[PATCHv3 5/6] net: stmmac: socfpga: Use shared System Manager driver

From: thor . thayer
Date: Mon Jan 28 2019 - 17:12:25 EST


From: Thor Thayer <thor.thayer@xxxxxxxxxxxxxxx>

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.

v2 No change to code. Update commit message.
v3 Remove the unused syscon.h header.
