Subject: [RFC v2 08/11] arm64: dts: sdm845: Add ufs opps and power-domains
Date: Wed, 20 Mar 2019 15:19:15 +0530
Message-ID: <20190320094918.20234-9-rnayak@codeaurora.org> (raw)
In-Reply-To: <20190320094918.20234-1-rnayak@codeaurora.org>

Add the additional power domain and the OPP table for ufs on sdm845
so the driver can set the appropriate performance state of the
power domain while setting the clock rate.
