Subject: dt-bindings: net: mediatek,net: allow irq names
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=23ac2a71bdbd5d12616d46f276b7a7a06e74a8c3;p=thirdparty%2Fkernel%2Flinux.git

dt-bindings: net: mediatek,net: allow irq names

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.
