[PATCH 1/4] arm64: defconfig: enable Exynos ACPM clocks

[Krzysztof Kozlowski]

From: Tudor Ambarus <tudor.ambarus@linaro.org>


Enable the Exynos ACPM clocks driver. Samsung Exynos platforms
implement ACPM to provide support for clock configuration, PMIC
and temperature sensors.

  dt-bindings: soc: samsung: exynos-pmu: allow mipi-phy subnode for Exynos7870 PMU (2025-11-05 08:20:21 +0100)

----------------------------------------------------------------
Samsung SoC drivers for v6.19

1. ChipID driver: Add support for identifying Exynos8890 and Exynos9610.

2. PMU driver: Allow specifying list of valid registers for the custom
   regmap used on Google GS101 SoC.  The PMU (Power Management Unit) on
   that SoC uses more complex access to registers than simple MMIO and
   invalid registers trigger aborts halting the system.

3. Few minor cleanups.

4. Several new bindings for compatible devices.

Samsung SoC firmware/clock drivers for v6.19

Extend Samsung ACPM (Alive Clock and Power Manager) firmware drivers:
1. Add support for passing DVFS (Dynamic Voltage and Frequency) messages
   to configure the clocks in ACPM device.

2. Add Exynos ACPM clock driver, which exposes to Linux several clocks
   handled by the ACPM (firmware).
