Subject: [PATCH 1/2] dt-bindings: clock: samsung: Document Exynos850 CMU_APM
Date: Thu, 21 Oct 2021 23:31:51 +0300	[thread overview]
Message-ID: <20211021203152.29312-1-semen.protsenko@linaro.org> (raw)

CMU_APM generates clocks for APM IP-core (Active Power Management). In
particular it generates RTC clocks, which are needed to enable rtc-s3c
driver on Exynos850 SoC.
