-* ARM Primecell Peripherals
-
-ARM, Ltd. Primecell peripherals have a standard id register that can be used to
-identify the peripheral type, vendor, and revision. This value can be used for
-driver matching.
-
-Required properties:
-
-- compatible : should be a specific name for the peripheral and
- "arm,primecell". The specific name will match the ARM
- engineering name for the logic block in the form: "arm,pl???"
-
-Optional properties:
-
-- arm,primecell-periphid : Value to override the h/w value with
-- clocks : From common clock binding. First clock is phandle to clock for apb
- pclk. Additional clocks are optional and specific to those peripherals.
-- clock-names : From common clock binding. Shall be "apb_pclk" for first clock.
-- dmas : From common DMA binding. If present, refers to one or more dma channels.
-- dma-names : From common DMA binding, needs to match the 'dmas' property.
- Devices with exactly one receive and transmit channel shall name
- these "rx" and "tx", respectively.
-- pinctrl-<n> : Pinctrl states as described in bindings/pinctrl/pinctrl-bindings.txt
-- pinctrl-names : Names corresponding to the numbered pinctrl states
-- interrupts : one or more interrupt specifiers
-- interrupt-names : names corresponding to the interrupts properties
-
-Example:
-
-serial@fff36000 {
- compatible = "arm,pl011", "arm,primecell";
- arm,primecell-periphid = <0x00341011>;
-
- clocks = <&pclk>;
- clock-names = "apb_pclk";
-
- dmas = <&dma-controller 4>, <&dma-controller 5>;
- dma-names = "rx", "tx";
-
- pinctrl-0 = <&uart0_default_mux>, <&uart0_default_mode>;
- pinctrl-1 = <&uart0_sleep_mode>;
- pinctrl-names = "default","sleep";
-
- interrupts = <0 11 0x4>;
-};
