staging: iio: Drop ADIS16060 driver from staging

2018-06-10T10:52:31Z

This part has been declared "not for new designs". It is now difficult to obtain and we have had no-one come forward with hardware making it difficult to proceed with the necessary work to move this driver out of staging. The device uses two separate chip selects and would require locking between them which is thought to be difficult to enforce without non trivial changes in the SPI subsystem. This work simply isn't worth doing given the status of the part and the fact no one seems to have gone for a similar hardware design since this one. If anyone does have access to one of these and is willing to contribute the time necessary then we can reevaluate dropping the driver. Signed-off-by: Jonathan Cameron

The equivalent of this is now done via macro magic when the relevant register call is made. The actual structure elements will shortly go away. Signed-off-by: Jonathan Cameron Reviewed-by: Lars-Peter Clausen

iio: gyro: adis16060: Change the name of function.

2017-04-02T08:10:32Z

Change the name of function from adis16060_spi_write_than_read() to adis16060_spi_write_then_read(). change "than" to "then" as its time depended. Signed-off-by: simran singhal Signed-off-by: Jonathan Cameron

staging: iio: adis16060: Remove iio_dev mlock and refactor code

2017-03-23T19:43:03Z

The IIO subsystem is redefining iio_dev->mlock to be used by the IIO core only for protecting device operating mode changes. ie. Changes between INDIO_DIRECT_MODE, INDIO_BUFFER_* modes. In this driver, mlock was being used to protect hardware state changes. In the driver, buf_lock protects both the adis16060_spi_write() and adis16060_spi_read() functions and both are always called in pair. First write, then read. Refactor the code to have one single function adis16060_spi_write_than_read() protected by the buf_lock. This removes the need for additional locking via mlock, so this locking is removed.

staging: iio: gyro: Remove & on function name to conform to similar IIO drivers

2017-03-13T21:20:38Z

Remove & from function pointers to conform to the style preferred in IIO. (Note that this is fine in staging drivers, but would create too much churn to do outside of staging, unless otherwise working on a driver).

spi: Drop owner assignment from spi_drivers

2015-10-27T05:49:09Z

We need to check adis16060_spi_read return code to avoid feeding user space with bogus data. While, at it introduce out_unlock label in order to simplify locking on error path. Signed-off-by: Cristina Moraru Signed-off-by: Greg Kroah-Hartman
