hwmon: (lm92) Use permission specific SENSOR[_DEVICE]_ATTR variants

2019-02-18T22:23:29Z

Use SENSOR[_DEVICE]_ATTR[_2]_{RO,RW,WO} to simplify the source code, to improve readability, and to reduce the chance of inconsistencies. Also replace any remaining S_ in the driver 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

hwmon: (lm92) Add max6635 to lm92_id[]

2018-03-22T16:33:24Z

Since autodetection of this chip was removed, it makes sense to add prefix max6635 so that the device can be instantiated by its actual name. Signed-off-by: Alvaro Gamez Machado Reviewed-by: Jean Delvare Signed-off-by: Guenter Roeck

hwmon: (lm92) Do not try to detect MAX6635

2018-03-22T16:32:05Z

Maxim MAX663x family are mostly compatible with LM92, but they lack any identification register. Weakening the detect function would make it prone to false positives, and current one doesn't detect all chips. Therefore, the detect function for max6635 devices is removed in favor of explicit device instatiation. Signed-off-by: Alvaro Gamez Machado Reviewed-by: Jean Delvare Signed-off-by: Guenter Roeck

hwmon: (lm92) use permission-specific DEVICE_ATTR variants

2017-01-02T18:19:45Z

Use DEVICE_ATTR_RO for read-only attributes. This simplifies the source code, improves readbility, and reduces the chance of inconsistencies. The conversion was done automatically using coccinelle. It was validated by compiling both the old and the new source code and comparing its text, data, and bss size. Signed-off-by: Julia Lawall [groeck: Update description] Signed-off-by: Guenter Roeck

hwmon: (lm92) Prevent overflow problem when writing large limits

2014-08-06T00:48:52Z

On platforms with sizeof(int) < sizeof(long), writing a temperature limit larger than MAXINT will result in unpredictable limit values written to the chip. Avoid auto-conversion from long to int to fix the problem. The hysteresis temperature range depends on the value of data->temp[attr->index], since val is subtracted from it. Use a wider clamp, [-120000, 220000] should do to cover the possible range. Also add missing TEMP_TO_REG() on writes into cached hysteresis value. Also uses clamp_val to simplify the code a bit.
