[PATCH net-next v4 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, DCO frequency adjustment, 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.

v1: https://lore.kernel.org/netdev/20260511211143.19792-1-arouhi@xxxxxxxxxx/
v2: https://lore.kernel.org/netdev/20260520191943.73938-1-arouhi@xxxxxxxxxx/
v3: https://lore.kernel.org/netdev/20260731180951.65725-1-arouhi@xxxxxxxxxx/

Changes since v3:

  - No functional changes.  v3 was dropped from patchwork because a
    corporate mail-gateway appended a confidentiality footer in transit;
    that footer has been suppressed for the kernel lists and this resend
    is clean.
  - Rebased onto current net-next; base-commit recorded below.
