kernel unable to access tmp421 and ds1307

[bradbishop]

Similar to #11, this seems to be a hangup for the kernel due to the move from 2013.07 to 2016.05.

On bmc boot the rtc and tmp421 sensor cannot be accessed:

rtc-ds1307: probe of 0-0068 failed with error -5
tmp421 2-004c: Could not read configuration register (-5)
tmp421: probe of 2-004c failed with error -5

Thanks for testing. I assume this is on Palmetto as well? Can you reproduce in Qemu?

We want these opened as kernel issues. We need the kernel handle poorly configured hardware.

The previous u-boot was adding an I2C driver which was doing a reset of the I2C controller.

Should we add such a reset in the machine setup in the kernel ?

@shenki - Do you want this moved to kernel? You can move it with 'zenhub' (or I can do it for you).

[shenki]

Yes, lets move this to the kernel

Issue moved to openbmc/linux #96 via ZenHub
