Subject: [PATCHv2] i.MX6-SabreAuto: WEIM: add steering-gpios to set WEIM for NOR
Date: Thu, 15 Jan 2015 10:46:10 -0800	[thread overview]
Message-ID: <1421347571-9239-1-git-send-email-alison_chaiken@mentor.com> (raw)
In-Reply-To: <20150115075646.GM23940-bIcnvbaLZ9MEGnE8C9+IrQ@public.gmane.org>

From: Alison Chaiken <alison_chaiken-nmGgyN9QBj3QT0dZR+AlfA@public.gmane.org>

The EIM switch of the i.MX6 SabreAuto CPU cards can connect pins
EIM_D18 and EIM_D30 of the CPU to either the parallel NOR or to other
peripherals.  Add a steering-gpios property to the imx6qdl-sabreauto
device-tree to allow boot-time configuration of the EIM.  Use GPIO5,
pin 4 to connect EIM_D18 to the NOR so the do_map_probe() function
correctly detects the CFI.

Support is not added for boot-time steering of EIM_D30 due to present
inability to test.
