* iio:adc:max1363 support SMBus for 8-bit devicesVivien Didelot2013-10-201-19/+57
| | | | | | | | | | | | | | | | The driver currently supports only I2C access. But supported devices with an accuracy of 8-bit are compatible with the SMBus byte access routines. This patch wraps the send and receive routines depending on the chip accuracy and fonctionnalities of its adapter. For instance, this allows us to use a MAX11603 on a ICH7 controller. This patch also simplifies the max1363_write_basic_config() routine to use the struct max1363_state fields directly.

* | iio: at91: introduce touch screen support in iio adc driverJosh Wu2013-10-171-24/+364
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | AT91 ADC hardware integrate touch screen support. So this patch add touch screen support for at91 adc iio driver. To enable touch screen support in adc, you need to add the dt parameters: 1. which type of touch are used? (4 or 5 wires), sample period time. 2. correct pressure detect threshold value. In the meantime, since touch screen will use a interal period trigger of adc, so it is conflict to other hardware triggers. Driver will disable the hardware trigger support if touch screen is enabled. This driver has been tested in AT91SAM9X5-EK and SAMA5D3x-EK.

* | iio: Update buffer's bytes per datum after updating the scan maskLars-Peter Clausen2013-10-161-1/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently a IIO device driver needs to make sure to update the buffer's bytes per datum after the scan mask has changed. This is usually done in the preenable callback by invoking iio_sw_buffer_preenable(). This is something that needs to be done and is done for virtually all devices which support buffers (we currently have only one exception). Also this a bit of a layering violation since we have to call the buffer setup ops from the device setup ops. This requires the device driver to know about the internal requirements of the buffer (e.g. whether we need to call the set_bytes_per_datum) callback. And especially with in-kernel buffer consumers, which allows to attach arbitrary buffers to a device, this is something that the driver can't know. Moving this to the core allows us to drop the individual calls to iio_sw_buffer_preenable() from drivers.

| | | | | | | | | | | | | | | | | | | | | | update_needed is used to decide whether the kfifo buffer needs to be re-allocated. It is set to true whenever the size of the buffer is changed. It is never set to false though, causing the buffer to always be re-allocated. Setting update_needed to false after the new buffer has been allocated fixes the problem.

* | iio:kfifo: Empty buffer on updateLars-Peter Clausen2013-10-151-5/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The kfifo's request_update callback will free the current buffer and allocate a new one if the size has changed. This will remove any samples that might still be left in the buffer. If the size has not changed the buffer content is left untouched though. This is a bit inconsistent and might cause an application to see data from a previous capture. This patch inserts a call to kfifo_reset_out() when the size did not change. This makes sure that any pending samples are removed from the buffer. Note, due to a different bug the buffer is currently always re-allocated, even if the size did not change. So this patch will not change the behavior. In the next patch the bug will be fixed and this patch makes sure that the current behavior is kept.

* | iio:kfifo: Protect against concurrent access from userspaceLars-Peter Clausen2013-10-151-5/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It is possible for userspace to concurrently access the buffer from multiple threads or processes. To avoid corruption of the internal state of the buffer we need to add proper locking. It is possible for multiple processes to try to read from the buffer concurrently and it is also possible that one process causes a buffer re-allocation while a different process still access the buffer. Both can be fixed by protecting the calls to kfifo_to_user() and kfifo_alloc() by the same mutex. In iio_read_first_n_kfifo() we also use kfifo_recsize() instead of the buffers bytes_per_datum to avoid a race that can happen if bytes_per_datum has been changed, but the buffer has not been reallocated yet. Note that all access to the buffer from within the kernel is already properly synchronized, so there is no need for extra locking in iio_store_to_kfifo().

* | iio: Extend the event config interfaceLars-Peter Clausen2013-10-121-22/+171
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The event configuration interface of the IIO framework has not been getting the same attention as other parts. As a result it has not seen the same improvements as e.g. the channel interface has seen with the introduction of the channel spec struct. Currently all the event config callbacks take a u64 (the so called event code) to pass all the different information about for which event the callback is invoked. The callback function then has to extract the information it is interested in using some macros with rather long names. Most information encoded in the event code comes straight from the iio_chan_spec struct the event was registered for. Since we always have a handle to the channel spec when we call the event callbacks the first step is to add the channel spec as a parameter to the event callbacks. The two remaining things encoded in the event code are the type and direction of the event. Instead of passing them in one parameter, add one parameter for each of them and remove the eventcode from the event callbacks. The patch also adds a new iio_event_info parameter to the {read,write}_event_value callbacks. This makes it possible, similar to the iio_chan_info_enum for channels, to specify additional properties other than just the value for an event. Furthermore the new interface will allow to register shared events. This is e.g. useful if a device allows configuring a threshold event, but the threshold setting is the same for all channels. To implement this the patch adds a new iio_event_spec struct which is similar to the iio_chan_spec struct. It as two field to specify the type and the direction of the event. Furthermore it has a mask field for each one of the different iio_shared_by types. These mask fields holds which kind of attributes should be registered for the event. Creation of the attributes follows the same rules as the for the channel attributes. E.g. for the separate_mask there will be a attribute for each channel with this event, for the shared_by_type there will only be one attribute per channel type. The iio_chan_spec struct gets two new fields, 'event_spec' and 'num_event_specs', which is used to specify which the events for this channel. These two fields are going to replace the channel's event_mask field. For now both the old and the new event config interface coexist, but over the few patches all drivers will be converted from the old to the new interface. Once that is done all code for supporting the old interface will be removed. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
