: "qspi_en" and "qspi".
-
-Optional properties:
-  - fsl,qspi-has-second-chip: The controller has two buses, bus A and bus B.
-                              Each bus can be connected with two NOR flashes.
-			      Most of the time, each bus only has one NOR flash
-			      connected, this is the default case.
-			      But if there are two NOR flashes connected to the
-			      bus, you should enable this property.
-			      (Please check the board's schematic.)
-  - big-endian : That means the IP register is big endian
-
-Example:
-
-qspi0: quadspi@40044000 {
-	compatible = "fsl,vf610-qspi";
-	reg = <0x40044000 0x1000>, <0x20000000 0x10000000>;

-	interrupts = <0 24 IRQ_TYPE_LEVEL_HIGH>;
-	clocks = <&clks VF610_CLK_QSPI0_EN>,

-	clock-names = "qspi_en", "qspi";
-
-	flash0: s25fl128s@0 {
-		....
-	};
-};
