In case of secure PIL, the PIL ops are very similar among
different subsystems.
For init_image, mem_setup, auth_and_reset and shutdown ops,
the PIL drivers follow the standard sequence to call into TZ
with the corresponding subsystem's pas id.
For proxy_vote and proxy_unvote ops, different subsystems share
the similar pattern of voting gdsc, regulators, clocks and bus
bandwidth.
Similarly, the SSR ops are common across different subsystems
as well.
Therefore, a generic TZ PIL and SSR driver is introduced to
provide a uniform way to manage PIL and SSR. The data and resources
information corresponding to the PIL and SSR ops for each subsystem
are contained in each subsystem's device tree node.

irqchip_init initializes irq controllers declared with IRQCHIP_DECLARE
macro. Enable the option that declares qpnp-int and gpio irq chips using
IRQCHIP_DECLARE. Consequently, remove all the instances of irq_init in
machine declarations - the kernel initialization code calls irqchip_init()
when init_irq callback is missing in the machine descriptor. This way
there is no need to create a match table of irq controllers and call
their initialization functions in the board file.

The CPUBW HW monitor devfreq governor uses the Krait L2 PM counters to
determine the bandwidth needed by the Krait CPU subsystem. This governor
can be used in conjunction with the CPUBW devfreq device to dynamically
scale the DDR frequency based on the demand/actual usage from the Krait CPU
subsystem. Since this governor uses the Krait L2 PM counters it can
conflict with certain profiling tools.
The Krait L2 performance monitor counters have the capability to count the
no. of read/write transactions going out the master ports. They also have
the capability to raise interrupts when they overflow. This driver uses
those counters to determine the true usage of DDR from the Krait processor
subsystem and then recommends CPU DDR BW votes based on the measured values
and the following tunable parameters.
The driver provides various tunables that allow it to be tuned more in
favor of power or performance:
- io_percent: The percentage of the CPU time that can be spent waiting on
memory I/O. Lower value is better performance and worse power.
- sample_ms: The sampling period in milliseconds. This only affects the
sampling period when DDR use is ramping down or is increasing very slowly
(See tolerance_percent).
- tolerance_percent: The minimum increase in DDR use, compared to previous
sample, that will trigger an IRQ to immediately bump up the bandwidth
vote. It's expressed as a percentage of the previous sampled DDR use.
- decay_rate: The parameter controls the rate at which the history is
forgotten when ramping down. This is expressed as a percentage of history
to be forgotten. So 100% means ignore history, 0% mean never forget the
historical max. The default 90% means forget 90% of history each time.
- guard_band_mbps: This is a margin that's added to the measured BW (and
hence also the Bus BW votes) that's present to account for the time it
takes to ramp up the DDR BW while the CPU continues to use the DDR.
- bw_step: All BW votes are rounded up to multiples of bw_step. The default
value is 200 MB/s that turns out to ~25 or 12.5 MHz based on the SoC. A
smaller value would mean more frequent bus BW changes. A higher value
would mean less frequent BW vote updates, but also means at times an
unnecessarily higher BW vote (due to the rounding up).

The MSM CPUfreq devfreq governor determines the CPU to DDR bandwidth vote
based on the current CPU frequency of all the active CPUs.
This functionality used to be a part of the MSM CPUfreq driver that
directly voted for the CPU to DDR bandwidth using MSM bus scaling APIs.
This refactor decouples CPU to DDR BW scaling from CPU frequency and allows
switch between various CPU BW governors.
The bandwidth values in the msm-cpufreq table have to be updated since the
new CPU BW driver does the MBps to Bps conversion correctly. The MSM
CPUfreq driver used to do * 1000 * 1000 to convert from MBps to Bps instead
of doing * 1024 * 1024.

governors to make CPU to DDR IB/AB bandwidth votes. This driver allows the

master ports or DDR slave ports, the actual port numbers, the system
topology, the available DDR frequencies, etc.

directory into the drivers/regulator directory. Also rename it
from rpm-regulator-smd.c to rpm-smd-regulator.c so that it
matches the naming scheme of the other regulator drivers. Moving
this driver out of the arch/arm/mach-msm directory allows it to
be shared with architectures other than 'arm'.
Also move the header file from the arch/arm/mach-msm/include/mach
directory into the include/linux/regulator directory. Moving the
header file requires updating all drivers which include it.

This change removes source files from the kernel tree that
were not being used during make. The list of used files
was generated using an annotated make log and was then
compared with new files added since the public release of
kernel version 3.10.00. New files which were added but
not used have been removed from the tree.
A diff was also run to determine the list of files that had
been modified since the release of kernel version 3.10.00.
These files were then scrubbed based on the current kernel
configuration, removing invalid and unused conditionals.
Some files which support planned functionality or are
useful in debugging have been excluded from this reap.
