Add clock binding information for primecell peripherals. For most, a clock input name of "apb_pclk" is required. Any primecell peripherals which are different will need to be documented separately.

* 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.
|
|
|
|
Example:
|
|
|
|
serial@fff36000 {
|
|
compatible = "arm,pl011", "arm,primecell";
|
|
arm,primecell-periphid = <0x00341011>;
|
|
clocks = <&pclk>;
|
|
clock-names = "apb_pclk";
|
|
|
|
};
