    imx6在使用时，编译的内核发现i2c系统好像没起来，内核部分打印信息如下[align=left]mc_pfuze 1-0008: recv failed!:-5,80 [/align][font=等线][size=10.5pt]mc_pfuze: probe of 1-0008 failed with error -1[/size][/font] [font=等线]上两句好像是电源问题[/font] [align=left]i2c-core: driver [isl29023] using legacysuspend method [/align][font=等线][size=10.5pt]i2c-core: driver [isl29023] using legacy resumemethod[/size][/font] [font=等线][size=10.5pt]查了i2c-core源码如下[/size][/font] [font=等线][size=10.5pt] [/size][/font][font=等线]if (driver->suspend)[/font] [font=等线] pr_warn("i2c-core: driver [%s] using legacy suspend method\n",[/font] [font=等线] driver->driver.name);[/font] [font=等线] if (driver->resume)[/font] [font=等线] pr_warn("i2c-core: driver [%s] using legacy resume method\n",[/font] [font=等线] driver->driver.name);[/font] [font=等线]想问一下什么情况下这个[/font][font=等线]driver->suspend、[/font][font=等线]driver->resume会生效，他生效代表什么意思[/font]
