[PATCH v3 0/9] clk: clocking-wizard: add user clock monitor support

[Harry Austen]

Improve utilised clk/notifier APIs, making use of device managed versions
of functions, make dynamic reconfiguration support optional (because it is
in hardware) and add support for the clock monitor functionality added in
version 6.0 of the Xilinx clocking wizard IP core, through use of the
auxiliary bus and UIO frameworks.

The combined addition of all of these patches allows, for example, to use
the clocking wizard solely for its user clock monitoring logic, keeping
dynamic reconfiguration support disabled.

This is currently untested on hardware, so any help testing this would be
much appreciated!

v2 -> v3:
- Move kernel doc variable comment to bottom in clk_hw transition patch (2)
- Remove extra line (and add Krzysztof's R-b tag) in binding patch (5)
- Add Krzysztof's A-b tag to dynamic reconfig binding patch (8)
v1 -> v2:
- Split and improve clk_hw+devres transition patch (2+3)
- Fix/improve DT binding patches (5+8)
- Utilise auxiliary bus in monitor support patch (6)
- Add dedicated UIO driver for monitor support (7)
