2010-05-17drivers: Push down BKL into various driversArnd Bergmann1-4/+6
These are the last remaining device drivers using the ->ioctl file operation in the drivers directory (except from v4l drivers). [fweisbec: drop i8k pushdown as it has been done from procfs pushdown branch already] Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Frederic Weisbecker <fweisbec@gmail.com>
2010-03-30hwmon: (w83793) Saving negative errors in unsignedDan Carpenter1-1/+1
"ret" is used to store the return value for watchdog_trigger() and it should be signed for the error handling to work. Signed-off-by: Dan Carpenter <error27@gmail.com> Acked-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Jean Delvare <khali@linux-fr.org>
2010-03-06hwmon: (w83793) Add watchdog functionalitySven Anders1-3/+479
Add watchdog functionality to the Winbond W83793 driver. Signed-off-by: Sven Anders <anders@anduras.de> Acked-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Jean Delvare <khali@linux-fr.org>
2009-12-14i2c: Drop I2C_CLIENT_INSMOD_1Jean Delvare1-2/+1
This macro simply declares an enum, so drivers might as well declare it themselves. Signed-off-by: Jean Delvare <khali@linux-fr.org> Tested-by: Wolfram Sang <w.sang@pengutronix.de>
2009-12-14i2c: Get rid of struct i2c_client_address_dataJean Delvare1-1/+1
Struct i2c_client_address_data only contains one field at this point, which makes its usefulness questionable. Get rid of it and pass simple address lists around instead. Signed-off-by: Jean Delvare <khali@linux-fr.org> Tested-by: Wolfram Sang <w.sang@pengutronix.de>
2009-12-14i2c: Drop the kind parameter from detect callbacksJean Delvare1-2/+2
The "kind" parameter always has value -1, and nobody is using it any longer, so we can remove it. Signed-off-by: Jean Delvare <khali@linux-fr.org> Tested-by: Wolfram Sang <w.sang@pengutronix.de>
2009-12-09hwmon: Clean up detect functionsJean Delvare1-35/+18
As kind is now hard-coded to -1, there is room for code clean-ups. Signed-off-by: Jean Delvare <khali@linux-fr.org> Acked-by: Corentin Labbe <corentin.labbe@geomatys.fr> Cc: "Mark M. Hoffman" <mhoffman@lightlink.com> Cc: Juerg Haefliger <juergh@gmail.com> Cc: Riku Voipio <riku.voipio@iki.fi> Acked-by: "Hans J. Koch" <hjk@linutronix.de> Cc: Rudolf Marek <r.marek@assembler.cz>
2009-01-07hwmon: Don't overuse I2C_CLIENT_MODULE_PARMJean Delvare1-1/+4
I2C_CLIENT_MODULE_PARM is overkill for force_subclients. We really only use 4 out of the 48 slots, so we're better defining a custom variable instead. This change saves 92 bytes of data for each of the five drivers affected.

2008-07-16hwmon: (w83793) Convert to a new-style i2c driverJean Delvare1-137/+90
The new-style w83793 driver implements the optional detect() callback to cover the use cases of the legacy driver. Signed-off-by: Jean Delvare <khali@linux-fr.org>
2008-04-27hwmon: (w83793) VID and VRM handling cleanupsJean Delvare1-12/+14
* Rework the device initialization function so as to read the "Multi-Function Pin Control" register (0x58) once instead of twice. I2C transactions aren't cheap so this speeds up the driver loading. * Only create the "vrm" attribute if at least one VID value is available.

2008-02-19hwmon: normal_i2c arrays should be constMark M. Hoffman1-1/+2
Signed-off-by: Mark M. Hoffman <mhoffman@lightlink.com>
2008-02-08hwmon: VRM is not written to registersJean Delvare1-6/+2
What was true of reading the VRM value is also true of writing it: not being a register value, it doesn't need hardware access, so we don't need a reference to the i2c client. This allows for a minor code cleanup. As gcc appears to be smart enough to simplify the generated code by itself, this cleanup only affects the source code, the generated binaries are unchanged.

2008-02-08hwmon: (w83793) remove duplicated definesNicolas Kaiser1-4/+1

2007-01-19hwmon/w83793: Remove the description of AMDSI and update the voltage formulaGong Jun1-5/+12
