[PATCH v2 2/4] iio: adc: xilinx: limit pcap clock frequency value

2018-07-23 Thread Manish Narani
This patch limits the xadc pcap clock frequency value to be less than 200MHz. This fixes the issue when zynq is booted at higher frequency values, pcap crosses the maximum limit of 200MHz(Fmax) as it is derived from IOPLL. If this limit is crossed it is required to alter the WEDGE and REDGE bits of
