This series adds support for the AXI PWM GEN subsystem found on FPGA IP
cores. It can be used to generate up to four configurable PWM outputs,
and includes options for external synchronization and clock signals.
The work is being done on behalf of, and therefore lists maintainers
from Analog Devices, Inc.

The series has been tested on actual hardware using an EVAL-AD7985FMCZ
evaluation board. An oscilloscope was used to validate that the
generated PWM signal matched the requested one.
