2014-01-21compal-laptop: Use devm_hwmon_device_register_with_groupsGuenter Roeck1-29/+23
Simplify the code and create hwmon attributes as well as hwmon device in one go. With the new hwmon API, hwmon attributes are now attached to the hwmon device. Therefore, split hwmon and device attributes into two separate groups. Platform attributes are still attached to the platform device. Also use devm_kzalloc to allocate local data structures for further simplification. Signed-off-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Matthew Garrett <matthew.garrett@nebula.com>
2014-01-21compal-laptop: Replace SENSOR_DEVICE_ATTR with DEVICE_ATTRGuenter Roeck1-33/+33
The extra argument to SENSOR_DEVICE_ATTR is not used. It is therefore not necessary to use SENSOR_DEVICE_ATTR in the first place. Replace it with DEVICE_ATTR. Signed-off-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Matthew Garrett <matthew.garrett@nebula.com>

2013-09-05platform: x86: remove unnecessary platform_set_drvdata()Jingoo Han1-1/+0
The driver core clears the driver data to NULL after device_release or on probe failure. Thus, it is not needed to manually clear the device driver data to NULL. Signed-off-by: Jingoo Han <jg1.han@samsung.com> Signed-off-by: Matthew Garrett <matthew.garrett@nebula.com>
2013-09-05platform: replace strict_strto*() with kstrto*()Jingoo Han1-2/+4
The usage of strict_strtoul() and strict_strtol() is not preferred, because strict_strtoul() and strict_strtol() are obsolete. Thus, kstrtoul() and kstrtol() should be used. Signed-off-by: Jingoo Han <jg1.han@samsung.com> Signed-off-by: Matthew Garrett <matthew.garrett@nebula.com>
2013-01-03Drivers: platform: x86: remove __dev* attributes.Greg Kroah-Hartman1-5/+5
CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

2012-01-13module_param: make bool parameters really bool (drivers & misc)Rusty Russell1-1/+1
module_param(bool) used to counter-intuitively take an int. In fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy trick. It's time to remove the int/unsigned int option. For this version it'll simply give a warning, but it'll break next kernel version. Acked-by: Mauro Carvalho Chehab <mchehab@redhat.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

2010-08-03compal-laptop: add JHL90, battery & hwmon interfaceRoald Frederickx1-105/+822
The driver now supports the Compal JHL90 (which I use) and it has some added features. The biggest novelties are a battery interface (power_supply) and a temperature and fan control interface (hmwon). It also adds a power-off feature to the backlight subsystem and it exports a few files that can enable/disable wake_on_XXX events. Much of the original code of the old features is still there, but I've changed some names to keep the naming more coherent with the added functionalities. (Sorry for the huge patch) Some technical stuff about the new driver: First of all, I'm not sure if the extra features also work on the other Compal boards. Currently they only get enabled if the DMI data indicates you are on a JHL90 board. Secondly, I've noticed a quirk in my fan controller. I have to re-send the wanted pwm-level to the controller every so often. If I don't do this, the fanspeed will slowly rise until after a couple of minutes it's at full speed. (Note that every normal userland application will probably update the pwm-level every so often anyway, based on temperature readings, so this might not be an issue in practice) If this turns out to be a problem with all the controllers, maybe we should implement a kernel timer and have the driver re-send the pwm level every XX seconds to make this transparent to userspace? (However, I couldn't immediately find a way to do this cleanly.) Additional information can be found in the source comments.

2008-12-19create drivers/platform/x86/ from drivers/misc/Len Brown1-0/+406
Move x86 platform specific drivers from drivers/misc/ to a new home under drivers/platform/x86/. The community has been maintaining x86 vendor-specific platform specific drivers under /drivers/misc/ for a few years. The oldest ones started life under drivers/acpi. They moved out of drivers/acpi/ because they don't actually implement the ACPI specification, but either simply use ACPI, or implement vendor-specific ACPI extensions. In the future we anticipate... drivers/misc/ will go away. other architectures will create drivers/platform/<arch> Signed-off-by: Len Brown <len.brown@intel.com>
