Subject: [PATCH v4 2/4] ARM: dts: omap4-droid4: Update backlight dt properties
Date: Wed, 13 Mar 2019 07:32:47 -0500 [thread overview]
Message-ID: <20190313123249.17258-2-dmurphy@ti.com> (raw)
In-Reply-To: <20190313123249.17258-1-dmurphy@ti.com>

v4 - No change - https://lore.kernel.org/patchwork/patch/1050125/
v3 - updated keypad label on v1 comment - https://lore.kernel.org/patchwork/patch/1049023/
v2 - Fixed ramp-up and ramp-down properties, removed hard coded property values,
I did not change the label as it is undecided what it could be - https://lore.kernel.org/patchwork/patch/1048806/
