      hwmon: (lm75) Add support for the Dallas/Maxim DS7505 · 3fbc81e3
      Jean Delvare 提交于
      Basically it's the same as the original DS75 but much faster.

      hwmon: (lm75) Tune resolution and sample time per chip · 0cd2c72d
      Jean Delvare 提交于
      Most LM75-compatible chips can either sample much faster or with a
      much better resolution than the original LM75 chip. So far the lm75
      driver did not let the user take benefit of these improvements. Do it
      now.
      
      I decided to almost always configure the chip to use the best
      resolution possible, which also means the longest sample time. The
      only chips for which I didn't are the DS75, DS1775 and STDS75, because
      they are really too slow in 12-bit mode (1.2 to 1.5 second worst case)
      so I went for 11-bit mode as a more reasonable tradeoff. This choice is
      dictated by the fact that the hwmon subsystem is meant for system
      monitoring, it has never been supposed to be ultra-fast, and as a
      matter of fact we do cache the sampled values in almost all drivers.
      
      If anyone isn't pleased with these default settings, they can always
      introduce a platform data structure or DT support for the lm75. That
      being said, it seems nobody ever complained that the driver wouldn't
      refresh the value faster than every 1.5 second, and the change made
      it faster for all chips even in 12-bit mode, so I don't expect any
      complaint.

      hwmon: (lm75) Prepare to support per-chip resolution and sample time · 87d0621a
      Jean Delvare 提交于
      Prepare the lm75 driver to support per-chip resolution and sample
      time. For now we only make the code generic enough to support it, but
      we still use the same, unchanged resolution (9-bit) and sample time
      (1.5 s) for all chips.
