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 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 | 340 +++++++++++++++++++++++++++++++++++++++++- 1 file changed, 339 insertions(+), 1 deletion(-) -- 1.8.3.1
