Add a function to create amba_devices (i.e. primecell peripherals) from device tree nodes. The device tree scanning is done by the of_platform_populate() function which can call of_amba_device_create based on a match table entry. Nodes with a "arm,primecell-periphid" property can override the h/w peripheral id value. Based on the original work by Jeremy Kerr.

* 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 value for peripheral and "arm,primecell"
|
|
|
|
Optional properties:
|
|
|
|
- arm,primecell-periphid : Value to override the h/w value with
|
|
|
|
Example:
|
|
|
|
serial@fff36000 {
|
|
compatible = "arm,pl011", "arm,primecell";
|
|
arm,primecell-periphid = <0x00341011>;
|
|
};
