## Summary This commit adds two new IOCTL commnands for ADC driver. Command ANIOC_RESET_FIFO resets FIFO head and tail which causes the driver to wait for the new data to be received. Calling this command before reading ADC data in user space ensures that the read data are newly sampled. Command ANIOC_SAMPLES_ON_READ return the number of read channels in the buffer. This can be useful in nonblocking mode when the application needs to get the samples received before the app was started. Both IOCTL commands are used only in generic driver section only and do not have any effect on existing architecture specific drivers. ## Impact ADC driver, no impact for current applications. ## Testing Tested on Teensy 4.1 -- This is an automated message from the Apache Git Service.
