[PATCH v3 0/8] clk: clocking-wizard: Add static-config clock provider support

[Shubhrajyoti Datta]

 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.

 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


Changes in v3:
Added reviewed tag
the number of outputs duplication removed
Split notifier into per-clock callbacks

Changes in v2:
Merged the similar patches
Allow check for current dt even if it is unused.
Patch added
