hwmon: (tmp421) fix rounding for negative values

2021-10-06T13:31:23+00:00

[ Upstream commit 724e8af85854c4d3401313b6dd7d79cf792d8990 ] Old code produces -24999 for 0b1110011100000000 input in standard format due to always rounding up rather than "away from zero". Use the common macro for division, unify and simplify the conversion code along the way.

hwmon: (tmp421) report /PVLD condition as fault

2021-10-06T13:31:23+00:00

[ Upstream commit 540effa7f283d25bcc13c0940d808002fee340b8 ] For both local and remote sensors all the supported ICs can report an "undervoltage lockout" condition which means the conversion wasn't properly performed due to insufficient power supply voltage and so the measurement results can't be trusted.

hwmon: (tmp421) Replace S_ with octal values

2021-10-06T13:31:22+00:00

[ Upstream commit b626eb22f9e17fcca4e262a8274e93690068557f ] Replace S_ with octal values. The conversion was done automatically with coccinelle. The semantic patches and the scripts used to generate this commit log are available at https://github.com/groeck/coccinelle-patches/hwmon/. This patch does not introduce functional changes. It was verified by compiling the old and new files and comparing text and data sizes. Signed-off-by: Guenter Roeck Signed-off-by: Sasha Levin

hwmon: (tmp421) Add OF device ID table

2017-04-02T14:01:53+00:00

The driver doesn't have a struct of_device_id table but supported devices are registered via Device Trees. This is working on the assumption that a I2C device registered via OF will always match a legacy I2C device ID and that the MODALIAS reported will always be of the form i2c:. But this could change in the future so the correct approach is to have an OF device ID table if the devices are registered via OF.

Not all supported chips support the entire I2C address range. Only accept specific chips at the addresses supported by that chip. Check for invalid values in conversion rate and status registers. Signed-off-by: Guenter Roeck Reviewed-by: Jean Delvare
