During board initialization read the shared memory item
SMEM_POWER_ON_STATUS_INFO and place it in the procfs at
/proc/sys/kernel/boot_reason
The data item is an integer with a bit being set to identify the reason
the device was powered on. The values of this data item is defined in
the document Document/arm/msm/boot.txt, the following is the data in the
documentation file.
power_on_status values set by the PMIC for power on event:
----------------------------------------------------------
0x01 -- keyboard power on
0x02 -- RTC alarm
0x04 -- cable power on
0x08 -- SMPL
0x10 -- Watch Dog timeout
0x20 -- USB charger
0x40 -- Wall charger
0xFF -- error reading power_on_status value
This is cherrypicked from commit <372d39f87b0da75>
("put reason for boot in procfs") of 3.18 tree.

The IBB pulse-skip and NLIMIT DAC configuration should be disabled
before applying the 2nd SWIRE command skip logic, to guarantee
that the IBB voltage changes immediately in the subsequent
SWIRE command. After the WA is completed, the pulse-skip can
be re-enabled after a programmable delay. Add this logic and
a DT property 'qcom,swire-ibb-ps-enable-delay' to configure
this delay. If this delay is not specified in the DT it defaults

are controlled by the parent device, and handlers are registered by the

The I2C PMIC Controller is used by multi-function PMIC devices which
communicate over the I2C bus. The controller enumerates all child nodes
as platform devices, and instantiates a regmap interface for them to
communicate over the I2C bus.
The controller also controls interrupts for all of the children platform
devices. The controller handles the summary interrupt by deciphering which
peripheral triggered the interrupt, and which of the peripheral interrupts
were triggered. Finally, it calls the interrupt handlers for each of the
virtual interrupts that were registered.

This change adds the use of devfreq to MMC.
Both eMMC and SD card will use it.
For some workloads, such as video playback, it isn't
necessary for these cards to run at high speed.
Running at lower frequency, for example 52MHz, in such
cases can still meet the deadlines for data transfers.
Scaling down the clock frequency dynamically has power
savings not only because the bus is running at lower frequency
but also has an advantage of scaling down the system core
voltage, if supported.
Provide an ondemand clock scaling support similar to the
cpufreq ondemand governor having two thresholds,
up_threshold and down_threshold to decide whether to
increase the frequency or scale it down respectively.
The sampling interval is in the order of milliseconds.
If sampling interval is too low, frequent switching of
frequencies can lead to high power consumption and if
sampling interval is too high, the clock scaling logic
would take long time to realize that the underlying
hardware (controller and card) is busy and scale up
the clocks.
