Update datasheet references. Replace misleading 'force parameter needed' with 'must be instantiated explicitly'. Explain the reason for the missing auto-detection. Mention all supported chips in Kconfig. Reviewed-by: Tzung-Bi Shih <tzungbi@kernel.org> Signed-off-by: Guenter Roeck <linux@roeck-us.net>

Description
|
|
-----------
|
|
|
|
This driver implements support for the National Semiconductor / Texas
|
|
Instruments LM92 temperature sensor.
|
|
|
|
Each LM92 temperature sensor supports a single temperature sensor. There are
|
|
alarms for high, low, and critical thresholds. There's also an hysteresis to
|
|
control the thresholds for resetting alarms.
|
|
|
|
The driver also supports LM76 and Maxim MAX6633/MAX6634/MAX6635, which are
|
|
mostly compatible but do not have a vendor ID register and therefore must be
|
|
instantiated explicitly.
