Subject: [PATCH v2 1/3] PCI: imx: No-op imx6_setup_phy_mpll() on i.MX7D
Date: Wed,  5 Dec 2018 23:35:43 -0800	[thread overview]
Message-ID: <20181206073545.10967-2-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_setup_phy_mpll()
is applicable.
