clk: samsung: artpec-8: Add initial clock support for ARTPEC-8 SoC

2025-08-31T13:22:33+00:00

Add initial clock support for Axis ARTPEC-8 SoC which is required for enabling basic clock management. Add clock support for below CMU (Clock Management Unit) blocks in ARTPEC-8 SoC: - CMU_CMU - CMU_BUS - CMU_CORE - CMU_CPUCL - CMU_FSYS - CMU_IMEM - CMU_PERI Signed-off-by: Hakyeong Kim Signed-off-by: Varada Pavani Signed-off-by: SeonGu Kang Signed-off-by: Ravi Patel Link: https://lore.kernel.org/r/20250825114436.46882-4-ravi.patel@samsung.com Signed-off-by: Krzysztof Kozlowski

clk: samsung: add initial exynos7870 clock driver

2025-03-01T14:11:11+00:00

This is a basic implementation of the clock driver required by Samsung's Exynos7870 SoC. It implements CMU_MIF, CMU_DISPAUD, CMU_FSYS, CMU_G3D, CMU_ISP, CMU_MFCMSCL, and CMU_PERI. all other CMUs depend on CMU_MIF.

2025-03-01T14:08:11+00:00

CMU_TOP is the top level clock management unit which contains PLLs, muxes, dividers and gates that feed the other clock management units. CMU_ALIVE provides clocks for SPMI, the new MCT and other clock management units CMU_CMGP provides clocks for USI blocks CMU_HSI0 provides clocks for USB CMU_PERIC0 provides clocks for USI4 and I3C blocks CMU_PERIC1 provides clocks for USI blocks CMU_PERIC2 provides clocks for USI and I3C blocks CMU_PERIS provides clocks for GIC and the legacy MCT CMU_UFS provides clocks for UFS CMU_VTS provides clocks for other clock management units like CMU_AUD, which will be added in the future.

clk: samsung: add top clock support for ExynosAuto v920 SoC

2024-08-23T07:21:35+00:00

This adds support for CMU_TOP which generates clocks for all the function blocks such as CORE, HSI0/1/2, PERIC0/1 and so on. For CMU_TOP, PLL_SHARED0,1,2,3,4 and 5 will be the sources of this block and they will generate bus clocks.
