[PATCH 4.9 11/38] mfd: twl4030-power: Fix pmic for boards that need vmmc1 on reboot

[Greg Kroah-Hartman]

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Adam Ford <aford173@xxxxxxxxx>

commit ad48ed0c5763dc08931407e455dff5acdbe96e81 upstream.

At least two different omap3630/3730 boards booting from MMC1
fail to reboot if the "ti,twl4030-power-idle-osc-off" or
"ti,twl4030-power-idle" compatible flags are set.  This patch will
keep the vmmc1 powered up during reboot allowing the bootloader
to load.
