real_fcc is the remaining capacity in the battery when the charger
driver indicates that the battery is fully charged. This value needs
to be calculated when charging ends with a fully charged battery.
The userspace can read this value via module parameter and preserve it
between restarts.
The real reason for calculating this is to indicate how much the battery
capacity has dropped w.r.t the profiled battery data use this deviation
in calculations.

kgsl now supports the use of 2 types of MMU. One is

This change add usb system clock support to OTG Driver.
System clock is a 60MHZ input clock to the USB ChipIdea core.
This clock is required starting from MDM9615.
This change also removes the enforcement for using a phy_reset_clk
for reseting the PHY. Starting from MDM9615, PHY reset is not implemented.
The core is reset together with the PHY using "usb_hs_clk" signal.

Clock pause message informs all devices on the bus that the active
manager having framer device pause the bus. This allows stopping the
clock to conserve power.
Clock is paused only if there are no active data channels on the bus
and no response is pending for any READ message.
Slimbus framework wakes up the controller using a wakeup function
pointer. Controller should then program the active framer to be out of
clock pause.

The reset interrupt in the pmic indicates the pmic will shutdown
the msm in few seconds - it does so by lowering the reset_n line
to the msm.
When this interrupt is triggered it is required that no more ssbi
transactions are initiated and the msm should cleanup and prepare
for the impending shutdown. There is no need to lower ps_hold in
this case as the pmic will shutdown the msm regardless.
Also since we don't want any ssbi transactions, force shutdown
nonboot cpus. This will prevent ssbi transactions to the pmic for
lower/raising nonboot cpu's voltages as they enter/exit idle states.

Create a regulator driver to control all regulators on the Qualcomm
PM8018 PMIC chip. This chip contains several different types of
regulators with a wide range of abilities and voltage ranges.
Five different regulator types are available on the PM8018.
PLDO - PMOS low drop out linear regulator
NLDO - NMOS low drop out linear regulator
NLDO1200 - 1.2A NMOS LDO (different control structure than other LDOs)
SMPS - switched-mode power supply
VS - voltage switch
The driver interfaces with the PMIC using Qualcomm's SSBI bus.
Calls to this bus are abstracted through the pm8xxx_readb/writeb API.

TSENS V2 supports reading from multiple sensors and
notifiying clients when the lower/upper thresholds
are reached. The lower/upper threshold use the last
sensors threshold that are set through the thermal sysfs.
TSENS HW is enabled only when the main sensor is requested.
The TSENS block is disabled if the main senors is disabled
irrespective of any other sensors that are being enabled.
When TSENS receives notification on temperature threshold
being reached, it checks and sends events to the sensors
that are enabled and whose thresholds are above the upper
or below the lower thresholds set in the tsens threshold
register.

The delay before the chip can be accessed after reset varies between different
chips in maXTouch family. Waiting for 200ms and then monitoring the CHG (chip
is ready when the line is low) is guaranteed to work with all chips.
v4: Adjust delay depending on the family ID of the chip. Also add a readback
of command register after backup is issued, to make sure we are not
proceeding
too fast there.
v3: Add a check for NULL read_chg() function, and add the read_chg() to platform
files using this driver (currently only mach-goni.c)
v2: At Dmitry's suggestion, add a timeout so we are not stuck looping
endlessly in case the CHG is not going low.
