This series adds support for the Exynos850 SoC to the Samsung ACPM
firmware IPC driver.

The Exynos850 contains an APM co-processor that handles IPC messages for
clocks, power, thermal management, and PMIC control. While it uses the
same underlying ACPM communication machinery and protocols set as
the GS101, the exact implementation details vary between the two SoCs.

Those protocol-specific differences will be managed individually by the
corresponding protocol drivers. However, a dedicated compatible string
is still required for the core IPC driver because the Exynos850 firmware
utilizes a different initialisation data base offset.

First patch updates the google,gs101-acpm-ipc dt-bindings to include the
new "samsung,exynos850-acpm-ipc" compatible string.

Second patch adds the corresponding match data, base offset, and clock
device name to the exynos-acpm firmware driver.

There is a dependency for driver changes (not for device tree bindings
update) on clk-acpm exynos850 series posted here:
