Support MAX34451, fix sensor type, enum issues Add support for MAX34451 power sequencers, as well as fix some issues with substring matching with regards to hwmon file prefix (sensor type) and hwmon file suffix (sensor enumeration). e.g vout11 , vout would be the sensor type and 11 would be the enumeration. Test: Reboot BMC on a system with a MAX34451 present which published the following sysfs hwmon labels, e.g grep -H "" /sys/class/hwmon/hwmonXX/*_label in10_label:vout12 in11_label:vout13 in12_label:vout16 in1_label:vout1 in2_label:vout2 in3_label:vout4 in4_label:vout5 in5_label:vout6 in6_label:vout7 in7_label:vout9 in8_label:vout10 in9_label:vout11 then did dbusctl --no-pager tree xyz.openbmc_project.PSUSensor and saw the correct corresponding output voltage paths. Before the patch having an enumeration > 9 would cause issues. Change-Id: I9a82eea11f54266003c673013d0fed131f2f11fc Signed-off-by: Jason Ling <jasonling@google.com>
dbus-sensors is a collection of sensor applications that provide the xyz.openbmc_project.Sensor collection of interfaces. They read sensor values from hwmon, d-bus, or direct driver access to provide readings. Some advance non-sensor features such as fan presence, pwm control, and automatic cpu detection (x86) are also supported.
runtime re-configurable from d-bus (entity-manager or the like)
isolated: each sensor type is isolated into its own daemon, so a bug in one sensor is unlikely to affect another, and single sensor modifications are possible
async single-threaded: uses sdbusplus/asio bindings
multiple data inputs: hwmon, d-bus, direct driver access
