2010-03-05hwmon: Remove the deprecated adt7473 driverAmerigo Wang
adt7473 driver is obsoleted by adt7475 driver. And it is scheduled to be removed in Feb 2010. Signed-off-by: WANG Cong <amwang@redhat.com> Signed-off-by: Jean Delvare <khali@linux-fr.org>
2010-03-05hwmon: Fix off-by-one kind valuesJean Delvare
Recent changes on the I2C front have left off-by-one array indexes in 3 hwmon drivers. Fix them. Faulty commit: e5e9f44c2 i2c: Drop I2C_CLIENT_INSMOD_2 to 8 Reported-by: Dan Carpenter <error27@gmail.com> Signed-off-by: Jean Delvare <khali@linux-fr.org> Cc: Hans de Goede <hdegoede@redhat.com> Cc: Andre Prendel <andre.prendel@gmx.de> Cc: stable@kernel.org
2010-03-05hwmon: (tmp421) Fix temperature conversionsJean Delvare
The low bits of temperature registers are status bits, they must be masked out before converting the register values to temperatures. Signed-off-by: Jean Delvare <khali@linux-fr.org> Tested-by: Andre Prendel <andre.prendel@gmx.de> Cc: stable@kernel.org
2010-03-05hwmon: (tmp421) Restore missing inputsJean Delvare
An off-by-one error caused some inputs to not be created by the driver when they should. TMP421 gets only one input instead of two, TMP422 gets two instead of three, etc. Fix the bug by listing explicitly the number of inputs each device has. Signed-off-by: Jean Delvare <khali@linux-fr.org> Tested-by: Andre Prendel <andre.prendel@gmx.de> Cc: stable@kernel.org

2010-03-05hwmon: (adt7411) Improve lockingWolfram Sang
Add proper locking for the cached variables. Also get rid of ref_is_vdd, which became obsolete. Signed-off-by: Wolfram Sang <w.sang@pengutronix.de> Signed-off-by: Jean Delvare <khali@linux-fr.org>
2010-03-05hwmon: Add driver for ADT7411 voltage and temperature sensorWolfram Sang
Add basic support for the ADT7411. Reads out all conversion results (via I2C, SPI yet missing) and allows some on-the-fly configuration. Tested with a custom board. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Signed-off-by: Wolfram Sang <w.sang@pengutronix.de> Signed-off-by: Jean Delvare <khali@linux-fr.org>

