[RFC linux dev-4.10 0/3] drivers/hwmon/pmbus: core extensions

[Eddie James <eajames@linux.vnet.ibm.com>]

From: "Edward A. James" <eajames@us.ibm.com>

This series adds some functionality to the pmbus core.

The first two patches are fixes to enable the use of the STATUS_WORD register
which was completely unused in existing pmbus. This allows the use of more
default alarm/fault attributes for default pmbus sensors.

The third patch adds "status" attributes to each class of hwmon sensor created
by pmbus. For example, in1_status and temp1_status. These will display the
associated raw status register (STATUS_INPUT and STATUS_TEMPERATURE). These
will probably be essential for the UCD driver, and certainly very convenient
for the power supply driver.

An alternative I considered was breaking all the status registers out into
bits, but some bits seem to be device-dependent and therefore couldn't be named
correctly or at all in the pmbus core. This would also really make the hwmon
directory messy, unless you have a separate directory for that, either in the
device directory or under the hwmon directory (not sure if that's even
possible).

Edward A. James (3):
  drivers/hwmon/pmbus: Use STATUS_WORD by default and do correct access
  drivers/hmwon/pmbus: store STATUS_WORD in status registers
  drivers/hwmon/pmbus: Add sensor status to pmbus attributes
