iio:imu:adis: Move exports into IIO_ADISLIB namespace

2022-02-18T11:42:26Z

In order to avoid unneessary pollution of the global symbol namespace move the common/library functions into a specific namespace and import that into the various specific device drivers that use them.

iio: adis: handle devices that cannot unmask the drdy pin

2021-10-19T07:27:34Z

Some devices can't mask/unmask the data ready pin and in those cases each driver was just calling '{dis}enable_irq()' to control the trigger state. This change, moves that handling into the library by introducing a new boolean in the data structure that tells the library that the device cannot unmask the pin. On top of controlling the trigger state, we can also use this flag to automatically request the IRQ with 'IRQF_NO_AUTOEN' in case it is set. So far, all users of the library want to start operation with IRQs/DRDY pin disabled so it should be fairly safe to do this inside the library.

iio: core: move @id from struct iio_dev to struct iio_dev_opaque

2021-05-17T12:49:13Z

Continuing from Alexandru Ardelean's introduction of the split between driver modifiable fields and those that should only be set by the core. This could have been done in two steps to make the actual move after introducing iio_device_id() but there seemed limited point to that given how mechanical the majority of the patch is. Includes fixup from Alex for missing mxs-lradc-adc conversion.

iio:imu:adis: Use IRQF_NO_AUTOEN instead of irq request then disable

2021-04-07T07:36:39Z

This is a bit involved as the adis library code already has some sanity checking of the flags of the requested irq that we need to ensure is happy to pass through the IRQF_NO_AUTOEN flag untouched. Using this flag avoids us autoenabling the irq in the adis16460 and adis16475 drivers which cover parts that don't have any means of masking the interrupt on the device end. Note, compile tested only!

iio: adis_trigger: Remove code to set trigger parent

2021-03-25T19:13:50Z

iio_trigger_set_drvdata() sets the trigger device parent to first argument of viio_trigger_alloc(), no need to do it again in the driver code. Remove adis_trigger_setup() to match other drivers where setting the trigger is usually done in the probe() routine.

iio: imu: adis: Add irq flag variable

2020-04-25T15:09:30Z

There are some ADIS devices that can configure the data ready pin polarity. Hence, we cannot hardcode our IRQ mask as IRQF_TRIGGER_RISING since we might want to have it as IRQF_TRIGGER_FALLING. Signed-off-by: Nuno Sá Signed-off-by: Jonathan Cameron

iio: imu: adis: Add Managed device functions

2020-04-25T15:08:06Z

This patch adds support for a managed device version of adis_setup_buffer_and_trigger. It works exactly as the original one but it calls all the devm_iio_* functions to setup an iio buffer and trigger. Hence we do not need to care about cleaning those and we do not need to support a remove() callback for every driver using the adis library. Signed-off-by: Nuno Sá Signed-off-by: Jonathan Cameron
