To improve the accuracy of the reported VCO frequency perform all multiplications before divisions. This reduces rounding errors and makes sure the reported rates are accurate down to the last digit. Signed-off-by:

The driver doesn't actually rely on any DT properties. Removing this check makes it usable on ACPI based platforms. Signed-off-by:

Use wait_for_completion_timeout instead of wait_for_completion_interuptible_timeout. The interruptible variant gets constantly interrupted if a user program is compiled with the -pg option. The killable variant was not used due to the fact that a second program, reading on this device, that gets killed is then also killing that wait. Signed-off-by:

This commit will enable the interrupts of all channels handled by this driver only once in the probe function. This will improve performance because one byte less has to be written over i2c on each read out of the adc. On the fastest ADC mode this will improve read out speed by 15%. Signed-off-by:

In some cases, the wait_completion got interrupted. This caused the error-handling to mutex_unlock the function. The before turned on interrupt then got called anyway. In the ISR then completion() was called causing wrong adc-values returned in a following adc-readout. Reinitialise completion struct to make sure the counter is zero when beginning a new adc-conversion. Signed-off-by:

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.
