+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>;
|
|
+
|
|
+ #address-cells = <1>;
|
|
+ #size-cells = <0>;
|
|
+ };
