Subject: [PATCH v2 5/7] arm64: dts: qcom: msm8998-xperia: Configure display boost regulators
Date: Thu,  9 Sep 2021 14:37:31 +0200	[thread overview]
Message-ID: <20210909123733.367248-5-angelogioacchino.delregno@somainline.org> (raw)
In-Reply-To: <20210909123733.367248-1-angelogioacchino.delregno@somainline.org>

Add configuration for the LAB and IBB regulators (in boost mode):
this platform has smartphones with three different display sizes,
hence different displays requiring different voltage.

The common configuration parameters have been put in the common
device-tree, while specific voltage specs and soft-start-us are
variant specific, so they have been put into the machine specific
dts file.
