Guenter Roeck 196df56c3d hwmon: (lm90) Add basic support for TI TMP461 ... [ Upstream commit f8344f7693 ] TMP461 is almost identical to TMP451 and was actually detected as TMP451 with the existing lm90 driver if its I2C address is 0x4c. Add support for it to the lm90 driver. At the same time, improve the chip detection function to at least try to distinguish between TMP451 and TMP461. As a side effect, this fixes commit 24333ac26d ("hwmon: (tmp401) use smb word operations instead of 2 smb byte operations"). TMP461 does not support word operations on temperature registers, which causes bad temperature readings with the tmp401 driver. The lm90 driver does not perform word operations on temperature registers and thus does not have this problem. Support is listed as basic because TMP461 supports a sensor resolution of 0.0625 degrees C, while the lm90 driver assumes a resolution of 0.125 degrees C. Also, the TMP461 supports negative temperatures with its default temperature range, which is not the case for similar chips supported by the lm90 and the tmp401 drivers. Those limitations will be addressed with follow-up patches. Fixes: 24333ac26d ("hwmon: (tmp401) use smb word operations instead of 2 smb byte operations") Reported-by: David T.
