    ARM: dts: am335x: Provide NAND ready pin · 63015d73
    Roger Quadros authored
    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.
