Subject: [PATCH 3/4] ARM: imx: add VDDSOC/PU setpoint info into dts
Date: Mon, 16 Dec 2013 16:14:09 -0500 [thread overview]
Message-ID: <1387228450-641-1-git-send-email-b20788@freescale.com> (raw)
i.MX6Q needs to update VDDARM, VDDSOC/PU regulator when CPUFreq
is changed, each setpoint has different voltage, so we need to
pass VDDARM, VDDSOC/PU's freq-voltage info from dts.
