Subject: [PATCH v7 1/3] dt-bindings: clock: Add YAML schemas for the QCOM MSS clock bindings
Date: Thu, 19 Mar 2020 11:05:29 +0530 [thread overview]
Message-ID: <1584596131-22741-2-git-send-email-tdas@codeaurora.org> (raw)
In-Reply-To: <1584596131-22741-1-git-send-email-tdas@codeaurora.org>
The Modem Subsystem clock provider have a bunch of generic properties
that are needed in a device tree. Add a YAML schemas for those.
Add clock ids for GCC MSS and MSS clocks which are required to bring
the modem out of reset.
