Subject: [PATCH 3/4] arm64: dts: qcom: db820c: Add s2 regulator in pmi8994
Date: Wed, 18 Mar 2020 22:39:01 -0700	[thread overview]
Message-ID: <20200319053902.3415984-4-bjorn.andersson@linaro.org> (raw)
In-Reply-To: <20200319053902.3415984-1-bjorn.andersson@linaro.org>

From: Rajendra Nayak <rnayak@codeaurora.org>

Add the SPMI regulator node in the PMI8994, use it to give us VDD_GX
at a fixed max nominal voltage for the db820c and specify this as supply
for the MMSS GPU_GX GDSC.

With the introduction of CPR support the range for VDD_GX should be
expanded.
