* hwmon: (w83793) Convert to a new-style i2c driverJean Delvare2008-07-161-137/+90
| | | | | | | The new-style w83793 driver implements the optional detect() callback to cover the use cases of the legacy driver. Signed-off-by: Jean Delvare <khali@linux-fr.org>
* hwmon: (w83793) VID and VRM handling cleanupsJean Delvare2008-04-271-12/+14
| | | | | | | | | | | | | | * Rework the device initialization function so as to read the "Multi-Function Pin Control" register (0x58) once instead of twice. I2C transactions aren't cheap so this speeds up the driver loading. * Only create the "vrm" attribute if at least one VID value is available.

* hwmon: VRM is not written to registersJean Delvare2008-02-071-6/+2
| | | | | | | | | | | | What was true of reading the VRM value is also true of writing it: not being a register value, it doesn't need hardware access, so we don't need a reference to the i2c client. This allows for a minor code cleanup. As gcc appears to be smart enough to simplify the generated code by itself, this cleanup only affects the source code, the generated binaries are unchanged.
