Subject: [patch 1/2] kirkwood: allow machines to register RnB line with mtd driver
Date: Fri, 30 Apr 2010 00:12:54 +0100 [thread overview]
Message-ID: <20100429231313.519744154@fluff.org.uk> (raw)
In-Reply-To: 20100429231253.465019575@fluff.org.uk
[-- Attachment #1: slinux/arm/kirkwood/allow-mtd-ready-not-busy-registration.patch --]
[-- Type: text/plain, Size: 1855 bytes --]
Add a kirkwood_nand_init_rnb() call to allow boards which
have RnB line detection to register this instead of a
static delay.
