Subject: [PATCH v7 8/9] ARM: dts: dm8168-evm: ARM: dts: Disable wait pin monitoring for NAND
Date: Tue, 23 Feb 2016 18:37:24 +0200	[thread overview]
Message-ID: <1456245445-31824-9-git-send-email-rogerq@ti.com> (raw)
In-Reply-To: <1456245445-31824-1-git-send-email-rogerq@ti.com>

The NAND Ready/Busy# line is connected to GPMC_WAIT0 pin and
can't be used for wait state insertion for NAND I/O read/write.
So disable read/write wait monitoring as per Reference Manual's
suggestion [1].

[1] dm816x TRM: SPRUGX8C: 9.2.4.12.2 NAND Device-Ready Pin
