Subject: [PATCH V3 0/4] hwmon: ina3221: Add selective summation support
Date: Thu, 21 Sep 2023 14:08:14 +0100	[thread overview]
Message-ID: <20230921130818.21247-1-jonathanh@nvidia.com> (raw)

The current INA3221 driver always sums the shunt voltage for all enabled
channels regardless of the shunt-resistor used for each channel. Summing
the shunt-voltage for channels is only meaningful if the shunt resistor
is the same for each channel. This series adds device-tree support to
allow which channels are summed in device-tree.

Changes since V2:
- Added note to binding-doc to indicate that input channels must be
  explicitly disabled.
- Corrected ordering of properties in the binding-doc
- Updated license for the binding-doc to be dual licensed.
- Changed newly added property from 'summation-bypass' to
  summation-disable'.
- Documented type for the new 'summation-disable' property.
- Corrected spelling and comments as per the feedback received.
- Used debugfs instead of sysfs for exposing the 'summation-disable'
  status for each input channel.
- Populated missing instances for the ina3221 device for Tegra234
  boards.
- Populated ina219 device for the NVIDIA IGX board (not strictly
  related to this series but related to populating all
  power-sensors for Tegra234 boards)

Changes since V1:
- Added yaml conversion patch for binding-doc
- Added binding-doc documentation patch for new property
- Added patch to populate ina3221 devices for Tegra234.
