All the ST Sensors use the old "<foo>-trigger" rather than the standard "<foo>-devN" new standard suffix for triggers. Now much to do about it since it is ABI, but make the testing tools recognize it too. Signed-off-by:

Commit 845c8770 ("i2c / ACPI: Assign IRQ for devices that have GpioInt automatically") automatically assigns the first ACPI GPIO interrupt in client->irq, so we can remove the probing code from drivers that use only one interrupt. Commit 0f079650 ("iio: remove gpio interrupt probing from drivers that use a single interrupt") removes gpio interrupt probing from most drivers. This patch cleans the remaining ones. Signed-off-by:

GPIO handling code has been removed from the drivers (since this is now handled by the ACPI core) in commit 0f079650 ("iio: remove gpio interrupt probing from drivers that use a single interrupt"). Remove the include for linux/gpio/consumer.h since it is no longer used. Signed-off-by:

Some i2c busses (e.g.: Synopsys DesignWare I2C adapter) need to enable/disable the bus at each i2c transfer and must wait for the enable/disable to happen before sending the data. When reading data in the trigger handler, the kxcjk-1013 accel driver does one i2c transfer for each axis. This has an impact on the frequency of the accelerometer at high sample rates due to additional delays introduced by the i2c bus at each transfer. Reading all axis values in one i2c transfer reduces the delays introduced by the i2c bus. Uses i2c_smbus_read_i2c_block_data_or_emulated that will fallback to reading each axis as a separate word in case i2c block read is not supported. Signed-off-by:

The driver goes to some length to dynamically allocate an array to hold the channel addresses. However no ST sensor has more than three channels (x, y, z at most). Instead of kmalloc():ing and kfree():in the address array, just use a fixed array of three elements. Cc: Giuseppe Barba <giuseppe.barba@st.com> Signed-off-by:

flush_scheduled_work is scheduled for deprecation. Replace cancel_delayed_work and flush_scheduled_work with cancel_delayed_work_sync instead to ensure there is no pending or running work item. Since there is only one work item, chip->poweroff_work, there are no further dependencies of flush_scheduled_work(). Acked-by:

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. Signed-off-by:

Replace the code that guarantees the device stays in direct mode with iio_device_{claim|release}_direct_mode() which does same. Signed-off-by: -
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: -

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.

Martin Kepplinger authored
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. Signed-off-by:
