[PATCH v2 02/11] mfd: syscon: Add Atmel Matrix bus DT binding documentation
From: Boris Brezillon <hidden>
Date: 2014-11-05 16:01:37

Subsystem:
multifunction devices (mfd), open firmware and flattened device tree bindings, the rest · Maintainers:

The Matrix registers are provided to configure internal bus behavior on at91 SoCs. Some registers might be access by several drivers (e.g. to configure external memory bus timings), hence we declare this register set as a syscon device.
