Subject: [PATCH v5 5/5] clk: samsung: exynos990: Add DPU_BUS and CMUREF mux/div and update CLKS_NR_TOP
Date: Sat, 30 Aug 2025 16:28:42 +0000	[thread overview]
Message-ID: <20250830-fix-cmu-top-v5-5-7c62f608309e@gmail.com> (raw)
In-Reply-To: <20250830-fix-cmu-top-v5-0-7c62f608309e@gmail.com>

Add DPU_BUS and CMUREF mux/div, wire their registers and parents,
and update CLKS_NR_TOP. These use the new IDs appended to the
bindings to avoid ABI changes.
