Subject: [PATCH v2 0/5] Add XSPI clocks and improve divider clock handling for R9A09G077 SoC

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@...renesas.com>

Hi All,

This patch series introduces support for the XSPI core and module clocks
in the Renesas R9A09G077 SoC. It also enhances the existing divider clock
registration process by utilizing device-managed helper functions and
ensuring proper propagation of rate changes to parent clocks.
Additionally, it adds necessary clock definitions for XSPI0/1 to the
device tree bindings for both R9A09G077 and R9A09G087 SoCs.

v1->v2 changes:
- In the fifth patch, added a custom divider clock type for XSPI clocks
  to enforce hardware constraints on supported operating rates.
- In the fourth patch, added Acked-by and Reviewed-by tags.
- Added three new patches 1-3.

Cheers,
Prabhakar
