This patch is trying to cleanup for good the buffers operation functions. There is no need of using preenable, all can be done into postenable. Let's also rename the goto label using operation to perform and not where it fails. Note, not stable material. This is cleaning up the logic flow rather than fixing a bug. Signed-off-by:

Support for ad7616 running in software was added. In order to activate the software mode, HW_RNGSEL pins must be pulled low. Oversampling and input ranges are now configured in corresponding registers. Ad7616 has multiple scale options when it is configured in software mode. Also, in order to support multiple devices in software mode, the spi calculation of registers address must be generic. Because the length of address and bit which specifies the read/write operation is different for every device, calculation of address was made generic. Signed-off-by:

According to datasheet, ad7616 require at least 15ms after a restart to fully reconfigure and being able to receive new commands via spi. Signed-off-by:

Because software mode and register access are only available in spi, they were moved in spi file and are accessbile via bops structure. The write_os/scale will be overwritten by sw_mode_config function. This patch was made in order to support devices in software mode without making the driver dependent to spi and increase the abstraction of the core. Signed-off-by:

The common channel definition which are going to be used by both core file but also spi file, were moved in header file. Some devices have different channel definitions when are used in software mode, feature available only with spi, and those definitions will be added in spi file. Signed-off-by:

The mounting matrix for sensors was introduced in commit dfc57732 ("iio:core: mounting matrix support") However the device tree bindings are very terse and since this is a widely applicable property, we need a proper binding for it that the other bindings can reference. This will also be useful for other operating systems and sensor engineering at large. I think all 3D sensors should support it, the current situation is probably that the mounting information is confined in magic userspace components rather than using the mounting matrix, which is not good for portability and reuse.

Embedded controller return minimum and maximum frequencies, unfortunately we have no way to know the step for all available frequencies. Even if not complete, we can return a list of known values using the standard read_avail callback (IIO_CHAN_INFO_SAMP_FREQ) to provide them to userland. Now cros_ec_* sensors provides frequencies values in sysfs like this: "0 min max". 0 is always true to disable the sensor. Default frequencies are provided for earlier protocol. Signed-off-by:

This change adds device-tree bindings for the ADIS16460. Signed-off-by:
-
Alexandru Ardelean authored
The ADIS16460 device is a complete inertial system that includes a triaxial gyroscope and a triaxial accelerometer. It's more simplified design than that of the ADIS16480, and does not offer the triaxial magnetometers & pressure sensors. It does also have a temperature sensor (like the ADIS16480). Since it is part of the ADIS16XXX family, it re-uses parts of the ADIS library. Naturally, the register map is different and much more simplified than the ADIS16480 subfamily, so it cannot be integrated into that driver. A major difference is that the registers are not paged. One thing that is particularly special about it, is that it requires a higher delay between CS changes (i.e. when CS goes up, the spec recommends that it be brought down after a minimum of 16 uS). Other ADIS chips require (via spec) a minimum of 2 uS between CS changes. The kernel's 10 uS default should be fine for those other chips; they haven't been tested with lower CS change delays yet.

The ADIS16460 requires a higher delay before the next transfer. Since the SPI framework supports configuring the delay before the next transfer, this driver will become the first user of it. The support for this functionality in ADIS16460 requires an addition to the ADIS lib to support the `cs_change_delay` functionality from the SPI subsystem. Signed-off-by:

Some devices need to be configured with special bit in order to use spi 3-wire. This was done during device identification phase. Instead, let's move this part as spi specific. Doing this the check_device_support function becomes a simple device id check, so let's rename it. Signed-off-by:
