[PATCH v9 03/13] dt-bindings: net: mediatek,net: allow irq names

[Frank Wunderlich <linux@fw-web.de>]

From: Frank Wunderlich <frank-w@public-files.de>

In preparation for MT7988 and RSS/LRO allow the interrupt-names
property.
In this way driver can request the interrupts by name which is much
more readable in the driver code and SoC's dtsi than relying on a
specific order.

Frame-engine-IRQs (fe0..3):
MT7621, MT7628: 1 FE-IRQ
MT7622, MT7623: 3 FE-IRQs (only two used by the driver for now)
MT7981, MT7986: 4 FE-IRQs (only two used by the driver for now)

RSS/LRO IRQs (pdma0..3) additional only on Filogic (MT798x) with
count of 4. So all IRQ-names (8) for Filogic.

Set boundaries for all compatibles same as irq count.

v9:
- add interrupt-names minitems to 8 for filogic
  - mt7981 does not have a ethernet node yet
  - devicetree for mt7986 is updated later in this series
- small rephrase IRQ => FE-IRQ and mention total count of IRQs on Filogic.
- kept angelos RB because of small change, i hope it is ok :)

v8:
  - fixed typo in mt7621 section "interrupt-namess"
  - separated interrupt count from interrupt-names
  - rephrased description a bit to explain the "why"
v7: fixed wrong rebase
v6: new patch splitted from the mt7988 changes
