* hwmon: lis3: restore axis enabled bitsSamu Onkalo2010-10-251-1/+1
| | | | | | | | | All axis enable bits are set to 0 at module remove. Restore reset default value at init. Signed-off-by: Samu Onkalo <samu.p.onkalo@nokia.com> Acked-by: Eric Piel <eric.piel@tremplin-utc.net> Signed-off-by: Guenter Roeck <guenter.roeck@ericsson.com>
* hwmon: (lis3) add axes module parameter for custom axis-mappingTakashi Iwai2010-10-251-1/+2
| | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | If CONFIG_PM was selected and lis3lv02d_platform_data was NULL, the kernel will be panic when halt command run.

* spi: prefix modalias with "spi:"Anton Vorontsov2009-09-231-1/+1
| | | | | | | | | | | | | | | | | | | | | This makes it consistent with other buses (platform, i2c, vio, ...). I'm not sure why we use the prefixes, but there must be a reason. This was easy enough to do it, and I did it.

* lis3: add power management functionsDaniel Mack2009-09-221-0/+28
| | | | | | | | | | | | | | | This enabled power management functions for the SPI transport layer of the lis3 devices. The device's suspend mode is only entered in case no wakeup threshold has been given. In this case, the device is supposed to wake up the system and must thus not be put to deep sleep.

* lis3: add click functionDaniel Mack2009-06-161-0/+1
| | | | | | | | | | | | | | | | | | | | The LIS302DL accelerometer chip has a 'click' feature which can be used to detect sudden motion on any of the three axis. Configuration data is passed via spi platform_data and no action is taken if that's not specified, so it won't harm any existing platform. To make the configuration effective, the IRQ lines need to be set up appropriately. This patch also adds a way to do that from board support code. The DD_* definitions were factored out to an own enum because they are specific to LIS3LV02D devices.

* lis3: SPI transport layerDaniel Mack2009-04-011-0/+114
Make use of the new abstraction layer and add a new transport layer for spi. Works fine on a PXA based board.
