Ditch platform_data fields in favor of device tree properties for configuring EXCA and EXCB output pins and setting the capacitive channel excitation level. As this covers all current use cases for the platform_data struct, remove ad7746.h header file since it's no longer needed. Signed-off-by:

It happens that an ADC will only provide raw or processed voltage conversion channels. (adc/ab8500-gpadc.c). On the Samsung GT-I9070 this is used for a light sensor and current sense amplifier so we need to think of something. The idea is to allow processed channels and scale them with 1/1 and then the rescaler can modify the result on top.

Some supported devices support burst read function. This provides a method for reading a batch of data (status, temperature, gyroscopes, accelerometers, time stamp/data counter, and CRC code), which does not require a stall time between each 16-bit segment and only requires one command on the DIN line to initiate. Devices supporting this mode are: * adis16495-1 * adis16495-2 * adis16495-3 * adis16497-1 * adis16497-2 * adis16497-3 Reviewed-by:

Variable in_loc is being assigned a value from a calculation however the assignment is never read, so this redundant assignment can be removed.

The call to pm_runtime_put_noidle() in remove() callback is not balanced by any gets Note this doesn't cause any problems beyond reader confusion as the runtime pm core protects against the reference counter going negative.

The samples buffer is passed to iio_push_to_buffers_with_timestamp() which requires a buffer aligned to 8 bytes as it is assumed that the timestamp will be naturally aligned if present. Fixes tag is inaccurate but prior to that likely manual backporting needed (for anything before 4.18) Earlier than that the include file to fix is drivers/iio/common/cros_ec_sensors/cros_ec_sensors_core.h: commit 974e6f02 ("iio: cros_ec_sensors_core: Add common functions for the ChromeOS EC Sensor Hub.") present since kernel stable 4.10.

To make code more readable, use a structure to express the channel layout and ensure the timestamp is 8 byte aligned. Found during an audit of all calls of uses of iio_push_to_buffers_with_timestamp(). Fixes tag is not strictly accurate as prior to that patch there was potentially an unaligned write. However, any backport past there will need to be done manually. Fixes: 0624bf84 ("iio:tcs3472: Use iio_push_to_buffers_with_timestamp()") Signed-off-by:

Remove() callback calls pm_runtime_put_noidle() but there it is not balancing a get. No actual affect because the runtime pm core prevents the reference count going negative. Whilst here use pm_runtime_resume_and_get() rather than open coded version. Again, coccinelle script missed this one due to more complex code structure. Signed-off-by:

Calls to pm_runtime_put_noidle in probe() error path and remove() are not match to any get() calls.

probe() error paths after runtime pm is enabled, should disable it. remove() should not call pm_runtime_put_noidle() as there is no matching get() to have raised the reference count. This case has no affect a the runtime pm core protects against going negative. Whilst here use pm_runtime_resume_and_get() to tidy things up a little. coccicheck script didn't get this one due to complex code structure so found by inspection. Signed-off-by:
