Subject: airoha: an7581: add switch ports interrups
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=788958880b66dd3f451d53801c8d25e5e6cfe1b8;p=thirdparty%2Fopenwrt.git

airoha: an7581: add switch ports interrups

The MT7531 has an incorrect interrupt number described in the DTS.
This commit also adds PHY interrupts. They work the same as on
the MT7988.

Tested on Gemtek W1700k.
