Subject: [PATCH v2 2/3] PCI: imx: No-op imx6_pcie_reset_phy() on i.MX7D
Date: Wed, 5 Dec 2018 23:35:44 -0800 [thread overview]
Message-ID: <20181206073545.10967-3-andrew.smirnov@gmail.com> (raw)
In-Reply-To: <20181206073545.10967-1-andrew.smirnov@gmail.com>
PCIE PHY IP block on i.MX7D differs from the one used on i.MX6 family,
so none of the code in current implementation of imx6_pcie_reset_phy()
is applicable.
