Fix invalid usage of a list_for_each_entry cursor in
clk_notifier_unregister(). When list is empty or if the list
is completely traversed (without breaking from the loop on one
of the entries) then the list cursor does not point to a valid
entry and therefore should not be used. The patch fixes a logical
bug that hasn't been seen in pratice however it is analogus
to the bug fixed in clk_notifier_register().

Many moons ago, support was added to the SMI handlers to log s0ix entry
and exit. Early iterations of firmware on Apollo Lake correctly returned
"unsupported" for this new command they did not recognize, but
unfortunately also contained a quirk where this command would cause them
to power down rather than resume from s0ix.
Fixes for this quirk were pushed out long ago, so all APL devices still
in the field should have updated firmware. As such, we no longer need to
have the s0ix_logging_enable be opt-in, where every new platform has to
add this to their kernel commandline parameters. Change it to be on by
default.
In theory we could remove the parameter altogether: updated versions of
Chrome OS containing a kernel with this change would also be coupled
with firmware that behaves properly with these commands. Eventually we
should probably do that. For now, convert this to an opt-out parameter
so there's an emergency valve for people who are deliberately running
old firmware, or as an escape hatch in case of unforeseen regressions.

The shifting of the u8 integer buf[3] by 24 bits to the left will
be promoted to a 32 bit signed int and then sign-extended to a
u64. In the event that the top bit of buf[3] is set then all
then all the upper 32 bits of the u64 end up as also being set
because of the sign-extension. Fix this by casting buf[i] to
a u64 before the shift.

Sometimes the clients of nvmem just want to get a number out of
nvmem. They don't want to think about exactly how many bytes the nvmem
cell took up. They just want the number. Let's make it easy.
In general this concept is useful because nvmem space is precious and
usually the fewest bits are allocated that will hold a given value on
a given system. However, even though small numbers might be fine on
one system that doesn't mean that logically the number couldn't be
bigger. Imagine nvmem containing a max frequency for a component. On
one system perhaps that fits in 16 bits. On another system it might
fit in 32 bits. The code reading this number doesn't care--it just
wants the number.
We'll provide two functions: nvmem_cell_read_variable_le_u32() and
nvmem_cell_read_variable_le_u64().
Comparing these to the existing functions like nvmem_cell_read_u32():
* These new functions have no problems if the value was stored in
nvmem in fewer bytes. It's OK to use these function as long as the
value stored will fit in 32-bits (or 64-bits).
* These functions avoid problems that the earlier APIs had with bit
offsets. For instance, you can't use nvmem_cell_read_u32() to read a
value has nbits=32 and bit_offset=4 because the nvmem cell must be
at least 5 bytes big to hold this value. The new API accounts for
this and works fine.
* These functions make it very explicit that they assume that the
number was stored in little endian format. The old functions made
this assumption whenever bit_offset was non-zero (see
nvmem_shift_read_buffer_in_place()) but didn't whenever the
bit_offset was zero.
NOTE: it's assumed that we don't need an 8-bit or 16-bit version of
this function. The 32-bit version of the function can be used to read
8-bit or 16-bit data.
At the moment, I'm only adding the "unsigned" versions of these
functions, but if it ends up being useful someone could add a "signed"
version that did 2's complement sign extension.
At the moment, I'm only adding the "little endian" versions of these
functions. Adding the "big endian" version would require adding "big
endian" support to nvmem_shift_read_buffer_in_place().

QFPROM controller hardware requires 1.8V min for fuse blowing.
So, this change sets the voltage to 1.8V, required to blow the fuse
for qfprom-efuse controller.
To disable fuse blowing, we set the voltage to 0V since this may
be a shared rail and may be able to run at a lower rate when we're
not blowing fuses.

In case of error, the function pci_iomap() returns NULL pointer
not ERR_PTR(). The IS_ERR() test in the return value check
should be replaced with NULL test.

This patch series adds the SDM660 interconnect provider driver in
order to stop some timeouts and achieve some decent performance by
avoiding to be NoC limited.
It's also providing some power consumption improvement, but I have
only measured that as less heat, which is quite important when
working on thermally constrained devices like smartphones.
Please note that this driver's yaml binding is referring to a MMCC
clock, so this series does depend on the SDM660 MMCC driver that I
have sent separately.
The multimedia clock is required only for the Multimedia NoC (mnoc).
This patch series has been tested against the following devices:
- Sony Xperia XA2 Ultra (SDM630 Nile Discovery)
- Sony Xperia 10 (SDM630 Ganges Kirin)
- Sony Xperia 10 Plus (SDM636 Ganges Mermaid)

There is a link between the GEM NoC and C NoC nodes, which is currently
missing from the topology. Let's add it to allow consumers request paths
that use this link.

For creating an array with the members for each NoC, we should be using
a local indexes, as otherwise unnecessary large arrays would be created.
Using an incorrect indexes will also result error for the consumers when
they try to find a valid path between the endpoints. Let's fix this and
use the correct ids.

The input data of the ECB (AES) algorithm needs to be aligned
with 16 bytes, and the input data of the XTS (AES) algorithm is
at least 16 bytes. Otherwise the SEC hardware will go wrong.

HPRE can only deal with src_data smaller than 'p' in 'CURVE25519'
algorithm, but 'rfc7748' says:
'Implementations MUST accept non-canonical values and process them as
if they had been reduced modulo the field prime'
So we get its modulus to p, and then deal it with HPRE.

This patch changes nothing about functions except location in order to make
code logic clearly.
This adjustment follows three principles:
1.The called functions are listed in order above the calling functions.
2.The paired functions are next to each other.
3.Logically similar functions are placed in the same area. Here, we use
the callback of 'acomp_alg' as the basis for dividing areas.
