The Xilinx clocking-wizard IP can be used in a static-config mode
where the hardware is pre-programmed at boot and no dynamic register
access is required. In that case the driver should skip ioremap,
read the fixed multiplier/divisor pairs from the device tree, and
register fixed-factor clocks derived from clk_in1.
Currently the xlnx,static-config is not functional as it doesnot
model the output clocks. The series fixes the same.
This series:
- adds the xlnx,clk-mul-div binding to carry mul/div pairs
- makes the reg property optional for static-config nodes
- skips ioremap when xlnx,static-config is present
- moves clk_in1 acquisition before the static-config check so it
is available in both code paths
- registers fixed-factor output clocks in static-config mode
