Thank you for your contribution! Sashiko AI review found 1 potential issue(s) to consider:
- [Medium] The device tree binding schema incorrectly applies GS101-specific PMIC constraints to the Exynos850 compatible string, preventing Exynos850 from legally defining its own PMIC child nodes.

dt-bindings: firmware: google,gs101-acpm-ipc: document Exynos850 compatible

This commit adds a new compatible string, samsung,exynos850-acpm-ipc, to the
ACPM IPC binding for the Exynos850 SoC. The hardware block requires a dedicated
compatible string due to differences in the initialization data base offset.

Does this introduce a regression by unintentionally applying GS101-specific
PMIC constraints to the Exynos850 hardware?

Looking at the rest of the binding schema, pmic-1 is constrained to
samsung,s2mpg10-pmic and pmic-2 is constrained to samsung,s2mpg11-pmic. With
additionalProperties set to false at the top level and no conditional blocks
to distinguish between compatible strings, an Exynos850 device tree cannot
legally define its own hardware-specific PMIC child nodes without failing
schema validation.

Should there be conditional blocks to ensure the GS101 PMIC constraints only
apply when google,gs101-acpm-ipc is used?
