kernel/include/linux/mfd/rk808.h, branch linux-4.1.yHosts the 0x221E linux distro kernel.https://universe.0xinfinity.dev/distro/kernel/atom?h=linux-4.1.y2015-03-12T09:07:10Zmfd: rk808: Disable the under voltage detect2015-03-12T09:07:10ZChris Zhongzyw@rock-chips.com2015-02-28T10:09:06Zurn:sha1:e19f742885e87ab9582fdf5940f214419eb9275b
Rk808 has a under voltage detect function, when the voltage of buck is
under 85% the target voltage, the buck output will reset. But if the
power load is too heavy, this function maybe err, when current over
4.2A, although the voltage is normal, but RK808 mistakenly think it is
under 85%, and reset the buck. So let's disable this function.

The RK808 chip is a power management IC for multimedia and handheld
devices. It contains the following components:
- Regulators
- RTC
- Clkout
The RK808 core driver is registered as a platform driver and provides
communication through I2C with the host device for the different
components.
