Move the module_init/module_exit routines and the associated struct comedi_driver and other variables to the end of the source. This is more typical of how other drivers are written and removes the need for the forward declarations. Signed-off-by:

This helper function is used to fetch the comedi_device board_ptr which is used during the attach to pass board specific information to the comedi drivers. Signed-off-by:

(Life cycle of timed output device driver) 1) register the device as the timed output 2) enable() ops is called via the sysfs timeout > 0 : timer is activated and device is turned on timeout = 0 : timer is cancelled and device is off 3) unregister the timed output device if not used any more So the registered device should be disabled explicitly when the module is removed. ('disabled' means the timer is stopped and the device is turned off) Rather than implementing that code in each driver, just call enable() with timeout = 0 to clean up the driver.

This patch changes the name of function cfb_blank to smtc_blank. This function is not implemented like a generic function for frame buffer. Having the old prefix becomes confused when reading fb_ops structs. Tested with SM712 Signed-off-by:

With this patch smtcfb_info becomes the main structure to reach/handle state. fb_info struct links this struct via its private data field. This change improves encapsulation in functions. It reduces the number of arguments used in signatures too. Tested with SM712 Signed-off-by:

Generalize naming to allow other frequency synthesis techniques as well. No functional changes. Signed-off-by:
-
Lars-Peter Clausen authored
Currently we use two different naming schemes in the IIO API, iio_verb_object and iio_object_verb. E.g iio_device_register and iio_allocate_device. This patches renames instances of the later to the former. The patch also renames allocate to alloc as this seems to be the preferred form throughout the kernel. In particular the following renames are performed by the patch: iio_put_device -> iio_device_put iio_allocate_device -> iio_device_alloc iio_free_device -> iio_device_free iio_get_trigger -> iio_trigger_get iio_put_trigger -> iio_trigger_put iio_allocate_trigger -> iio_trigger_alloc iio_free_trigger -> iio_trigger_free The conversion was done with the following coccinelle patch with manual fixes to comments and documentation. <smpl> @@ @@ -iio_put_device +iio_device_put @@ @@ -iio_allocate_device +iio_device_alloc @@ @@ -iio_free_device +iio_device_free @@ @@ -iio_get_trigger +iio_trigger_get @@ @@ -iio_put_trigger +iio_trigger_put @@ @@ -iio_allocate_trigger +iio_trigger_alloc @@ @@ -iio_free_trigger +iio_trigger_free </smpl> Signed-off-by:

Previously, the touchscreen and ADC drivers of the LPC32xx SoC had a Kconfig conflict declared because they use the same hardware. Upon the introduction of device tree support in both drivers, the conflict must be removed to enable the same kernel to support different hardware (configured via the device tree). Signed-off-by:

This moves the VME core, VME board drivers, and VME bridge drivers out of the drivers/staging/vme/ area to drivers/vme/. The VME device drivers have not moved out yet due to some API questions they are still working through, that should happen soon, hopefully.

Take the core support + the kfifo buffer implentation out of staging. Whilst we are far from done in improving this subsystem it is now at a stage where the userspae interfaces (provided by the core) can be considered stable. Drivers will follow over a longer time scale. Signed-off-by:

There is one device supported by the driver which is not listed in the Kconfig help test. This patch adds it. Also we are past the point were we can possible fit all devices supported by the driver in the Kconfig entry title, so just list the initial device that was supported by this driver and note that similar devices are supported as well.

We can not read back the value from the device, but we cache the value anyway so we might as well return the cached value instead of an error. Signed-off-by:

The devices supported by this drivers only have a single shift register, which contains both the power down mode and the output sample. So writing the power down mode and the output sample can be done by the same function. Call this function prepare_write as it will prepare the spi message for a write. Also introduce a small helper function which performs the whole write by calling the chip the specific prepare function followed by a spi_sync. The two power down bits are always placed ontop of the msb of the output sample, so we can easily calculate their position by adding the channels shift to the channels realbits. Signed-off-by:

We currently only write 16 bit in case where we should write 24 bit. The spi message length is calculated from the channel storage_size, but since the storage size is only 16 bit we end up with the wrong value for devices which have power down bits and thus a register with 24 bit. Since each store function knows how many bytes it has to write just use the spi_write function from there instead of going through the hassle of manually preparing a spi_message and keeping buffers in the state struct. Another advantage of this patch is that it will make implementing support for similar I2C based DACs much easier. Signed-off-by:

AD5620_LOAD and AD5446_LOAD are both 0, so all these three functions are identical and we can replace them with only one. Signed-off-by:

Both the powerdown mode bits and the sample value are stored in the same register, so writing a sample while the device is powered down will clear the power down bits. To avoid this only update the cached value when the device is powered down. Signed-off-by:
