Subject: [PATCH v1 05/16] mt76: mt7921: add MT7921_COMMON module
Date:   Wed, 15 Sep 2021 09:14:38 +0800

From: Sean Wang <sean.wang@mediatek.com>

This is a preliminary patch to introduce mt7921s support.

MT7921_COMMON module grouping bus independent objects the both mt7921e and
mt7921s can share with and have to rely on.
