What is this autosleep? ----------------------- It slows down the device after x seconds of inactivity. The thing is, we have really achieved almost the same by runtime pm. differnces are: autosleep * uses more power during inactivity * the first read after inactivity slightly faster * complicated to understand for the user * no documented sysfs interface (afaik) * complicated to read and maintain runtime pm * already merged in mma8452 * uses less power during inactivity * first read after inactivity slower * easy to use. well documented. * easy to maintain and understand The two approaches solve the same problem. runtime pm has more advantages than autosleep and comes quite close to it's behaviour anyways. As I see it, autosleep, even if somehow supported, would never be used anyways. So resolve this issue by "ignoring" autosleep.

Alison Schofield authored
It is often the case that the driver wants to be sure a device stays in direct mode while it is executing a task or series of tasks. To accomplish this today, the driver performs this sequence: 1) take the device state lock, 2) verify it is not in a buffered mode, 3) execute some tasks, and 4) release that lock. This patch introduces a pair of helper functions that simplify these steps and make it more semantically expressive. iio_device_claim_direct_mode() If the device is not in any buffered mode it is guaranteed to stay that way until iio_release_direct_mode() is called. iio_device_release_direct_mode() Release the claim. Device is no longer guaranteed to stay in direct mode. Signed-off-by: Alison Schofield <amsfield22@gmail.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>

This adds support for Freescale's (now NXP's) FXLS8471Q accelerometer. We use MMA8451Q's configuration because for what the driver supports, FXLS8471Q is the same. Support for FXLS8471Q's features (fast SPI interface and a larger FIFO, among others) can be added to this driver anytime.

The ADIS16220 part has been obsoleted, which makes it hard to get the hardware to even test the driver. Considering this there is no expectation that the driver will be cleaned up and be able to move out of staging, so remove the driver.

This adds support for runtime power management and, if configured, activates automatic standby after 2 seconds of inactivity. Inactivity means no read of acceleration values and no events triggered or activated. If CONFIG_PM is not set, this doesn't change anything for existing users.

The devices' config registers can only be changed in standby mode. Up until now the driver just held the device *always* active, so for changing a config it was *always* necessary to switch to standby. For upcoming support for runtime pm, the device can as well be in standby mode. Instead of putting runtime pm functions in there, just keep the device in standby if it already is. This section is protected by a lock after all.

Add support for setting and retrieving OverSampling Rate independently for each of the temperature and pressure channels. This allows userspace to fine tune hardware sampling process according to the following tradeoffs : * the higher the OSR, the finer the resolution ; * the higher the OSR, the lower the noise ; BUT: * the higher the OSR, the larger the drift ; * the higher the OSR, the longer the response time, i.e. less samples per unit of time.
