Subject: [PATCH 5/6] drm/msm/dsi: Update the "vdd" voltage range
Date: Mon, 15 Feb 2016 18:30:58 +0530	[thread overview]
Message-ID: <1455541259-8967-6-git-send-email-architt@codeaurora.org> (raw)
In-Reply-To: <1455541259-8967-1-git-send-email-architt@codeaurora.org>

The min and max voltage levels for the VDD input to DSI were initially set
to 2.85V (as suggested by the spec).

We have a platform (db410c) where the same regulator supply is also needed
by another consumer at a higher voltage. Bump up the max voltage level to
3.3V. No regressions are seen with this.
