+Binding for Broadcom BCM6328 High Speed SPI controller
|
|
+
|
|
+Required properties:
|
|
+- compatible: must contain of "brcm,bcm6328-hsspi".
|
|
+- reg: Base address and size of the controllers memory area.
|
|
+- interrupts: Interrupt for the SPI block.
|
|
+- clocks: phandles of the SPI clock and the PLL clock.
|
|
+- clock-names: must be "hsspi", "pll".
|
|
+- #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@10001000 {
|
|
+ compatible = "brcm,bcm6328-hsspi";
|
|
+ reg = <0x10001000 0x600>;
|
|
+
|
|
+ interrupts = <29>;
|
|
+
|
|
+ clocks = <&clkctl 9>, <&hsspi_pll>;
|
|
+ clock-names = "hsspi", "pll";
|
|
+
|
|
+ num-cs = <2>;
|
|
+
|
|
+ #address-cells = <1>;
|
|
+ #size-cells = <0>;
|
|
+ };
