MSMCOBALT v2 uses different open-loop fuse reference voltages
than MSMCOBALT v1. Update the cpr3-mmss-regulator driver so that
it uses the proper set of reference voltages for v1 and v2. Also
change the compatible string of existing MSMCOBALT
cpr3-mmss-regulator devices to be for v1 explicitly so that the
v2 reference voltages are not erroneously used on v1 boards.

UFS clock scaling might start kicking in even before the device
is running at the fastest interface speed which is undesirable.
This change moves the clock scaling kick start only after the
device is detected and running at the fastest interface speed.

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.

When edid mixer control is executed, if the hdmi ops is

This error is treated as fatal by the caller.
Fix by returning valid mixer control info when hdmi ops

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.

Use separate notifier for cpu dying callback. This way we can give
higher priority to this notifier. That will make sure that etm disable
code gets executed before etm save register code during cpu power
collapse and etm's registers restore code gets executed before etm
enable code while cpu is coming back online.

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.

hyp_assign_table() is a costly operation during which nonsecure interrupts
are disabled. Split this operation into multiple parts for better
real-time behavior.
Splitting is done by the following criteria:
maximum number of physically contiguous memory regions
maximum total memory size.
Here is a chart showing the average performance of hyp_assign_table() with
N physically contiguous chunks each with size X.
#chunks chunk_size(pages) total_memory(pages) time(ms)
2 1 2 3.354
2 4 8 12.979
2 512 1024 4.349
8 1 8 4.714
8 4 32 26.781
8 512 4096 8.724
32 1 32 17.093
32 4 128 50.700
32 512 16384 26.717
128 1 128 71.076
128 4 512 126.305
Based on the above, select a maximum of 32 chunks or 512 total pages
as the limits.

Allocate objects via kzalloc() when possible. For the case where a large
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.
