Merge tag 'samsung-drivers-firmware-clk-6.19' of https://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux into clk-samsung
Pull Samsung clk driver updates from Krzysztof Kozlowski:
Extend Samsung ACPM (Alive Clock and Power Manager) firmware drivers:
- Add support for passing DVFS (Dynamic Voltage and Frequency) messages
to configure the clocks in ACPM device.
- Add Exynos ACPM clock driver, which exposes to Linux several clocks
handled by the ACPM (firmware)
* tag 'samsung-drivers-firmware-clk-6.19' of https://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux:
firmware: exynos-acpm: add empty method to allow compile test
MAINTAINERS: add ACPM clock bindings and driver
clk: samsung: add Exynos ACPM clock driver
firmware: exynos-acpm: register ACPM clocks pdev
firmware: exynos-acpm: add DVFS protocol
dt-bindings: firmware: google,gs101-acpm-ipc: add ACPM clocks