2010-03-05hwmon: (g760a) Make rpm_from_cnt staticJean Delvare
Function rpm_from_cnt is only used internally so it can be made static. Make it inline while we're here, for performance reasons (although hopefully gcc would figure out by itself...) Signed-off-by: Jean Delvare <khali@linux-fr.org> Cc: Herbert Valerio Riedel <hvr@gnu.org> Acked-by: Martin Michlmayr <tbm@cyrius.com>
2010-03-05hwmon: (it87) Validate auto pwm settingsJean Delvare
Before switching to automatic fan control mode, make sure that all the trip points make sense. Otherwise, the control loop could lead to weird fan behavior. Signed-off-by: Jean Delvare <khali@linux-fr.org>
2010-03-05hwmon: (it87) Add support for old automatic fan speed controlJean Delvare
Add support for the automatic fan speed control interface as implemented by IT8705F chips up to revision F and IT8712F chips up to revision G. This implementation fits very well in our standard sysfs interface. I implemented the old and not the new interface because the only chip I have at hand is an old one, and the new interface is more difficult to map to the standard sysfs interface. Adding support later should be possible though, if someone with a supported chip is interested. Signed-off-by: Jean Delvare <khali@linux-fr.org>
2010-03-05hwmon: (it87) Drop dead web links in documentationJean Delvare
Unfortunately ITE is no longer publicly providing datasheets for their IT87xxF series of chips. They may send them on request if you ask politely. Signed-off-by: Jean Delvare <khali@linux-fr.org>
2010-03-05hwmon: (it87) Add an entry in MAINTAINERSJean Delvare
As I've just done a lot of changes to the it87 driver, I volunteer to maintain it for the year to come. Signed-off-by: Jean Delvare <khali@linux-fr.org>
2010-03-05hwmon: (it87) Use strict_strtol instead of simple_strtolJean Delvare
For consistency and robustness, use strict_strtol instead of simple_strtol. Signed-off-by: Jean Delvare <khali@linux-fr.org>
2010-03-05hwmon: (it87) Fix many checkpatch errors and warningsJean Delvare
Fix 20 errors and 11 warnings reported by the checkpatch script. The remainining errors would require more work. The remaining warnings will be addressed later. Signed-off-by: Jean Delvare <khali@linux-fr.org>
2010-03-05hwmon: (it87) Add support for beep on alarmJean Delvare
The IT87xxF chips support beeping on alarm, if properly wired and configured. There is one control bit for each input type (temperature, fan, voltage.) Let the user see and change them. Signed-off-by: Jean Delvare <khali@linux-fr.org>
2010-03-05hwmon: (it87) Create vid attributes by groupJean Delvare
Only VID-related attributes are left in it87_attributes_opt, so we might as well rename it to it87_attributes_vid and use this group to create all attributes at once. Signed-off-by: Jean Delvare <khali@linux-fr.org>
2010-03-05hwmon: (it87) Refactor attributes creation and removalJean Delvare
There is a lot of code redundancy in the creation of the fan and pwm attributes. Move these attributes to arrays so that the code can be simplified. This in turns makes the attributes removal code larger, so move it to a separate function that can be called in both the standard removal case and the error path during probing. Signed-off-by: Jean Delvare <khali@linux-fr.org>
2010-03-05hwmon: (it87) Expose the PWM/temperature mappingsJean Delvare
Let the user read the PWM-to-temperature mappings. Until the trip points are also exposed, this is essentially a way to know how the BIOS has set things up. The ability to change the settings will be added later, together with the trip points. Signed-off-by: Jean Delvare <khali@linux-fr.org>
2010-03-05hwmon: (it87) Display fan outputs in automatic mode as suchJean Delvare
The it87 driver doesn't yet support automatic fan control. Let it at least tell the user when a fan output is in automatic mode. Also let the user switch from automatic mode (possibly set by the BIOS) to manual mode and back without losing the settings. Signed-off-by: Jean Delvare <khali@linux-fr.org>
2010-03-05hwmon: (lm90) Add SMBus alert supportJean Delvare
Tested successfully with an ADM1032 chip on its evaluation board. It should work fine with all other chips as well. At this point this is more of a proof-of-concept, we don't do anything terribly useful on SMBus alert: we simply log the event. But this could later evolve into libsensors signaling so that user-space applications can take an appropriate action.

2010-03-05hwmon: (lm90) Restore configuration on exitJean Delvare
Restore the chip configuration when unloading the driver. This ensures we don't leave the chip running if it was initially stopped. Signed-off-by: Jean Delvare <khali@linux-fr.org>
2010-03-05hwmon: (lm90) Add support for the Winbond/Nuvoton W83L771AWG/ASGJean Delvare

2010-03-05NFS: Replace __nfs_write_mapping with sync_inode()Trond Myklebust
Now that we have correct COMMIT semantics in writeback_single_inode, we can reduce and simplify nfs_wb_all(). Also replace nfs_wb_nocommit() with a call to filemap_write_and_wait(), which doesn't need to hold the inode->i_mutex. With that done, we can eliminate nfs_write_mapping() altogether. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
2010-03-05NFS: Simplify nfs_wb_page_cancel()Trond Myklebust

2010-03-05NFS: Ensure inode is always marked I_DIRTY_DATASYNC, if it has unstable pagesTrond Myklebust
Since nfs_scan_list() doesn't wait for locked pages, we have a race in which it is possible to end up with an inode that needs to send a COMMIT, but which does not have the I_DIRTY_DATASYNC flag set. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

2010-03-05NFS: Reduce the number of unnecessary COMMIT callsTrond Myklebust
If the caller is doing a non-blocking flush, and there are still writebacks pending on the wire, we can usually defer the COMMIT call until those writes are done. Also ensure that we honour the wbc->nonblocking flag. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
2010-03-05NFS: Add a count of the number of unstable writes carried by an inodeTrond Myklebust
In order to know when we should do opportunistic commits of the unstable writes, when the VM is doing a background flush, we add a field to count the number of unstable writes. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
2010-03-05NFS: Cleanup - move nfs_write_inode() into fs/nfs/write.cTrond Myklebust
The sole purpose of nfs_write_inode is to commit unstable writes, so move it into fs/nfs/write.c, and make nfs_commit_inode static. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
