2024-11-10hwmon: (ina226) Add support for SY24655Wenliang Yan1-2/+25
SY24655: Support for current and voltage detection as well as power calculation. Signed-off-by: Wenliang Yan <wenliang202407@163.com> Message-ID: <20241106150547.2538-1-wenliang202407@163.com> [groeck: Changed order of compatible entries; dropped spurious extra return statement in is_visible(); fixed code problems] Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2024-11-10hwmon: (ina2xx) Add support for INA260Guenter Roeck1-5/+18
INA260 is similar to other chips of the series, except it has an internal shunt resistor. The calibration register is therefore not present. Also, the current register address was changed, though that does not matter for the driver since the shunt voltage register (which is now the current register) value is already used to read the current.

2024-08-30hwmon: (ina2xx) Add support for current limitsGuenter Roeck1-0/+4
While the chips supported by this driver do not directly support current limits, they do support setting shunt voltage limits. The shunt voltage divided by the shunt resistor value is the current. On top of that, calibration values are set such that in the shunt voltage register and the current register report the same values. That means we can report and configure current limits based on shunt voltage limits, and we can do so with much better accuracy than by setting shunt voltage limits.

2021-01-21hwmon: (ina2) update ti,ina2xx.yaml reference in documentationMauro Carvalho Chehab1-1/+1
Changeset 94f1ab944565 ("dt-bindings: hwmon: convert TI INA2xx bindings to dt-schema") renamed: Documentation/devicetree/bindings/hwmon/ina2xx.txt to: Documentation/devicetree/bindings/hwmon/ti,ina2xx.yaml. Update its cross-reference accordingly.

2020-07-24hwmon: (ina2xx) Replace HTTP links with HTTPS onesAlexander A. Klimov1-5/+5
Rationale: Reduces attack surface on kernel devs opening the links for MITM as HTTPS traffic is much harder to manipulate. Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain `\bxmlns\b`: For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`: If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.
