[PATCH v2] dt-bindings: clock: Add Amlogic A9 SCMI clock controller

[Jian Hu via B4 Relay <devnull+jian.hu.amlogic.com@kernel.org>]

From: Jian Hu <jian.hu@amlogic.com>

Add the SCMI clock controller dt-bindings for the Amlogic A9 SoC family.

Signed-off-by: Jian Hu <jian.hu@amlogic.com>

Changes in v2:
- Split the A9 clock driver and send the SCMI clock separately.
  The A9 PLL introduces several new features, and the Meson PLL framework
  needs to be refactored to support them. Since this work requires more
  time and there is no hard dependency between the different A9 clock
  controllers, split out the A9 clock driver and submit it separately to
  ease review.
- Link to v1: https://lore.kernel.org/all/20260511-b4-a9_clk-v1-1-41cb4071b7c9@amlogic.com/
