Subject: [PATCH v5 0/2] hwmon: (ucd9000) Add gpio and debugfs interfaces
Date:   Thu, 15 Mar 2018 17:21:54 -0500
Message-Id: <1521152516-10829-1-git-send-email-eajames@linux.vnet.ibm.com>

Precedence: bulk

The ucd9000 series chips have gpio pins. Add a gpio chip interface to the ucd
device so that users can query and set the state of the gpio pins.

Add a debugfs interface using the existing pmbus debugfs directory to provide
MFR_STATUS and the status of the gpi faults to users.

Changes since v4:
 - max-sized buffers for smbus transfers
 - used bin2hex instead of my own code

Changes since v3:
 - remove setting of gpio_chip->owner
 - format the mfr_status data
 - switch to #ifdef rather than #if IS_ENABLED for debugfs

Changes since v2:
 - split the gpio registration into it's own function

Changes since v1:
 - dropped dev_err messages
 - made gpio chip registration conditional on having gpio pins
 - made mfr_status debugfs attribute more simple
