If you don't want to enable it, just don't define it at all. The code just checks for the presence of this property, so defining it as zero means you will enable it. >> >>> + gpmc,mux-add-data = <0>; >> >> This should be either 1 or 2. > > In arch/arm/mach-omap2/gpmc.h it gets set by this: > #define GPMC_CONFIG1_MUXTYPE(val) ((val & 3) << 8) > > but the TRM for AM/DM37x as well as the TRM for Omap35x says: > > |9 MUXADDDATA Enables the Address and data multiplexed protocol (Reset RW 0x- > | value is CS0MUXDEVICE input pin sampled at IC reset for > | CS0 and 0 for CS1-7) > | 0x0: Non Multiplexed attached device > | 0x1: Address and data multiplexed attached device > > From u-boot I got 0x00001800 for register GPMC_CONFIG1. So Bit 9 is 0. > Why should I set it here to non zero? It should be either 1 or 2, or you should not define it. So if the bit is zero from the u-boot configuration, just leave it out this property. Setting to 0 is probably ok if you don't want to have address-data multiplexing, but it is also pointless. >>> + gpmc,device-nand = <1>; >> >> This is a boolean parameter so you don't need the "= <0>". > > The nand here is attached by 16 lines.
