[PATCH v2 0/2] dpll: zl3073x: add Microchip ZL30643 support

The Microchip ZL30643 (chip ID 0x0E3B) is a 3 DPLL channel member of
the ZL3064x timing family, register compatible with the
ZL30733 of the ZL3073x family.

Patch 1 describes it in the binding as a fallback to the register-
        equivalent microchip,zl30733.
Patch 2 adds the 0x0E3B runtime chip-ID table entry; no new match
        strings, the fallback binds via the existing microchip,zl30733
        entry.

Changes in v2:
- bindings: describe ZL30643 as a fallback to the ZL30733 instead of a
  standalone compatible (based on Conor's questions).
- driver: drop the SPI/I2C/of_match additions: the fallback binds via
  microchip,zl30733; keep only the 0x0E3B chip-ID table entry needed
  for the runtime channel-count lookup.
- commit messages: comments on the datasheets and identity backing
  the REF_PHASE_COMP_32 flag reuse (Ivan's questions).
- Link to v1: https://lore.kernel.org/r/20260724-for-upstream-zl30643-v1-0-ea93ba4d85c8@free.fr (local)
