Subject: [RFC PATCH 1/2] dt-bindings: soc: qcom: Add SDPM clock monitor driver documentation in yaml
Date: Fri, 2 Apr 2021 12:29:06 +0530 [thread overview]
Message-ID: <1617346747-8611-2-git-send-email-manafm@codeaurora.org> (raw)
In-Reply-To: <1617346747-8611-1-git-send-email-manafm@codeaurora.org>
Add yaml documentation for SDPM clock monitor driver which will
register for clock rate change notification and writes the clock rate
into SDPM CSR register.

+description: |
+
+ SDPM is used to monitor the operating frequency of different clocks and based
+ on operating levels of different clients, RDPM (Rail Digital Power Meter)
+ hardware estimates total power consumption of a shared railway. The SDPM
+ clock monitor driver will register with the clock framework for rate change
+ notification of different clocks. These clock rate will be updated to SDPM.
