1 * ARM Primecell Peripherals
3 ARM, Ltd. Primecell peripherals have a standard id register that can be used to
4 identify the peripheral type, vendor, and revision. This value can be used for
9 - compatible : should be a specific name for the peripheral and
10 "arm,primecell". The specific name will match the ARM
11 engineering name for the logic block in the form: "arm,pl???"
15 - arm,primecell-periphid : Value to override the h/w value with
16 - clocks : From common clock binding. First clock is phandle to clock for apb
17 pclk. Additional clocks are optional and specific to those peripherals.
18 - clock-names : From common clock binding. Shall be "apb_pclk" for first clock.
19 - dmas : From common DMA binding. If present, refers to one or more dma channels.
20 - dma-names : From common DMA binding, needs to match the 'dmas' property.
21 Devices with exactly one receive and transmit channel shall name
22 these "rx" and "tx", respectively.
23 - pinctrl-<n> : Pinctrl states as described in bindings/pinctrl/pinctrl-bindings.txt
24 - pinctrl-names : Names corresponding to the numbered pinctrl states
25 - interrupts : one or more interrupt specifiers
26 - interrupt-names : names corresponding to the interrupts properties
