From 63015d73f345a9196e910b84c3f329a22556bcf4 Mon Sep 17 00:00:00 2001 From: Roger Quadros Date: Thu, 7 Apr 2016 13:25:39 +0300 Subject: [PATCH] ARM: dts: am335x: Provide NAND ready pin On these boards NAND ready pin status is avilable over GPMC_WAIT0 pin. For NAND we don't use GPMC wait pin monitoring but get the NAND Ready/Busy# status using GPIOlib. GPMC driver provides the WAIT0 pin status over GPIOlib. Read speed increases from 7869 KiB/ to 8875 KiB/s and write speed was unchanged at 5100 KiB/s. Measured using mtd_speedtest.ko on am335x-evm.
