Subject: [PATCH 2/5] mt76: introduce phys array in mt76_dev structure
Date:   Thu, 30 Jun 2022 23:41:13 +0200
Message-Id: <ceec0f68889842b499581d1085a5ac30ceaa2a8c.1656624320.git.lorenzo@kernel.org>

Introduce phys array in mt76_dev structure to reference mt76_phy
supported by the chipset. This is a preliminary patch to introduce
mt7990 chipset support.
