Subject: [PATCH v2 09/10] devicetree: bindings: pci: add ipq8064 rev 2 variant to qcom,pcie
Date: Thu,  2 Apr 2020 14:11:46 +0200	[thread overview]
Message-ID: <20200402121148.1767-10-ansuelsmth@gmail.com> (raw)
In-Reply-To: <20200402121148.1767-1-ansuelsmth@gmail.com>

Document qcom,pcie-ipq8064-v2 needed to use different phy_tx0_term_offset.
In ipq8064 phy_tx0_term_offset is 7, in rev 2, ipq8065 and other SoC it's
set to 0 by default.
