Subject: [PATCH] ARM: dts: imx6sl-evk: Keep VGEN1 regulator always enabled
Date: Tue, 18 Feb 2014 16:40:04 -0300 [thread overview]
Message-ID: <1392752404-524-1-git-send-email-fabio.estevam@freescale.com> (raw)
On imx6sl-evk board the VGEN1 regulator powers up the NVCC_1.2V domain of the
imx6sl SoC, so we need to keep it always powered.
This problem has been observed by the fact that a GPIO connected to an LED could
not work when the PMIC driver was enabled.
Keeping VGEN1 regulator always enabled fixes the problem.
