Subject: Aw: [PATCH 09/13] PCI: mediatek: Advertise lack of MSI handling
Date: Mon, 1 Mar 2021 11:43:16 +0100
Message-ID: <trinity-b7e2cf18-f0e6-4d88-8a80-de6758b5a91f-1614595396771@3c-app-gmx-bap67> (raw)

tested full series on bananapi-r2 and r64

r2 (with mt7615) looks good.

on r64 (with atheros card WLE900VX) i see this while loading ath10k driver:

i guess it's a bug in ath10k driver or my r64 board (it is a v1.1 which has missing capacitors on tx lines).
Tried with an mt7612e, this seems to work without any errors.

so for mt7622/mt7623
