I applied your patches to the following kernel: github.com/RobertCNelson/bb-kernel.git branch am33x-v4.8 Changing #define REG_DMAENABLE_CLEAR 0x038 to #define REG_DMAENABLE_CLEAR 0x03C Also applying the following DTS changes: target = <>; __overlay__ {

2016-09-21 Thread Mugunthan V N
The ADC has a 64 work depth fifo length which holds the ADC data till the CPU reads. So when a user program needs a large ADC data to operate on, then it has to do multiple reads to get its buffer. Currently if the application asks for 4 samples per channel with all 8 channels are enabled, kernel
