Subject: [PATCH v3 2/3] ARM: dts: imx6ull: add operating points
Date: Tue, 22 May 2018 08:28:52 +0200	[thread overview]
Message-ID: <20180522062853.24799-2-sebastien.szymanski@armadeus.com> (raw)
In-Reply-To: <20180522062853.24799-1-sebastien.szymanski@armadeus.com>

i.MX6ULL has different operating ranges than i.MX6UL so add the
operating points for the i.MX6ULL. A 25mV offset is added to the minimum
allowed values like for the i.MX6UL.

Signed-off-by: Sébastien Szymanski <sebastien.szymanski@armadeus.com>

Changes for v3:
 - none

Changes for v2:
 - Fix soc-operating-points voltage for 792MHz and 900MHz
