Kernel-4.18.0-80.el8_resource-names

Some properties contain an ordered list of 1 or more datum which are
normally accessed by index. However, some devices will have multiple
values which are more naturally accessed by name. Device nodes can
include a supplemental property for assigning names to each of the list
items. The names property consists of a list of strings in the same
order as the data in the resource property.

The following supplemental names properties are defined.

Resource Property Supplemental Names Property


reg reg-names
clocks clock-names
interrupts interrupt-names

Usage:

The -names property must be used in conjunction with the normal resource
property. If not it will be ignored.

Examples:

l4-abe {
compatible = “simple-bus”;
#address-cells = <2>;
#size-cells = <1>;
ranges = <0 0 0x48000000 0x00001000>, /* MPU path /
<1 0 0x49000000 0x00001000>; /
L3 path */
mcasp {
compatible = “ti,mcasp”;
reg = <0 0x10 0x10>, <0 0x20 0x10>,
<1 0x10 0x10>, <1 0x20 0x10>;
reg-names = “mpu”, “dat”,
“dma”, “dma_dat”;
interrupts = <11>, <12>;
interrupt-names = “rx”, “tx”;
};

timer {
    compatible = "ti,timer";
    reg = <0 0x40 0x10>, <1 0x40 0x10>;
    reg-names = "mpu", "dma";
};

};

usb {
compatible = “ti,usb-host”;

interrupt-names = “ohci”, “ehci”;
