From ba99112384db44ce2ef053d6289c488d719599b6 Mon Sep 17 00:00:00 2001 From: Boris Brezillon Date: Wed, 14 Jan 2015 17:21:56 +0100 Subject: mfd: syscon: Add Atmel SMC binding doc The SMC registers are used to configure Atmel EBI (External Bus Interface) to interface with standard memory devices (NAND, NOR, SRAM or specialized devices like FPGAs). Declare this memory region as a syscon, so that different drivers can configure the SMC interface (mostly timing configuration) according to their need.
