The i2c client drivers are old styled. The i2c-probe function called by attach_adapter function returns -EOPNOTSUPP. This states adapter does not support SMBUS_QUICK command. Same driver on linux-omap-2.6.26 works well. The omap_i2c_func in i2c-omap.c driver doesn't seem to be returning this support. What changes have gone into i2c-omap driver that are causing i2c-probe function to return this error value? -- Best Regards Pramod
