hwmon: (pmbus/isl68137): Update ISL68137 to upstream

2019-04-19T02:29:09+00:00

Apply differences from hwmon review to bring the driver code to the same point. There were some key differences regarding attribute placement from the review, beyond the normal cleanup. OpenBMC-Staging-Count: 1 Signed-off-by: Patrick Venture [AJ: Rework subject] Signed-off-by: Andrew Jeffery

pmbus: support for custom sysfs attributes

2019-04-19T02:27:48+00:00

This patch makes it possible to pass custom struct attribute_group array via the pmbus_driver_info struct so that those can be added to the attribute groups passed to hwmon_device_register_with_groups(). This makes it possible to register custom sysfs attributes by PMBUS drivers similar to how you can do this with most other busses/classes.

hwmon (occ): Add temp sensor value check

2019-04-18T01:45:19+00:00

The occ driver supports two formats for the temp sensor value. The OCC firmware for P8 supports only the first format, for which no range checking or error processing is performed in the driver. Inspecting the OCC sources for P8 reveals that OCC may send a special value 0xFFFF to indicate that a sensor read timeout has occurred, see https://github.com/open-power/occ/blob/master_p8/src/occ/cmdh/cmdh_fsp_cmds.c#L395 That situation wasn't handled in the driver. This patch adds invalid temp value check for the sensor data format 1 and handles it the same way as it is done for the format 2, where EREMOTEIO is reported for this case.

hwmon (occ): Prevent sysfs error attribute from returning error

2019-04-18T01:41:09+00:00

The error sysfs attribute returns the stored error state of the OCC and doesn't depend on the OCC poll response. Therefore, split the error attribute into it's own function to avoid failing out of the function if the poll response fails.

hwmon (occ): Store error condition for rate-limited polls

2019-04-18T01:41:05+00:00

The OCC driver limits the rate of sending poll commands to the OCC. If a user reads a hwmon entry after a poll response resulted in an error and is rate-limited, the error is invisible to the user. Fix this by storing the last error and returning that in the rate-limited case. OpenBMC-Staging-Count: 1 Signed-off-by: Eddie James Signed-off-by: Andrew Jeffery

hwmon (occ): Fix extended status bits

2019-04-16T03:47:37+00:00

The occ's extended status is checked and shown as sysfs attributes. But the code was incorrectly checking the "status" bits. Fix it by checking the "ext_status" bits. Signed-off-by: Lei YU Reviewed-by: Eddie James Signed-off-by: Andrew Jeffery

In the case of power sensor version 0xA0, the sensor indexing overlapped with the "caps" power sensors, resulting in probe failure and kernel warnings.
