Subject: [PATCH v4 0/7] clk: axi-clk-gen: misc updates to the driver

These patches synchronize the driver with the current state in the
Analog Devices Linux tree:
  https://github.com/analogdevicesinc/linux/

They have been in the tree for about 2-3, so they did receive some
testing.

Highlights are:
* Add support for fractional dividers (Lars-Peter Clausen)
* Enable support for ZynqMP (UltraScale) (Dragos Bogdan)
* Support frequency limits for ZynqMP (Mathias Tausen)
  - And continued by Mircea Caprioru, to read them from the IP cores

Changelog v3 -> v4:
* added patch 'clk: axi-clkgen: wrap limits in a struct and keep copy on the state object'
  this resets the rest of the patch-set to adapt to adjusting the limits
  on per-clock instance versus being global to the entire driver
  Recommended-by: Moritz Fischer <mdf@...nel.org>

Changelog v2 -> v3:
* https://lore.kernel.org/linux-clk/20200924065012.59605-1-alexandru.ardelean@analog.com/
* for patch 'include: fpga: adi-axi-common.h: add definitions for supported FPGAs'
  - fix whitespace found by checkpatch
  - add 'Acked-by: Moritz Fischer <mdf@...nel.org>'

Changelog v1 -> v2:
- https://lore.kernel.org/linux-clk/20200804110658.40911-1-alexandru.ardelean@analog.com/
- in patch 'include: fpga: adi-axi-common.h: add definitions for supported FPGAs'
  * converted enums to #define
  * added Intel FPGA definitions
  * added Device-Package definitions
  * added INTEL / XILINX in the define names
 definitions according to:
