Benoit Cousson 661db794eb of/irq: Add interrupts-names property to name an irq resource
Add a interrupts-names property to allow the possibility to provide a name
to any interrupts entries.  If the name is available, use it to name the
resource, otherwise keep the device full name.

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";
reg = <0x4a064000 0x800>, <0x4a064800 0x200>,
<0x4a064c00 0x200>;
reg-names = "config", "ohci", "ehci";
interrupts = <14>, <15>;
interrupt-names = "ohci", "ehci";
};
