* hwmon: (w83795) Fix in17-in20 gain factorJean Delvare2010-10-28
| | | | | | | Gain bit set means 1x gain and cleared means 8x gain, not the other way around. Signed-off-by: Jean Delvare <khali@linux-fr.org>
* hwmon: (w83795) Only start monitoring if neededJean Delvare2010-10-28
| | | | | | This saves an SMBus write if monitoring was already enabled. Signed-off-by: Jean Delvare <khali@linux-fr.org>
* hwmon: (w83795) Add const markersJean Delvare2010-10-28
| | | | | | | Attribute structures can be made const. Same for the I2C address list. Signed-off-by: Jean Delvare <khali@linux-fr.org>
* hwmon: (w83795) Only create fan[1-8]_target files when neededJean Delvare2010-10-28
| | | | | | | | Only create fan[1-8]_target files when the fan in question can be controlled (PWM output is present.) Also name these files according to the standard. Signed-off-by: Jean Delvare <khali@linux-fr.org>
* hwmon: (w83795) Move PWM attributes to a dedidated arrayJean Delvare2010-10-28
| | | | | | | Use a dedicated 2D array for PWM attributes. This way, PWM attributes are handled the same way as other attributes, this is more consistent. Signed-off-by: Jean Delvare <khali@linux-fr.org>
* hwmon: (w83795) Use 2D arrays for many device attributesJean Delvare2010-10-28
| | | | | | | | | | | Use 2D arrays for in, fan, temp and dts device attributes. Using linear arrays is too risky as we have to skip some groups depending on the device model and configuration. Adding or removing an attribute would let the driver build silently but then it would crash at runtime. With 2D arrays, the consistency checking happens at build time, which is much safer.

* hwmon: (w83795) Merge w83795_create_files and w83795_remove_filesJean Delvare2010-10-28
| | | | | | | | | | Functions w83795_create_files and w83795_remove_files iterate over the same set of files, just calling a different function. Merge them into a single function which takes the action as a parameter. This saves code, and also ensure that file creation and deletion are in sync. Signed-off-by: Jean Delvare <khali@linux-fr.org>
* hwmon: (w83795) Move file creation to a separate function tooJean Delvare2010-10-28
| | | | | | | Function w83795_probe() is way too big, move file creation to a separate function to make it more readable. Signed-off-by: Jean Delvare <khali@linux-fr.org>
* hwmon: (w83795) Move files removal to a separate functionJean Delvare2010-10-28
| | | | | | | | Sysfs files must be removed on device removal but also when device registration fails. Move the code to a separate function to avoid code redundancy. Signed-off-by: Jean Delvare <khali@linux-fr.org>
* hwmon: (w83795) Improve detection routineJean Delvare2010-10-28
| | | | | | | Check for additional identification registers. Improve debugging messages on failed detection. Signed-off-by: Jean Delvare <khali@linux-fr.org>
* hwmon: (w83795) Refactor bank selectionJean Delvare2010-10-28
| | | | | | | | Move the bank selection code to a separate function, to avoid duplicating it in read and write functions. Improve error reporting on register access error. Signed-off-by: Jean Delvare <khali@linux-fr.org>
* hwmon: (w83795) Drop duplicate enumJean Delvare2010-10-28
| | | | | | | | Enum chips and chip_types are redundant, get rid of the former. Fix the detection code to properly identify the chip variant and name the client accordingly. Signed-off-by: Jean Delvare <khali@linux-fr.org>
* hwmon: (w83795) Misc cleanupsJean Delvare2010-10-28

* hwmon: New driver for the W83795G/ADG monitoring chipsWei Song2010-10-28
| | | | | | | | | | | | | | | | | | There is still much work needed, but I wanted to give Wei the credit he deserves. I've merged some of my own fixes already, to make gcc and checkpatch happy. Individual fixes and improvements from me will follow. [JD: Fix build errors] [JD: Coding style cleanups] [JD: Get rid of forward declarations] [JD: Drop VID support] [JD: Drop fault output control feature] [JD: Use lowercase for inline function names] [JD: Use strict variants of the strtol/ul functions] [JD: Shorten the read and write function names] Signed-off-by: Jean Delvare <khali@linux-fr.org>

* hwmon: lis3: use block read to access data registersSamu Onkalo2010-10-25
| | | | | | | | | | | | | | Add optional blockread function to interface driver. If available the chip driver uses it for data register access. For 12 bit device it reads 6 bytes to get 3*16bit data. For 8 bit device it reads out 5 bytes since every second byte is dummy. This optimizes bus usage and reduces number of operations and interrupts needed for one data update.

Added possibility to configure interrupts to trig on both rising and falling edge.

* hwmon: lis3: Cleanup interrupt handlingSamu Onkalo2010-10-25
| | | | | | | | | | | | | | | | Irqcfg moved to chip data instead of platform data. This simplifies access in interrupt handler little bit. Input device open and close functions set status for interrupt threaded handler once. Unnecessary check for interrupt source removed since it is enough that active interrupt line indicates that there was an interrupt.

* hwmon: (lis3) add axes module parameter for custom axis-mappingTakashi Iwai2010-10-25
| | | | | | | | | | | | | | | | | | The axis-mapping of lis3dev device on many (rather most) HP machines doesn't follow the standard. When each new model appears, users need to adjust again. Testing this requires the rebuild of kernel, thus it's not trivial for end-users. This patch adds a module parameter "axes" to allow a custom axis-mapping without patching and recompiling the kernel driver. User can pass the parameter such as axes=3,2,1. Also it can be changed via sysfs.
