* hwmon/lm78: Be less i2c_client-centricJean Delvare2007-05-08
| | | | | | | | Use the driver data structure as the main device reference, instead of the i2c client. It makes the driver a bit smaller, and makes more sense as this is an hybrid driver, supporting both I2C and ISA devices. Signed-off-by: Jean Delvare <khali@linux-fr.org>

* hwmon-vid: Add support for VIA EstherRudolf Marek2007-05-08

* hwmon: Only call vid_which_vrm() when neededJean Delvare2007-05-08
| | | | | | | | | | | Some hardware monitoring drivers create the VID/VRM interface files conditionally depending on the chip model or configuration. We should only call vid_which_vrm() when we are actually going to create the files. Not only it is more logical and efficient that way, but it also prevents printing unnecessary warnings such as the one reported here: http://lists.lm-sensors.org/pipermail/lm-sensors/2007-February/018954.html Signed-off-by: Jean Delvare <khali@linux-fr.org>
* hwmon/smsc47m1: Get rid of a useless mutexJean Delvare2007-05-08
| | | | | | | | | The smsc47m1 driver uses a mutex to protect the accesses to the hardware registers. It really doesn't need any protection, as the register space is flat. Get rid of that mutex for a smaller and faster driver. Signed-off-by: Jean Delvare <khali@linux-fr.org>
* hwmon/smsc47m1: Add support for the LPC47M292Jean Delvare2007-05-08
| | | | | | | | The new SMSC LPC47M292 Super-I/O chip is a bit different from the previous ones, it supports a 3rd fan, but unfortunately the pin configuration registers are different. Signed-off-by: Jean Delvare <khali@linux-fr.org>
* 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/w83627ehf: Fix the fan5 clock divider writeJean Delvare2007-04-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Users have been complaining about the w83627ehf driver flooding their logs with debug messages like: w83627ehf 9191-0a10: Increasing fan 4 clock divider from 64 to 128 or: w83627ehf 9191-0290: Increasing fan 4 clock divider from 4 to 8 The reason is that we failed to actually write the LSB of the encoded clock divider value for that fan, causing the next read to report the same old value again and again. Additionally, the fan number was improperly reported, making the bug harder to find.

* hwmon/f71805f: Fix a race conditionJean Delvare2007-02-14
| | | | | | | | | | | | I think I introduced a potential race condition bug with commit 51c997d80e1f625aea3426a8a9087f5830ac6db3. I didn't realize it back then, but platform_device_put and platform_device_release both appear to free the platform data associated with the device. This makes an explicit kfree redundant at best, and maybe even racy, as it might occur while someone still holds a reference to the platform device. Signed-off-by: Jean Delvare <khali@linux-fr.org>

* hwmon: Use subsys_initcallDavid Brownell2007-02-14
| | | | | | | | | | | | | Subsystem infrastructure should normally register with "subsys_initcall", so that it's available to drivers that may need to initialize early. This patch updates "hwmon" to do so. It's common for embedded systems to have multifunction chips with hardware monitoring interfaces, and to have those chips be used during system bringup ... before a normal "module_init" would kick, or maybe just linked so they'd init before hwmon.

* hwmon: Simplify the locking model of two driversJean Delvare2007-02-14
| | | | | | | | | | | | | | | | Many hardware monitoring drivers use two different mutexes, one to protect their per-device data structure, and one to protect the access to the device registers. These mutexes are essentially redundant, as the drivers are transfering values between the device registers and the data cache, so they almost always end up holding both mutexes at the same time. Using a single mutex will make the code more simple and faster. I am changing only two of the affected drivers here, the authors of the other affected drivers are welcome to submit similar patches if they want. Signed-off-by: Jean Delvare <khali@linux-fr.org>
