[PATCH net-next v6 0/3] dpll: add SiTime SiT9531x DPLL clock driver

[Ali Rouhi]

This series adds a DPLL subsystem driver for the SiTime SiT95316 and
SiT95317 I2C clock generators. Each device integrates four PLLs with
automatic/manual reference selection and on-chip TDC phase-offset
measurement, and is used for synchronization in telecom, networking,
and data-center timing.

The series contains the device-tree binding, the driver under
drivers/dpll/sit9531x/, and the MAINTAINERS entry.

v2: https://lore.kernel.org/netdev/20260520191943.73938-1-arouhi@xxxxxxxxxx/
v3: https://lore.kernel.org/netdev/20260731180951.65725-1-arouhi@xxxxxxxxxx/
v4: https://lore.kernel.org/netdev/20260806232439.27551-1-arouhi@xxxxxxxxxx/
v5: https://lore.kernel.org/netdev/20260810230439.22866-1-arouhi@xxxxxxxxxx/

Changes since v5 (driver only; the bindings are unchanged):

  - Read the input receiver-enabled state back from the device, so inputs
    are no longer all reported as disconnected after probe.
  - Fix the input priority table handling: it has 11 slots, not 12;
    correct the priority-slot to register-nibble mapping; and latch the
    table with a small update after a write.
  - Do not report an unused PLL as locked.
  - Report the reference fractional frequency offset through the .ffo_get
    callback (DPLL_FFO_PIN_DEVICE).
  - Read the DIVN the loop is actually running, and treat the DIVN
    numerator as a signed value.
  - Name the debug readback window for what it holds.
