Subject: [RESEND PATCHv4 5/6] net: stmmac: socfpga: Use shared System Manager driver
Date:   Mon, 11 Mar 2019 17:18:07 -0500
Message-Id: <1552342688-6663-6-git-send-email-thor.thayer@linux.intel.com>
In-Reply-To: <1552342688-6663-1-git-send-email-thor.thayer@linux.intel.com>

From: Thor Thayer <thor.thayer@linux.intel.com>

The ARM64 System Manager requires a different method of reading
the System Manager than ARM32. A new System Manager driver was
created to steer ARM32 System Manager calls to regmap_mmio and
ARM64 System Manager calls to the new access method.

Convert from syscon to the shared System Manager driver so that
both ARM64 and ARM32 are supported.
