Patch ad608fbcf1 changed how events were subscribed to address an issue
elsewhere. As a side effect of that change, the "add" callback was called
before the event subscription was added to the list of subscribed events,
causing the first event queued by the add callback (and possibly other
events arriving soon afterwards) to be lost.
Fix this by adding the subscription to the list before calling the "add"
callback, and clean up afterwards if that fails.

Plane input CSC needs to be enabled to convert frambuffers from
YUV to RGB. This is needed for bottom 3 planes on ICL, rest of
the planes have hardcoded conversion and taken care by the legacy
code.
This patch defines the co-efficient values for YUV to RGB conversion
in BT709 and BT601 formats. It programs the coefficients and enables
the plane input csc unit in hardware.
This has been verified and tested by Maarten and the change is working
as expecpted.
v2: Addressed Maarten's and Ville's review comments and added the
coefficients in a 2D array instead of independent Macros.
v3: Added individual coefficient matrix (9 values) instead of 6
register values as per Maarten's comment. Also addresed a shift
issue with B channel coefficient.
v4: Added support for Limited Range Color Handling
v5: Fixed Matt and Maarten's review comments.
v6: Added human readable matrix values for YUV to RGB Conversion along
with just the bspec register values, as per Matt's suggestion.
v7: Refactored the code, move csc coefficient programming function to
intel_sprite.c and made it static as per Ville's review comment.
v8: Addressed Ville's review comment. Called the coefficient programming
from within the skl_program_plane and used I915_WRITE_FW instead of
I915_WRITE.
v9: Fixed Ville's review comments.

In suspend to ram, we use the 'standby' instruction to emulate
power management device to hang the system util wakeup source
send wakeup events to break the loop.
First, we push the general purpose registers and system registers
to stack. Second, we translate stack pointer to physical address
and store to memory to save the stack pointer. Third, after write

This is the commit that porting the perf for nds32.
1.Raw event:
The raw events start with 'r'.
Usage:
perf stat -e rXYZ ./app
X: the index of performance counter.
YZ: the index(convert to hexdecimal) of events
Example:
'perf stat -e r101 ./app' means the counter 1 will count the instruction
event.
The index of counter and events can be found in
"Andes System Privilege Architecture Version 3 Manual".
Or you can perform the 'perf list' to find the symbolic name of raw events.
2.Perf mmap2:
Fix unexpected perf mmap2() page fault
When the mmap2() called by perf application,
you will encounter such condition:"failed to write."
With return value -EFAULT
This is due to the page fault caused by "reading" buffer
from the mapped legal address region to write to the descriptor.
The page_fault handler will get a VM_FAULT_SIGBUS return value,
which should not happens here.(Due to this is a read request.)
You can refer to kernel/events/core.c:perf_mmap_fault(...)
If "(vmf->pgoff && (vmf->flags & FAULT_FLAG_WRITE))" is evaluated
as true, you will get VM_FAULT_SIGBUS as return value.
However, this is not an write request. The flags which indicated
why the page fault happens is wrong.
Furthermore, NDS32 SPAv3 is not able to detect it is read or write.
It only know either it is instruction fetch or data access.
Therefore, by removing the wrong flag assignment(actually, the hardware
is not able to show the reason), we can fix this bug.
3.Perf multiple events map to same counter.
When there are multiple events map to the same counter, the counter
counts inaccurately. This is because each counter only counts one event
in the same time.
So when there are multiple events map to same counter, they have to take
turns in each context.
There are two solution:
1. Print the error message when multiple events map to the same counter.
But print the error message would let the program hang in loop. The ltp
(linux test program) would be failed when the program hang in loop.
2. Don't print the error message, the ltp would pass. But the user need to
have the knowledge that don't count the events which map to the same
counter, or the user will get the inaccurate results.
We choose method 2 for the solution

There exist two variants in the market using different displays
that are differentiated via their sku-id.
The bootloader on them also determines the correct devicetree to
load via the sku-id.
So add a common scarlet dtsi and two minimal board devicetrees
for the two display variants.

The slbfee instruction was only added in ISA 2.05 (Power6), it's not
supported on older CPUs. We don't have a CPU feature for that ISA
version though, so just use the ISA 2.06 feature flag.

Old toolchains don't know about slbfee and break the build, eg:
{standard input}:37: Error: Unrecognized opcode: `slbfee.'
Fix it by using the macro version. We need to add an underscore
version that takes raw register numbers from the inline asm, rather
than our Rx macros.

The code for assert_slb_exists() and assert_slb_notexists() is almost
identical, except for the polarity of the WARN_ON(). In a future patch
we'll need to modify this code, so consolidate it now into a single
function.

Add SH_PFC_PIN_CFG_IO_VOLTAGE definition for the SDHI pins
capable of switching voltage, also add pin groups and functions
for SDHI0 and SDHI1. Please note that with the RZ/G1C only 1
bit of the POC Control Register is used to control each interface.

Some VIN channels support less than 24 lanes. As union vin_data always
consumes space for 24 lanes, this wastes memory.
Hence introduce new smaller unions vin_data12 and vin_data16, to
accommodate VIN channels with only 12 or 16 lanes.
This reduces the static pin controller driver size by 320 bytes for
R-Car V2H, and by 96 bytes for R-Car E2.
