Subject: [PATCH v5 2/5] clk: samsung: exynos990: Fix CMU_TOP mux/div bit widths
Date: Sat, 30 Aug 2025 16:28:39 +0000 [thread overview]
Message-ID: <20250830-fix-cmu-top-v5-2-7c62f608309e@gmail.com> (raw)
In-Reply-To: <20250830-fix-cmu-top-v5-0-7c62f608309e@gmail.com>
Correct several mux/div widths (DSP_BUS, G2D_MSCL, HSI0 USBDP_DEBUG,
HSI1 UFS_EMBD, APM_BUS, CPUCL0_DBG_BUS, DPU) to match hardware.
Fixes: bdd03ebf721f ("clk: samsung: Introduce Exynos990 clock controller driver")
