Align SYSC interrupt configuration in the legacy wrapper with the DT
version:
- Mask SYSC interrupt sources before enabling them (doesn't matter
much as they're disabled at the GIC level anyway),
- Make sure not to clear reserved SYSCIMR bits that were set before.

On R-Car H1 and Gen2, the SYSC interrupt registers are always configured
using hardcoded values in platform code. For R-Car Gen2, values are
provided for H2 and M2-W only, other SoCs are not yet supported, and
never will be.
Move this configuration from SoC-specific platform code to the
rcar_sysc_init() wrapper, so it can be skipped if the SYSC is configured
from DT. This would be the case not only for H1, H2, and M2-W using a
modern DTS, but also for other R-Car Gen2 SoCs not supported by the
platform code, relying purely on DT.
There is no longer a need to return the mapped register block, hence
make the function return void.

Let rcar_sysc_init() trigger initialization of the SYSC PM domains from
DT if called before the early_initcall.
On failure, it falls back to mapping the passed register block, as
before.

On success, rcar_sysc_pd_init() returns an uninitialized error code.
Use the return value of of_genpd_add_provider_onecell() to fix this.
This went unnoticed, as early_initcall() doesn't care about the return
value.

Add tblck to the pwm nodes. This insures that the ehrpwm driver has access
to the time-based clk.
Do not remove similar entries for ehrpwm node. Later patches will switch
from using ehrpwm node name to pwm. But to maintain ABI compatibility we
shouldn't remove the old entries.

- A patch series including both cpuidle and FEC driver changes to
disable deeper idle states when FEC is active while board level
workaround for ERR006687 is not available
- A number patches to fix sparse warnings and spell errors
- A fix for TZIC FIQ translation from VIRQ to HWIRQ
- Support compatible of i.MX7 Solo SoC which has a subset of i.MX7 Dual

The i.MX6 Q/DL has an erratum (ERR006687) that prevents the FEC from
waking the CPUs when they are in wait(unclocked) state. As the hardware
workaround isn't applicable to all boards, disable the deeper idle state
when the workaround isn't present and the FEC is in use.
This allows to safely run a kernel with CPUidle enabled on all i.MX6
boards.

Using set_bit() to set a bit in an integer is not a good idea, since
the function expects an unsigned long as argument, which can be 64 bit
wide. Coverity reports this problem as
>>> CID 1364488: Memory - illegal accesses (INCOMPATIBLE_CAST)
>>> Pointer "&ret" points to an object whose effective type is "int"
>>> (32 bits, signed) but is dereferenced as a wider "unsigned
+long" (64 bits, unsigned). This may lead to memory corruption.
245 set_bit(1, (unsigned long *)&ret);
Just use BIT instead.

The IV output vectors should only be copied from the _complete operation
and not from the _process operation, i.e only from the operation that is
designed to copy the result of the request to the right location. This
copy is already done in the _complete operation, so this commit removes
the duplicated code in the _process op.

So far, the cache of the ahash requests was updated from the 'complete'
operation. This complete operation is called from mv_cesa_tdma_process
before the cleanup operation, which means that the content of req->src
can be read and copied when it is still mapped. This commit fixes the
issue by moving this cache update from mv_cesa_ahash_complete to
mv_cesa_ahash_req_cleanup, so the copy is done once the sglist is
unmapped.

The flag CRYPTO_TFM_REQ_MAY_BACKLOG is optional and can be set from the
user to put requests into the backlog queue when the main cryptographic
queue is full. Before calling mv_cesa_tdma_chain we must check the value
of the return status to be sure that the current request has been
correctly queued or added to the backlog.

So far in mv_cesa_ablkcipher_dma_req_init, if an error is thrown while
the tdma chain is built there is a memory leak. This issue exists
because the chain is assigned later at the end of the function, so the
cleanup function is called with the wrong version of the chain.

The LP8556 datasheet describes an EN/VDDIO input, which serves "both as
a chip enable and as a power supply reference for PWM, SDA, and SCL
inputs." The LP8556 that I'm testing doesn't respond properly if I try
to talk I2C to it too quickly after enabling VDDIO, and the LP8555
datasheet mentions a t_RESPONSE delay of up to 1 millisecond.
Support this EN/VDDIO by adding a regulator property to the binding;
enabling this regulator at probe time; and sleeping for 1 to 2ms, if the
EN/VDDIO regulator was provided.

The RPM has two sets of selectors (IPC bit fields): request and
acknowledge. Apparently, some models use 4*32 bit words for select
and some use 7*32 bit words for request, but all use 7*32 words
for acknowledge bits.
So apparently you can on the models with requests of 4*32 select
bits send 4*32 messages and get 7*32 different replies, so on ACK
interrupt, 7*32 bit words need to be read. This is how the vendor
code apparently works.

On some boards, like omap5-uevm the MCLK is gated by default and in order
to be able to use the High performance modes of twl6040 it need to be
enabled by SW.
Add support for handling the MCLK source clock via CCF.
At the same time lower the print priority of the notification that the 32K
clock is not provided and it is not going to be handled by the driver.
