Subject: [PATCH 2/3] PCI: imx: No-op imx6_pcie_reset_phy() on i.MX7D
Date: Sat, 17 Nov 2018 10:12:24 -0800 [thread overview]
Message-ID: <20181117181225.10737-3-andrew.smirnov@gmail.com> (raw)
In-Reply-To: <20181117181225.10737-1-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.
