* hwmon: (lm75) Drop legacy i2c driverJean Delvare2008-08-10
| | | | | | | | Drop the legacy lm75 driver, and add a detect callback to the new-style driver to achieve the same functionality. Signed-off-by: Jean Delvare <khali@linux-fr.org> Cc: David Brownell <david-b@pacbell.net>
* hwmon: (it87) Support for 16-bit fan reading in it8705 >= rev 0x03Andrew Paprocki2008-08-06
| | | | | | | | | The it8705 chip supports 16-bit fan tachometers in revisions at least >= 0x03 (Version G). This patch enables 16-bit fan readings on all revisions >= 0x03 just like the it8712, it8716, and it8718 chips.

* hwmon: (it87) Support for 16-bit fan reading in it8712 >= rev 0x07Andrew Paprocki2008-08-06
| | | | | | | | | | The it8712 chip supports 16-bit fan tachometers in revisions >= 0x07. Revisions >= 0x08 dropped support for 8-bit fan divisor registers. The patch enables 16-bit fan readings on all revisions >= 0x07 just like the it8716 and it8718 chips.

* hwmon: (hwmon-vid) Add 6-bit vid codes for AMD NPT 0Fh cpusFrank Myhr2008-08-06
| | | | | | | | | | | | | | | AMD NPT 0Fh cpus use 6 bit VID codes. Successive codes with msb 0 describe 25mV decrements, while those with msb 1 describe 12.5mV decrements. Existing hwmon-vid.c is correct only for codes with msb 0; add support for the codes with msb 1.

* hwmon: (w83627hf) Drop reset module parameterJean Delvare2008-08-06
| | | | | | | | | | | | | | | Drop the reset parameter of the w83627hf driver. It seems it wasn't that useful. It was dropped from the Linux 2.4 version of this driver back in July 2004. The only users who have reported that they were still using this parameter, needed it to switch the chip from automatic fan speed control back to manual mode. Now that the driver creates pwmN_enable sysfs files, users will be able to use these files instead, which is way less agressive.

| * hwmon: (lm85) Simplify device initialization functionJean Delvare2008-07-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Clean up and simplify the device initialization function: * Degrade error messages to warnings - what they really are. * Stop warning about VxI mode, we don't really care. * Drop comment about lack of limit initialization - that's the standard way, all hardware monitoring drivers do that. * Only read the configuration register once. * Only write back to the configuration register if needed. * Don't attempt to clear the lock bit, it locks itself to 1. * Move the function to before it's called, so that we no longer need to forware declare it.

| * hwmon: (lm85) Don't write back cached valuesJean Delvare2008-07-31
| | | | | | | | | | | | | | | | | | | | | | In set_pwm_auto_pwm_minctl, we write cached register bits back to the chip. This is a bad idea as we have no guarantee that the cache is up-to-date. Better read a fresh register value from the chip, it's safer and in fact it is also more simple.

| * hwmon: (lm75) add new-style driver bindingDavid Brownell2008-07-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | More LM75 updates: - Teach the LM75 driver to use new-style driver binding: * Create a second driver struct, using new-style driver binding methods cribbed from the legacy code. * Add a MODULE_DEVICE_TABLE (for "newER-style binding") * The legacy probe logic delegates its work to this new code. * The legacy driver now uses the name "lm75_legacy". - More careful initialization. Chips are put into 9-bit mode so the current interconversion routines will never fail. - Save the original chip configuration, and restore it on exit. (Among other things, this normally turns off the mode where the chip is constantly sampling ... and thus saves power.) So the new-style code should catch all chips that boards declare, while the legacy code catches others. This particular coexistence strategy may need some work yet ... legacy modes might best be set up explicitly by some tool not unlike "sensors-detect". (Or else completely eradicated...)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Minor cleanup and reorg of the lm75 code. - Kconfig provides a larger list of lm75-compatible chips - A top comment now says what the driver does (!) ... as in, just what sort of sensor is this?? - Section comments now delineate the various sections of the driver: hwmon attributes, driver binding, register access, module glue. One driver binding function moved out of the attribute section, as did the driver struct itself. - Minor tweaks to legacy probe logic: correct a comment, and remove a pointless variable. - Whitespace, linelength, and comment fixes. This patch should include no functional changes. It's preparation for adding new-style (driver model) I2C driver binding.
