2019-04-27staging: comedi: comedi_isadma: Use a non-NULL device for DMA APIIan Abbott2-2/+18
The "comedi_isadma" module calls `dma_alloc_coherent()` and `dma_free_coherent()` with a NULL device pointer which is no longer allowed. If the `hw_dev` member of the `struct comedi_device` has been set to a valid device, that can be used instead. Unfortunately, all the current users of the "comedi_isadma" module leave the `hw_dev` member set to NULL. In that case, fall back to using the comedi "class" device pointed to by the `class_dev` member if that is non-NULL. In that case, make it "DMA-capable" with a coherent DMA mask set to the ISA bus limit of 16MB (24 bits).

This patch adds support for the Generic Counter interface to the 104-QUAD-8 driver. The existing 104-QUAD-8 device interface should not be affected by this patch; all changes are intended as supplemental additions as perceived by the user. Generic Counter Counts are created for the eight quadrature channel counts, as well as their respective quadrature A and B Signals (which are associated via respective Synapse structures) and respective index Signals. The new Generic Counter interface sysfs attributes are intended to expose the same functionality and data available via the existing 104-QUAD-8 IIO device interface; the Generic Counter interface serves to provide the respective functionality and data in a standard way expected of counter devices.

2019-04-25counter: Introduce the Generic Counter interfaceWilliam Breathitt Gray8-0/+2148
This patch introduces the Generic Counter interface for supporting counter devices. In the context of the Generic Counter interface, a counter is defined as a device that reports one or more "counts" based on the state changes of one or more "signals" as evaluated by a defined "count function." Driver callbacks should be provided to communicate with the device: to read and write various Signals and Counts, and to set and get the "action mode" and "count function" for various Synapses and Counts respectively. To support a counter device, a driver must first allocate the available Counter Signals via counter_signal structures. These Signals should be stored as an array and set to the signals array member of an allocated counter_device structure before the Counter is registered to the system. Counter Counts may be allocated via counter_count structures, and respective Counter Signal associations (Synapses) made via counter_synapse structures. Associated counter_synapse structures are stored as an array and set to the the synapses array member of the respective counter_count structure. These counter_count structures are set to the counts array member of an allocated counter_device structure before the Counter is registered to the system. A counter device is registered to the system by passing the respective initialized counter_device structure to the counter_register function; similarly, the counter_unregister function unregisters the respective Counter. The devm_counter_register and devm_counter_unregister functions serve as device memory-managed versions of the counter_register and counter_unregister functions respectively.

2019-04-22iio: trigger: stm32-timer: fix build issue when disabledFabrice Gasnier1-1/+10
This fixes a build issue when CONFIG_IIO_STM32_TIMER_TRIGGER isn't set but used in stm32-dfsdm-adc driver (e.g. CONFIG_STM32_DFSDM_ADC is set): ERROR: "is_stm32_timer_trigger" [drivers/iio/adc/stm32-dfsdm-adc.ko] undefined! There are two possible options to fix this issue: - select IIO_STM32_TIMER_TRIGGER along with CONFIG_STM32_DFSDM_ADC. This is what's being done currently for CONFIG_STM32_ADC. - stub "is_stm32_timer_trigger" function Choice is made to stub this function as suggested in [1]. This is also inspired by similar "is_stm32_lptim_trigger" function (see [2]) in include/linux/iio/timer/stm32-lptim-trigger.h [1] https://www.mail-archive.com/linux-kernel@vger.kernel.org/msg1977377.html [2] https://lkml.org/lkml/2017/9/10/124 Fixes: 11646e81d775 ("iio: adc: stm32-dfsdm: add support for buffer modes") Reported-by: Randy Dunlap <rdunlap@infradead.org> Fix-suggested-by: Jonathan Cameron <jic23@kernel.org> Signed-off-by: Fabrice Gasnier <fabrice.gasnier@st.com> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>
