iio: accel: mma8452: Add missing documentation for name element of chip_info

2022-04-28T18:22:55Z

Documentation needed to avoid build warning with W=1 builds. It doesn't really add any non obvious information but good to have it anyway. No fixes tag as not worth backporting onto the fix that added the name element to the structure.

iio: accel: dmard06: Drop dependency on OF

2022-04-28T18:22:55Z

Nothing in this driver depends on OF firmware so drop the dependency to remove the false impression such a dependency exists. Signed-off-by: Andy Shevchenko Link: https://lore.kernel.org/r/20220413190327.30054-1-andriy.shevchenko@linux.intel.com Signed-off-by: Jonathan Cameron

iio: accel: adxl355: use fwnode_irq_get_byname()

2022-04-28T18:22:54Z

Use the generic fwnode_irq_get_byname() in place of of_irq_get_byname() to get the IRQ number from the interrupt pin. Signed-off-by: Puranjay Mohan Link: https://lore.kernel.org/r/20211109200840.135019-3-puranjay12@gmail.com Signed-off-by: Jonathan Cameron

iio: core: Simplify the registration of kfifo buffers

2022-04-10T15:25:46Z

Among all the users of the kfifo buffers, no one uses the INDIO_BUFFER_HARDWARE mode. So let's take this as a general rule and simplify a little bit the internals - overall the documentation - by eliminating unused specific cases. Use the INDIO_BUFFER_SOFTWARE mode by default with kfifo buffers, which will basically mimic what all the "non direct" modes do.

iio: core: Hide read accesses to iio_dev->currentmode

2022-04-10T15:21:45Z

In order to later move this variable within the opaque structure, let's create a helper for accessing it in read-only mode. This helper will be exposed to device drivers and kept accessible for the few that could need it. The write access to this variable however should be fully reserved to the core so in a second step we will hide this variable into the opaque structure.

iio: st_sensors: Stop abusing mlock to ensure internal coherency

2022-04-10T15:21:45Z

An odr_lock has been introduced to protect local accesses to the odr internal cache and ensure the cached value always reflected the actual value. Using the mlock() for this purpose is no longer needed, so let's drop these extra mutex_lock/unlock() calls.

iio: st_sensors: Return as early as possible from the _write_raw() callbacks

2022-04-10T15:15:02Z

As there is no cleanup to do, let's return as early as possible in the various ST sensor drivers _write_raw() callback functions. There is no functional change.
