Subject: [PATCH 2/3] clk: samsung: exynos990: Add LHS_ACEL gate clock for HSI0 and update CLK_NR_TOP
Date: Sun, 31 Aug 2025 11:36:27 +0000	[thread overview]
Message-ID: <20250831-usb-v1-2-02ec5ea50627@gmail.com> (raw)
In-Reply-To: <20250831-usb-v1-0-02ec5ea50627@gmail.com>

Add the LHS_ACEL gate clock to the HSI0 clock controller. This clock is
critical for USB functionality and mark it as critical to keep it
enabled and update CLK_NR_TOP.
