Subject: [PATCH v3 0/3] clk: si5351: add option to adjust PLL without glitches

This series intends to address a problem I had when using the Si5351A as
a runtime adjustable audio bit clock. The basic issue is that the driver
in its current form unconditionally resets the PLL whenever adjusting
its rate. But this reset causes an unwanted ~1.4 ms LOW signal glitch in
the clock output.

As a remedy, a new property is added to control the reset behaviour of
the PLLs more precisely. In the process I also converted the bindings to
YAML.

Changes:

v2 -> v3:

- address further comments from Rob:
  - drop unnecessary refs and minItems
  - simplify if conditions for chip variants
  - ignore his comment about dropping '|', as line would be >80 columns
  - move additionalProperties: false close to type: object
  - define clocks/clock-names at top-level
- drop patch to dove-cubox dts per Krzysztof's comment - will send
  separately
- collect Sebastian's Acked-by

v1 -> v2:

- address Rob's comments on the two dt-bindings patches
- new patch to correct the clock node names in the only upstream device
  tree using si5351

Alvin Šipraga (3):
  dt-bindings: clock: si5351: convert to yaml
  dt-bindings: clock: si5351: add PLL reset mode property
  clk: si5351: allow PLLs to be adjusted without reset
