Subject: [PATCH v3 0/3] hwmon: ltc2992: Add support
Date: Thu, 3 Dec 2020 09:11:52 +0200 [thread overview]
Message-ID: <20201203071155.68859-1-alexandru.tachici@analog.com> (raw)
From: Alexandru Tachici <alexandru.tachici@analog.com>
LTC2992 is a rail-to-rail system monitor that
measures current, voltage, and power of two supplies.
Two ADCs simultaneously measure each supply’s current.
A third ADC monitors the input voltages and four
auxiliary external voltages (GPIOs).
1. Use hwmon to create sysfs entries for current, voltage
and power of two 0V to 100V supplies. Create sysfs entries
for voltage sensed on the 4 GPIO pins.
2. Expose to userspace the 4 open-drain GPIOs provided by ltc2992.
3. DT bindings for ltc2992.
Alexandru Tachici (3):
hwmon: ltc2992: Add support
hwmon: ltc2992: Add support for GPIOs.
dt-binding: hwmon: Add documentation for ltc2992
Changelog v2 -> v3:
- removed unnecessary includes
- removed unnecessary initialization of 'reg' in ltc2992_write_in() and ltc2992_write_power().
- removed i2c_check_functionality() in ltc2992_i2c_probe
