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 Christopher Bostic (2): hwmon: (ucd9000) Add gpio chip interface hwmon: (ucd9000) Add debugfs attributes to provide mfr_status drivers/hwmon/pmbus/ucd9000.c | 338 +++++++++++++++++++++++++++++++++++++++++- 1 file changed, 337 insertions(+), 1 deletion(-) -- 1.8.3.1
