Clk_prepare_enable and clk_disable_unprepare combine clk_prepare and clk_enable, and clk_disable and clk_unprepare. They make the code more concise, and ensure that clk_unprepare is called when clk_enable fails. A simplified version of the semantic patch that introduces calls to these functions is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression e; @@ - clk_prepare(e); - clk_enable(e); + clk_prepare_enable(e); @@ expression e; @@ - clk_disable(e); - clk_unprepare(e); + clk_disable_unprepare(e); // </smpl> Signed-off-by:

By bypassing the standard macros for setting up the kfifo we can take advantage of the fixed record size implementation without having to have a type to pass in (from which the size of an element is normally established). In IIO we have variable 'scans' as our records in which any element can be present or not. They do not however vary when we are actually filling or reading from the buffer. Thus we have a fixed record size whenever we are actually running. As setup and tear down are not in the fast path we can take the overhead of reinitializing the kfifo every time. Signed-off-by:

Convert the ad7780 driver to make use of the new common code for devices from the Analog Devices Sigma Delta family. As a bonus the ad7780 driver gains support for buffered mode. Although this is a bit tricky. The ad7780 reports in the lower 4 unused bits of the data word the internal gain used. The driver will update the scale attribute value depending on the gain accordingly, but obviously this will only work if the gain does not change while sampling. This is not perfect, but since we store the raw value in the buffer an application which is aware of this can extract the gain factor from the buffer as well an apply it accordingly. Signed-off-by:

Most devices from the Analog Devices Sigma Delta family use a similar scheme for communication with the device. This includes register access, as well as trigger handling. But each device sub-family has different features and different register layouts (some even have no registers at all) and thus it is impractical to try to support all of the devices by the same driver. This patch adds a common base library for Sigma Delta converter devices. It will be used by individual drivers. This code is mostly based on the three existing Sigma Delta drivers the AD7192, AD7780 and AD7793, but has been improved for more robustness and flexibility. Signed-off-by:

Introduce two new helper functions to attach a arbitrary pointer to a IIO device. This is useful to get access to external non-global data from within a IIO device callbacks where only the IIO device is available. Internally these functions use dev_{set,get}_drvdata() on the struct device embedded in the IIO device. Signed-off-by:
