* hwmon: Request the I/O regions in platform driversJean Delvare2007-05-08
| | | | | | | | | | | | | | | | | | My understanding of the resource management in the Linux 2.6 device driver model is that the devices should declare their resources, and then when a driver attaches to a device, it should request the resources it will be using, so as to mark them busy. This is how the PCI and PNP subsystems work, you can clearly see the two levels of resources (declaration and request) in /proc/ioports for these devices. So I believe that our platform hardware monitoring drivers should follow the same logic. At the moment, we only declare the resources but we do not request them. This patch adds the I/O region request and release calls. Signed-off-by: Jean Delvare <khali@linux-fr.org> Acked-by: Juerg Haefliger <juergh@gmail.com>
* hwmon: New PC87427 hardware monitoring driverJean Delvare2006-12-12
This is a new hardware monitoring driver for the National Semiconductor PC87427 Super-I/O chip. It only supports fan speed monitoring for now, while the chip can do much more. Thanks to Amir Habibi at Candelis for setting up a test system, and to Michael Kress for testing several iterations of this driver. Signed-off-by: Jean Delvare <khali@linux-fr.org>
