e449829951 usb: phy: qusb: reset size to zero before getting next property size
For emulation platform, there are multiple PHY init sequence passed
through device tree. On some platform all PHY init sequence is not
required. This results into using zero as value and offset with PHY
init sequence which is not passed through device tree as of_get_property()
doesn't update size variable if property is not found. Hence reset size
variable to zero before querying next property size.

3087c5f20d PM / devfreq: memlat: Add a core to memory frequency mapping table
Add a core to memory frequency mapping table, which establishes
a relationship between the core frequency and its corresponding
bandwidth vote.

The governor expects a "qcom,core-dev-table" table as part of a given
memlat hardware monitor's device tree node.

This table is read upon registration of the memlat governor. The table
is then used to determine the memory bandwidth vote corresponding to the
maximum of the core frequencies.

b3f54ff633 msm: msm_bus: allow QoS clocks to be specified at mas nodes
Allow for greater granularity of QoS clocks enabled when
enabling clocks for QoS configuration for each node. Current
implementation requires all QoS clocks related to the parent
fab to enabled, which works well for mass QoS programming at
probe time, but turns on unnecessary clocks when QoS programming
defers at initial client request. This fixes an issue where
Camera's initial client vote also caused the toggling of mdss
gdscs which created a deadlock situation where the notifier
callback from MDSS GDSC tries to obtain the same lock held by
Camera's call in the same thread.

860afad94d ion: system_secure_heap: Change IOC_DRAIN work_struct to delayed_work
The video client signals to ion that it is done using an amount of memory
using the ioctl ION_IOC_DRAIN. However, the video client may have
previously shared this memory with other clients, such that the reference
count on existing ion_buffers is greater than one. Work around this issue
for now by assuming that the ion_buffers will be freed by the other users
within a short duration after the video client makes the ION_IOC_DRAIN
call.

641a99ef2f msm: secure_buffer: Limit continuous time spent in hypervisor
hyp_assign_table() is a costly operation during which nonsecure interrupts
are disabled. Split this operation into multiple parts for better

maximum total memory size.

Here is a chart showing the average performance of hyp_assign_table() with

ff15045bed secure_buffer: Remove all-in-one buffer usage

chunk (512 Kb) of physically contiguous memory is required, continue to use
a special purpose buffer reserved at boot. Since this special purpose
buffer is no longer used for random metadata, the associated code is
simpler to understand.

85635da429 qcom-charger: smb138x: fix buck damage on v1.1 hardware
Buck damage was observed because the OOB comparator activated
when HSFET was on, causing a direct short from VBUS to ground. Fix this
on V1.1 by increasing the OOB comparator threshold. On 2.0 this is fixed
by ensuring the OOB comparator activates only after HSFET minimum on
time. This in turn guarantees that HSFET and LSFET won't be on at the
same time.

Since the driver needs to detect the version of the smb, make use of the
qpnp-revid module.

61f82846e0 input: touchscreen: send WAKEUP event properly in ITE Tech driver
Send WAKEUP event properly in ITE Tech touch driver when device
is in suspend mode.
The driver maintins a boolean state for sending the WAKEUP event.
When user taps the screen for touch-to-wake feature, the irq
handler for ITE Tech touch driver is scheduled after the ITE tech
resume function. Due to this the boolean state gets reset.
So this change handles this use case properly.

This is a propagation patch from 3.18 kernel  'commit 25af9ff9bc39
("input: touchscreen: send WAKEUP event properly in ITE Tech driver")'

6f13460739 NFC: Fix unbalanced irq warning stack trace
When NFC is not enabled, IRQ will be disabled and
then if we do suspend/resume wake up functionality
won't be enabled at suspend but we try to disable
the same at resume and cause irq warning.

Fix warning trace in below cases :
1) NFC enabled in makefile, but manually turned off in
   settings menu (NFC driver is enabled and hw is present).
2) NFC is not enabled in makefile
   (NFC driver is enabled and hw is present).
