ARM: dts: imx6sl-evk: Keep VGEN1 regulator always enabled
On imx6sl-evk board the VGEN1 regulator powers up the NVCC_1P2V domain of the imx6sl SoC, so we need to keep it always powered. According to imx6sl datasheet the GPIO block has three supplies: NVCC33_IO, NVCC18_IO and NVCC_1P2V and it states that: "All digital I/O supplies (NVCC_xxxx) must be powered under normal conditions whether the associated I/O pins are in use or not" 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. Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com> Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
