Subject: [PATCH v7 09/12] PCI: qcom: Add ipq8064 rev2 variant
Date: Mon, 15 Jun 2020 23:06:05 +0200	[thread overview]
Message-ID: <20200615210608.21469-10-ansuelsmth@gmail.com> (raw)
In-Reply-To: <20200615210608.21469-1-ansuelsmth@gmail.com>

Ipq8064-v2 have tx term offset set to 0. Introduce this variant to permit
