One of the main goals of the IPC Logging is to allow extracting logs
from memory dumps. The current implementation has the following
limitations:
1) if logs are being dumped through debugfs at the time of the crash,
it is not possible to extract logs that were already dumped
2) it is not always possible to tell the difference between empty,
partially full, and full log pages resulting in extraction
complications
3) if the system memory is not cleared between reboots, then the same
log ID and log page may be extracted leading to duplicate log
pages
Add additional debugfs read index, timestamps for log pages, and change
the read/write indices to easily differentiate between empty, partially
full, and full log pages.

2) trigger an interrupt to the remote processor (which may be Apps)
3) clients may now start writing to entries
If Apps does not process the interrupt in step 2 until after the client
writes to an entry (step 3), then Apps will not notify clients of the

The Shared Memory Point to Point (SMP2P) driver facilitates
communication of multiple 32-bit values between two processors. Each
value (called a state entry) has a single writer (the local side) and a
single reader (the remote side). Entries are uniquely identified in the
system by the directed edge (local processor ID to remote processor ID)
and a string identifier.
This driver, which is layered on top of shared memory (SMEM), will
eventually replace the existing broadcast implementation of SMSM. This
driver has several advantages over SMSM including:
* Point-to-point communication which allows for XPU protection of SMEM
* Multiple 32-bit state values for future expansion
* GPIO and Virtual interrupt support for client-facing API
* Version and feature negotiation to allow for phased upgrades of
a system without requiring cross-processor dependencies.

tspp: Improve data-path handling
Existing driver allocated BAM descriptor at fixed sizes each
with interrupt flag set. Notification on data was received when
the descriptor is fully consumed by the HW. The descriptor size
on one hand need to be big enough so that we don't receive too much
interrupts for high-bitrate streams, and on other hand needs
to be small enough so that for low-bitrate stream we are not starved
waiting for data for a long period of time.
The change adds support of allocating small descriptors and set
interrupt flags on part of descriptors. In addition, expiration
timer is used so that if interrupt is not received after long period
of time the timer handler reports back descriptors are already ready
to be consumed. This allows low-rate of interrupts and
handling of low-bitrate streams.
As descriptors are smaller now (size of single TS packet), exposed
API within SW demux that handles a single packet to save the function
call to the API that handles multiple packets for efficiency. Information
regarding the new buffer allocation was added to debugfs.

The demux is an in-kernel software component whose purpose is to take
an incoming TSIF stream and split it into multiple output channels
based on the PID field in each TS packet. Each output channel can be
used for a different purpose, such as audio, video or channel
information. In order to get good performance when moving such large
data streams around, the demux was placed in kernel-space as to
prevent copying memory buffers between kernel-space and user-space, at
least at this early stage in processing the traffic. Originally the
design of the TSPP driver was based on the earlier TSIF driver, so it
contained only a user-space API.

msm: Removed XPU violations.
During initialization, there is a violation in writing to
"read only" registers for targets that support trust zone.
Trustzone marks certain registers as read-only.
This change fixes the issue by writing to registers only
on targets that do not support trust zone.

Revert "msm: rng: Disable RNG init on APQ8064"
This reverts commit 46af59fb8f4bce302ad4d787b63b25e46548df6a.
The RNG driver was initially disabled because of missing clock
changes and this driver was causing boot up issues.
Now with the clock changes checked in the RNG driver works.

prng: Replace clk_enable and clk_disable APIs.
The clk driver has introduced new clock APIs that replace
the existing clk_enable and clk_disable.
-clk_enable() APIs is replaced with clk_prepare_enable().
-clk_disable() API is replaced with clk_disable_unprepare().

msm-rng: Fix PRNG_LFSR_CFG setup
Changes to only configure the LFSR on devices that don't have the
prng hardware already setup mistakenly removed the LFSR
configuration. Instead, the change is ORing in 1s into the top 16
bits of the register (they're marked as reserved).
Restore the original code by masking off the lower 16 bits of the
register and filling them with values from the
PRNG_LFSR_CFG_CLOCKS define.

msm: rng: Add support for iface clk
Currently the driver supports only enabling core_clk,but on
certain targets, iface_clk is used for the hardware RNG
block. This fix adds compatibility to targets that have iface
clock instead of the core clock.

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 change is a response to a customer request described in
JIRA KERNEL-518

Two platforms, bcm and exynos have their own firmware interfaces using
the "secure monitor call", this adds support for those.
We had originally planned to have a third set of patches in here, which
would extend support for the existing generic "psci" call that is used
on multiple platforms as well as Xen and KVM guests, but that ended up
getting dropped because the patches were not ready in time.

Pull ARM updates from Russell King:
"The major items included in here are:
- MCPM, multi-cluster power management, part of the infrastructure
required for ARMs big.LITTLE support.
- A rework of the ARM KVM code to allow re-use by ARM64.
- Error handling cleanups of the IS_ERR_OR_NULL() madness and fixes
of that stuff for arch/arm
- Preparatory patches for Cortex-M3 support from Uwe Kleine-König.
There is also a set of three patches in here from Hugh/Catalin to
address freeing of inappropriate page tables on LPAE. You already
have these from akpm, but they were already part of my tree at the
time he sent them, so unfortunately they'll end up with duplicate
commits"
