Subject: [PATCH 2/2] ARM: dts: imx6sx: Add 198MHz operating point
Date: Mon, 25 Apr 2016 16:38:48 -0300 [thread overview]
Message-ID: <1461613128-24001-2-git-send-email-festevam@gmail.com> (raw)
In-Reply-To: <1461613128-24001-1-git-send-email-festevam@gmail.com>
From: Fabio Estevam <fabio.estevam@nxp.com>
198MHz is a valid operating point for mx6sx.
Add entries for VDD_ARM_CAP and VDD_SOC_CAP voltages for 198MHz according
to the imx6sx datahseet:
http://cache.nxp.com/files/32bit/doc/data_sheet/IMX6SXIEC.pdf
(a 25mV offset is added to the minimum allowed values for safety).
These values also match the ones from the NXP kernel.
