Subject: [PATCH v8 10/15] dt-bindings: arm: Document qcom,kpss-gcc
Date: Tue, 27 Feb 2018 19:36:57 +0530	[thread overview]
Message-ID: <1519740422-3835-11-git-send-email-sricharan@codeaurora.org> (raw)
In-Reply-To: <1519740422-3835-1-git-send-email-sricharan@codeaurora.org>

From: Stephen Boyd <sboyd@codeaurora.org>

The ACC and GCC regions present in KPSSv1 contain registers to
control clocks and power to each Krait CPU and L2. Documenting
the bindings here.
