mfd: rk808: Add RK805 support

2017-08-21T07:54:20+00:00

The RK805 chip is a Power Management IC (PMIC) for multimedia and handheld
devices. It contains the following components:

    - Regulators
    - RTC
    - Clocking

Both RK808 and RK805 chips are using a similar register map,
so we can reuse the RTC and Clocking functionality.

mfd: constify regmap_irq_chip structures

2017-02-13T09:29:44+00:00

Declare regmap_irq_chip structures as const as they are only stored
in the regmap_irq_chip field of a rk808 structure. This field is of
type const, so regmap_irq_chip structures having this property can be
made const too.
Done using Coccinelle:

@r disable optional_qualifier@
identifier x;
position p;
@@
static struct regmap_irq_chip x@p={...};

@ok@
struct rk808 a;
identifier r.x;
position p;

mfd: rk808: RK818 uses DEV_OFF to power off supplies

2016-11-29T08:21:24+00:00

DEV_OFF and DEV_OFF_RST functions for RK808 are designed error that
only DEV_OFF_RST can power off supplies. RK818 has been fixed this
issue, so that DEV_OFF is used to power off supplies.

mfd: rk808: Use devm_mfd_add_devices() for mfd_device registration

2016-04-19T06:55:59+00:00

Use devm_mfd_add_devices() for MFD devices registration and remove
the call of mfd_remove_devices() from .remove callback to remove
MFD child-devices. This is done by managed device framework.

mfd: rk808: Disable the under voltage detect

2015-03-12T09:07:10+00:00

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.
