With small channel spacing values and high reference frequencies it is possible to exceed the range of the 10-bit counter. Workaround by checking the range and widening some constrains. We don't use the REG1_PHASE value in this case the datasheet recommends to set it to 1 if not used.

2012-07-09iio: Introduce iio_validate_scan_mask_onehotLars-Peter Clausen
Add a helper function for validating a scan mask for devices where exactly one channel must be selected during sampling. This is a common case among devices which have scan mask restrictions so it makes sense to provide this function in the core. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2012-07-09iio: Add callback to check whether a scan mask is validLars-Peter Clausen
This is useful for cases where the number of valid scan masks grows exponentially, but it is rather easy to check whether a mask is valid or not programmatically. An example of such a case is a device with multiple ADCs where each ADC has a upstream MUX, which allows to select from a number of physical channels. +-------+ +-------+ | | | | --- Channel 1 | ADC 1 |---| MUX 1 | --- ... | | | | --- Channel M +-------+ +-------+ . . . . . . . . . +-------+ +-------+ | | | | --- Channel M * N + 1 | ADC N |---| MUX N | --- ... | | | | --- Channel M * N + M +-------+ +-------+ The number of necessary scan masks for this case is (M+1)**N - 1, on the other hand it is easy to check whether subsets for each ADC of the scanmask have only one bit set.

2012-07-08iio: Fix unitialized use of listSascha Hauer
The dev_attr list is initialized in __iio_add_event_config_attrs which is called only when indio_dev->channels is true. Nevertheless the list is used unconditionally later in iio_device_register_eventset which results in a NULL pointer exception. To fix this unconditionally initialize the list in iio_device_register_eventset. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2012-07-08iio: iio_buffer_register: Use correct channel when calculating masklengthLars-Peter Clausen
The channel set assigned to the iio device is not necessarily the same has the channel set passed to iio_buffer_register. So to avoid possible complications always work with the channel set pass to iio_buffer_register and ignore the channel set assigned to the iio device.

2012-07-08iio:trigger: Register sysfs file staticallyLars-Peter Clausen
The name sysfs attribute is the same for all triggers, so there is no need to register them dynamically at runtime. Create a attribute group for it and set it up for the bus attribute group. This also avoids a possible race condition where the uevent for the device is sent before the name sysfs attribute has been added.

2012-06-30iio:dac:ad5064: Add support for the ad5629r and ad5669rLars-Peter Clausen
The ad5629r and ad5669r are the I2C variants of the ad5628 and ad5668. Since the ad5064 driver currently only supports SPI based devices the major part of this patch focuses on adding support for I2C based devices. Adding support for the actual parts boils down to adding entries for them to the device id table.

Use to_iio_trigger(dev) instead of dev_get_drvdata(dev). Both will return the trigger which belongs to the device, but the the first on is a bit more lightweight. Since this is the last location where we used dev_get_drvdata() for retrieving the trigger there is no need anymore to assign the the trigger to the devices drvdata, so we can remove that as well.

It is not always the case that all channels can be used in buffered mode.

2012-06-15iio: buffer: Fix NULL pointer deref caused by empty scan maskLars-Peter Clausen
iio_scan_mask_match() returns NULL if the passed in scan mask is empty. This will happen if no channel has been selected and buffer is enabled. iio_sw_buffer_preenable() will assign NULL to indio_dev->active_scan_mask in this case. As a result iio_update_demux() will cause a NULL pointer deref, because it expects active_scan_mask to be non-NULL. Since it does not make much sense to start data capture if there is no data to capture this patch updates the code to fail gracefully in iio_scan_mask_match() instead of crashing the kernel.
