1.Using the FCLK DPM table to set the MCLK for DPM states consist of
three entities:
FCLK
UCLK
MEMCLK
All these three clk change together, MEMCLK from FCLK, so use the fclk
frequency.
2.we should show the current working clock freqency from clock table metric

If the backing device for a loop device is itself a block device,
then mirror the "write zeroes" capabilities of the underlying
block device into the loop device. Copy this capability into both
max_write_zeroes_sectors and max_discard_sectors of the loop device.
The reason for this is that REQ_OP_DISCARD on a loop device translates
into blkdev_issue_zeroout(), rather than blkdev_issue_discard(). This
presents a consistent interface for loop devices (that discarded data
is zeroed), regardless of the backing device type of the loop device.
There should be no behavior change for loop devices backed by regular
files.
This change fixes blktest block/003, and removes an extraneous
error print in block/013 when testing on a loop device backed
by a block device that does not support discard.

This driver allows pwms to be requested as gpios via gpiolib. Obviously,
it should not be allowed to request a GPIO when its corresponding PWM is
already requested (and vice versa). So it requires some exclusion code.
Given that the PWMm and GPIO cores are not synchronized with respect to
each other, this exclusion code will also require proper
synchronization.
Such a mechanism was in place, but was inadvertently removed by Uwe's
clean-up in commit e926b12c611c ("pwm: Clear chip_data in pwm_put()").
Upon revisiting the synchronization mechanism, we found that
theoretically, it could allow two threads to successfully request
conflicting PWMs/GPIOs.
Replace with a bitmap which tracks PWMs in-use, plus a mutex. As long as
PWM and GPIO's respective request/free functions modify the in-use
bitmap while holding the mutex, proper synchronization will be
guaranteed.

It is wrong to block the user thread in the next poll when OA data is
already available which could not fit in the user buffer provided in
the previous read. In several cases the exact user buffer size is not
known. Blocking user space in poll can lead to data loss when the
buffer size used is smaller than the available data.
This change fixes this issue and allows user space to read all OA data
even when using a buffer size smaller than the available data using
multiple non-blocking reads rather than staying blocked in poll till
the next timer interrupt.

Add support for the Kendryte K210 RISC-V SoC. For now, this support
only provides a simple sysctl driver allowing to setup the CPU and
uart clock. This support is enabled through the new Kconfig option
SOC_KENDRYTE and defines the config option CONFIG_K210_SYSCTL
to enable the K210 SoC sysctl driver compilation.
The sysctl driver also registers an early SoC initialization function
allowing enabling the general purpose use of the 2MB of SRAM normally
reserved for the SoC AI engine. This initialization function is
automatically called before the dt early initialization using the flat
dt root node compatible property matching the value "kendryte,k210".

the atomic state all the way down.
The alternative would be yet another encoder hook which we'll
have to call after all the normal modeset stuff is done. Not
really a fan of yet another hook just for this.
Note that during readout state sanitation we are now going
to pass NULL as the atomic state since we don't have one.

Transcoder port sync was introduced to the hardware in BDW. We
can trivially enable it for SKL+ since the same codepaths are
already used for ICL+ port sync. The only difference is the actual
location of the bits we need to poke.
We leave BDW out (at least for now) since it uses different modeset
paths that haven't been adapted for port sync, and IIRC using the
feature would involve some extra workarounds we've not implemented.
Pre-BDW hardware does not support port sync so we'd have to tweak
the modeset sequence to start the pipes as close together as possible
and hope for the best. So far no one has seriously tried to implement
that.

This reverts commit effd58c95f277744f75d6e08819ac859dbcbd351.
blk_queue_split() is causing excessive IO splitting -- because
blk_max_size_offset() depends on 'chunk_sectors' limit being set and
if it isn't (as is the case for DM targets!) it falls back to
splitting on a 'max_sectors' boundary regardless of offset.
"Fix" this by reverting back to _not_ using blk_queue_split() in
dm_process_bio() for normal IO (reads and writes). Long-term fix is
still TBD but it should focus on training blk_max_size_offset() to
call into a DM provided hook (to call DM's max_io_len()).
Test results from simple misaligned IO test on 4-way dm-striped device
with chunksize of 128K and stripesize of 512K:

Add a tiny per-engine request mempool so that we should always have a
request available for powermanagement allocations from tricky
contexts. This reserve is expected to be only used for kernel
contexts when barriers must be emitted [almost] without fail.
The main consumer for this reserved request is expected to be engine-pm,
for which we know that there will always be at least the previous pm
request that we can reuse under mempressure (so there should always be
a spare request for engine_park()).
This is an alternative to using a comparatively bulky mempool, which
requires custom handling for both our reserved allocation requirement
and to protect our TYPESAFE_BY_RCU slab cache. The advantage of mempool
would be that it would allow us to keep a larger per-engine request
pool. However, converting over to mempool is straightforward should the
need arise.

When we are using a system with big.LITTLE HMP
configuration, we need to use EAS to schedule the
system.
As can be seen from kernel/sched/topology.c:
"EAS can be used on a root domain if it meets all the following conditions:
1. an Energy Model (EM) is available;
2. the SD_ASYM_CPUCAPACITY flag is set in the sched_domain hierarchy.
3. no SMT is detected.
4. the EM complexity is low enough to keep scheduling overheads low;
5. schedutil is driving the frequency of all CPUs of the rd;"
This means that at the very least, schedutil needs to be
available as a scheduling policy for EAS to work on these
systems. Make this explicit by defaulting to the schedutil
governor if BIG_LITTLE is selected.
Currently users of the TC2 board (like me) has to figure these
dependencies out themselves and it is not helpful.

Currently in the case where eq->src != req->ds, the allocation of
ptr is kfree'd at the end of the code block. However later on in
the case where enc is not null any of the error return paths that
return via the error handling return path end up performing an
erroneous second kfree of ptr.
Fix this by adding an error exit label error_free and only jump to
this when ptr needs kfree'ing thus avoiding the double free issue.

zero_page_range() dax operation is mandatory for dax devices. Right now
that check happens in dax_zero_page_range() function. Dan thinks that's
too late and its better to do the check earlier in alloc_dax().
I also modified alloc_dax() to return pointer with error code in it in
case of failure. Right now it returns NULL and caller assumes failure
happened due to -ENOMEM. But with this ->zero_page_range() check, I
need to return -EINVAL instead.

Add a dax operation zero_page_range, to zero a page. This will also clear any
known poison in the page being zeroed.
As of now, zeroing of one page is allowed in a single call. There
are no callers which are trying to zero more than a page in a single call.
Once we grow the callers which zero more than a page in single call, we
can add that support. Primary reason for not doing that yet is that this
will add little complexity in dm implementation where a range might be
spanning multiple underlying targets and one will have to split the range
into multiple sub ranges and call zero_page_range() on individual targets.
