Subject: [PATCH 2/2] clk: samsung: acpm: add initial Exynos850 support
Date: Tue, 12 May 2026 21:40:49 +0100 [thread overview]
Message-ID: <20260512-exynos850-acpm-clk-v1-2-837532ddbf38@linaro.org> (raw)
In-Reply-To: <20260512-exynos850-acpm-clk-v1-0-837532ddbf38@linaro.org>
The Exynos850 SoC utilizes the APM co-processor for clock management
via ACPM, similar to the GS101 SoC.
Add the Exynos850-specific clock variant array (including mif, int,
cpucl0, cpucl1, g3d, aud, cam, disp, and cp) and wire it up to the
driver data infrastructure. Add the "exynos850-acpm-clk" device ID
to enable dynamic instantiation of these clocks during probe().
