From 269ecf03a5b32b0d1de1f60a4b86b75c0521053f Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Thu, 10 Mar 2016 15:34:16 -0800 Subject: [PATCH] mtd: brcmnand: Add support for v6.2 controllers Document and match the brcm,brcmnand-v6.2 compatible string, the controller has a register layout identical to the v6.0 version and supports prefetch. Update the command shift logic to account for v6.2 controller which are the first ones to use a shift of 0 (6.1 used a shift of 24).
