In less than 10 ms, the temperature of soc will arise 10 degree. 250 ms
is too big for soc tempeture control. Setting 2.5 ms will speed up
temperature accessing speed but introduce no more cpu's computing overhead.
We set AUTO_PERIOD_TIME and TSADCV3_AUTO_PERIOD_HT_TIME the same value,
because normal temperature update speed is also our consern in IPA.

Big cores' power consumption is as much as 8 times of little cores'.
Eas tends to bring tasks to big cores to assure the performance, and
this will make the temperature of soc out of control. To resolve this
issue, we set the power request weight of both little cores and gpu is
10 times of big cores, when temperature control occurs. Meanwhile, we
decrease passive polling interval to make temperature control more
accurate.

Commit e22579713a ("ASoC: simple card: set cpu-dai sysclk
with mclk-fs") added sysclk / SND_SOC_CLOCK_OUT setting, that makes
asoc_simple_card_hw_params fail if the operation is not supported,
although the intention clearly was to ignore ENOTSUPP. Fix it.
The patch fixes audio playback on Kirkwood / OpenRD client,
where the following errors are seen:
asoc-simple-card sound: ASoC: machine hw_params failed: -524
alsa-lib: /alsa-lib-1.0.28/src/pcm/pcm_hw.c:327:(snd_pcm_hw_hw_params) SNDRV_PCM_IOCTL_HW_PARAMS failed (-524): Unknown error 524

It would be better to name OPP nodes as opp@<opp-hz> as that will ensure
that multiple DT nodes don't contain the same frequency. Of course we
expect the writer to name the node with its opp-hz frequency and not any
other frequency.
And that will let the compile error out if multiple nodes are using the
same opp-hz frequency.

stmmac_mdio_reset() has been updated to use msleep rather udelay
(as some PHY requires a one second delay there).
It called from stmmac_resume() within the spin_lock_irqsave block
atomic context triggering 'scheduling while atomic'.
The stmmac_priv lock usage is not fully documented, but it seems
to protect the access to the MAC registers / DMA structures rather
than the MDIO bus or the PHY (which have separate locking),
so we can push the spin_lock after the stmmac_mdio_reset call.

The dw_mmc driver stores the physical address of the MMIO registers
in a pointer, which requires the use of type casts, and is actually
broken if anyone ever has this device on a 32-bit SoC in registers
above 4GB. Gcc warns about this possibility when the driver is built
with ARM LPAE enabled:
mmc/host/dw_mmc.c: In function 'dw_mci_edmac_start_dma':
mmc/host/dw_mmc.c:702:17: warning: cast from pointer to integer of different size
cfg.dst_addr = (dma_addr_t)(host->phy_regs + fifo_offset);

mmc/host/dw_mmc-pltfm.c:63:19: warning: cast to pointer from integer of different size
host->phy_regs = (void *)(regs->start);
This changes the code to use resource_size_t, which gets rid of the
warning, the bug and the useless casts.

(cherry picked from commit 260b316436)
We must preserve the same order of how we acquire and release the lock for
genpd, as otherwise we may encounter deadlocks.
The power on phase of a genpd starts by acquiring its lock. Then it walks
the hierarchy of its parent domains to be able to power on these first, as
per design of genpd.
From a locking perspective this means the locks of the parents becomes
acquired after the lock of the subdomain.
Let's fix pm_genpd_add|remove_subdomain() to maintain the same order of
acquiring/releasing the genpd lock as being applied in the power on/off
sequence.

During genpd_poweron, genpd->lock is acquired recursively for each
parent (master) domain, which are separate objects. This confuses
lockdep, which considers every operation on genpd->lock as being done on
the same lock class. This leads to the following false positive warning:

We've unfortunately started seeing a situation where percpu interrupts
are partitioned in the system: one arbitrary set of CPUs has an
interrupt connected to a type of device, while another disjoint
set of CPUs has the same interrupt connected to another type of device.
This makes it impossible to have a device driver requesting this interrupt
using the current percpu-interrupt abstraction, as the same interrupt number
is now potentially claimed by at least two drivers, and we forbid interrupt
sharing on per-cpu interrupt.
A solution to this is to turn things upside down. Let's assume that our
system describes all the possible partitions for a given interrupt, and
give each of them a unique identifier. It is then possible to create
a namespace where the affinity identifier itself is a form of interrupt
number. At this point, it becomes easy to implement a set of partitions
as a cascaded irqchip, each affinity identifier being the HW irq.
This allows us to keep a number of nice properties:
- Each partition results in a separate percpu-interrupt (with a restrictied
affinity), which keeps drivers happy.
- Because the underlying interrupt is still per-cpu, the overhead of
the indirection can be kept pretty minimal.
- The core code can ignore most of that crap.
For that purpose, we implement a small library that deals with some of
the boilerplate code, relying on platform-specific drivers to provide
a description of the affinity sets and a set of callbacks.
