ADC and TSC share an IRQ line. Patch one is simple and adds shared irq support on the TSC side. The second patch adds continuous sampling support to the am335x_adc driver. It has been submitted previously. This is round 3. Previously: - Submitted as a series of patches and bug fixes. - The driver would continuously push samples into a buffer exposed to userspace. - Extra sysfs attributes for selecting continuous mode or one shot mode. - No trigger functionality. - Reading from /dev/iio required patching the provided generic_buffer.c iio test application to bypass trigger. - Only one channel could be read at a time. - And even then, samples were skipped as the FIFO was read incorrectly. Now: - All bug fixes merged together in one patch. - Stuck closely to the IIO ABI this time. - Added trigger support. - Fixed channel scanning where only one channel could be read into the buffer at a time. - Now all enabled channels in the scan_elements folder are pushed to the userspace properly without skipping any samples. - generic_buffer.c test application can read samples without any modification. - A sysfs trigger starts acquisition. This has been tested on the Beaglebone Black running the am335x processor. The patches apply on the iio branch fixes-togreg.
