From: Jon Hunter Date: Mon, 25 Feb 2013 17:36:47 +0000 (-0600) Subject: ARM: OMAP2+: Convert NAND to retrieve GPMC settings from DT X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=acc79980c92ca9e8a39115b60ca832718a8156df;p=linux-beck.git ARM: OMAP2+: Convert NAND to retrieve GPMC settings from DT When booting with device-tree, retrieve GPMC settings for NAND from the device-tree blob. This will allow us to remove all static settings stored in the gpmc-nand.c in the future once the migration to device-tree is complete.
