From 2b7a02c322922a37cc5fc15d055b794cc2193062 Mon Sep 17 00:00:00 2001 From: Yixun Lan Date: Fri, 19 Dec 2025 21:52:08 +0800 Subject: [PATCH 1/3] clk: spacemit: prepare common ccu header In order to prepare adding clock driver for new K3 SoC, extract generic code to a separate common ccu header file, so they are not defined in K1 SoC-specific file, and then can be shared by all clock drivers.

In order to prevent the reset driver breakage, this commit is necessary as a post-fix for changes introduced by two patches below, and should be merged with them to make the patch series runtime bisectable.
