William Breathitt Gray authored
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.

This patch adds standard documentation for the userspace sysfs attributes of the Generic Counter interface. Reviewed-by:

William Breathitt Gray authored
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. Reviewed-by:

Clang warns: drivers/staging/kpc2000/kpc2000/cell_probe.c:96:38: warning: suggest braces around initialization of subobject [-Wmissing-braces] struct resource resources[2] = {0}; ^ {} drivers/staging/kpc2000/kpc2000/cell_probe.c:314:38: warning: suggest braces around initialization of subobject [-Wmissing-braces] struct resource resources[2] = {0}; ^ {} 2 warnings generated. One way to fix these warnings is to add additional braces like Clang suggests; however, there has been a bit of push back from some maintainers, who just prefer memset as it is unambiguous, doesn't depend on a particular compiler version, and properly initializes all subobjects [1][2]. Do that here so there are no more warnings.

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].
