2010-10-28hwmon: (w83795) Rework beep_enable implementationJean Delvare
Handle beep_enable just like all other beep bits. It doesn't need anything special, so let's avoid redundant code. This also saves a duplicate register read at initialization time. Signed-off-by: Jean Delvare <khali@linux-fr.org>
2010-10-28hwmon: (w83795) Report PECI agent Tbase valuesJean Delvare
On systems with PECI, report PECI agent Tbase temperature values. This is informative only. Signed-off-by: Jean Delvare <khali@linux-fr.org>
2010-10-28hwmon: (w83795) Properly handle negative temperaturesJean Delvare
The temperature registers hold regular 2's complement values, no need to add any arithmetics. Signed-off-by: Jean Delvare <khali@linux-fr.org>
2010-10-28hwmon: (w83795) Rename temperature limit attributesJean Delvare
Follow the standard for temperature limit attribute naming, so that libsensors will pick the values. Signed-off-by: Jean Delvare <khali@linux-fr.org>
2010-10-28hwmon: (w83795) Fix PWM duty cycle frequency attributesJean Delvare
The PWM duty cycle frequenty attributes are improperly named (fanN_div instead of pwmN_div) and contain raw values instead of actual frequencies. Rename them and fix their contents. Also improve the logic when the user asks for a new frequency, to always pick the closest supported frequency. The algorithm could certainly be optimized, but the operation is infrequent enough that I don't think it's worth the effort. Signed-off-by: Jean Delvare <khali@linux-fr.org>
2010-10-28hwmon: (w83795) Add support for dynamic in0-2 limitsJean Delvare
The W83795G can be configured to set the in0, in1 and/or in2 voltage limits dynamically based on VID input pins. Switch the respective sysfs attributes to read-only. Signed-off-by: Jean Delvare <khali@linux-fr.org>
2010-10-28hwmon: (w83795) Fix LSB reading of fan speedsJean Delvare
Misplaced parentheses caused the wrong register value to be read, resulting in random LSB for fan speed values and limits. Signed-off-by: Jean Delvare <khali@linux-fr.org>
2010-10-28hwmon: (w83795) Clean up probe functionJean Delvare
* The data structure is zalloc'd, so no need to set individual fields to 0 explicitly. * Refactor the handling of pins that can be used for either temperature or voltage monitoring. * Misc other clean-ups. Signed-off-by: Jean Delvare <khali@linux-fr.org>
2010-10-28hwmon: (w83795) Fix in17-in20 gain factorJean Delvare
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>
2010-10-28hwmon: (w83795) Only start monitoring if neededJean Delvare
This saves an SMBus write if monitoring was already enabled. Signed-off-by: Jean Delvare <khali@linux-fr.org>
2010-10-28hwmon: (w83795) Add const markersJean Delvare
Attribute structures can be made const. Same for the I2C address list. Signed-off-by: Jean Delvare <khali@linux-fr.org>
2010-10-28hwmon: (w83795) Only create fan[1-8]_target files when neededJean Delvare
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>
2010-10-28hwmon: (w83795) Move PWM attributes to a dedidated arrayJean Delvare
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>
2010-10-28hwmon: (w83795) Use 2D arrays for many device attributesJean Delvare
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. Signed-off-by: Jean Delvare <khali@linux-fr.org>
2010-10-28hwmon: (w83795) Merge w83795_create_files and w83795_remove_filesJean Delvare
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>
2010-10-28hwmon: (w83795) Move file creation to a separate function tooJean Delvare
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>
2010-10-28hwmon: (w83795) Move files removal to a separate functionJean Delvare
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>
2010-10-28hwmon: (w83795) Improve detection routineJean Delvare
Check for additional identification registers. Improve debugging messages on failed detection. Signed-off-by: Jean Delvare <khali@linux-fr.org>
2010-10-28hwmon: (w83795) Refactor bank selectionJean Delvare
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>
2010-10-28hwmon: (w83795) Drop duplicate enumJean Delvare
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>
2010-10-28hwmon: (w83795) Misc cleanupsJean Delvare
* Improve driver description. * Drop unused macro. * Drop unreachable code. Signed-off-by: Jean Delvare <khali@linux-fr.org>
2010-10-28hwmon: New driver for the W83795G/ADG monitoring chipsWei Song
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>
2010-10-28hwmon: (s3c-hwmon) Depend on S3C_ADCMaurus Cuelenaere

2010-10-27ext4: optimize orphan_list handling for ext4_setattrDmitry Monakhov
Surprisingly chown() on ext4 is not SMP scalable operation. Due to unconditional orphan_del(NULL, inode) in ext4_setattr() result in significant performance overhead because of global orphan mutex, especially in no-journal mode (where orphan_add() is noop). It is possible to skip explicit orphan_del if possible.
