From a73edd3ed8d3c633be4fbe101ae9756222249a5f Mon Sep 17 00:00:00 2001 From: Peng Fan Date: Fri, 12 Jun 2026 16:46:27 +0800 Subject: [PATCH] clk: scmi: Introduce common header for SCMI clock interface Added a new header file 'clk-scmi.h' to define common structures and interfaces for the SCMI clock driver. This header will also be used by OEM-specific extensions to ensure consistency and reusability. Moved relevant structure definitions from the driver implementation to 'clk-scmi.h' to facilitate shared usage.
