ARM: dts: am335x: Disable wait pin monitoring for NAND
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] AM335x TRM: SPRUH73L: 7.1.3.3.12.2 NAND Device-Ready Pin Cc: Teresa Remmet <t.remmet@phytec.de> Cc: Ilya Ledvich <ilya@compulab.co.il> Cc: Yegor Yefremov <yegorslists@googlemail.com> Cc: Rostislav Lisovy <lisovy@gmail.com> Cc: Enric Balletbo i Serra <eballetbo@iseebcn.com> Signed-off-by: Roger Quadros <rogerq@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
