thermal: rockchip: optimize sensor auto accessing period

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.

UPSTREAM: ASoC: simple-card: don't fail if sysclk setting is not supported

Commit e22579713ae1 ("ASoC: simple card: set cpu-dai sysclk

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:

UPSTREAM: stmmac: do not sleep in atomic context for mdio_reset

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.

UPSTREAM: mmc: dw_mmc: use resource_size_t to store physical address

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: In function 'dw_mci_pltfm_register':
mmc/host/dw_mmc-pltfm.c:63:19: warning: cast to pointer from integer of different size
  host->phy_regs = (void *)(regs->start);

UPSTREAM: PM / Domains: Fix potential deadlock while adding/removing subdomains

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.

UPSTREAM: PM / domains: fix lockdep issue for all subdomains

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:

UPSTREAM: irqchip: Add per-cpu interrupt partitioning library

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.

UPSTREAM: genirq: Allow the affinity of a percpu interrupt to be set/retrieved

In order to prepare the genirq layer for the concept of partitionned
percpu interrupts, let's allow an affinity to be associated with
such an interrupt. We introduce:

- irq_set_percpu_devid_partition: flag an interrupt as a percpu-devid
interrupt, and associate it with an affinity
- irq_get_percpu_devid_partition: allow the affinity of that interrupt
to be retrieved.

This will allow a driver to discover which CPUs the per-cpu interrupt
can actually fire on.

UPSTREAM: irqdomain: Allow domain matching on irq_fwspec

When iterating over the irq domain list, we try to match a domain
either by calling a match() function or by comparing a number
of fields passed as parameters.

Both approaches are a bit restrictive:
- match() is DT specific and only takes a device node
- the fallback case only deals with the fwnode_handle

It would be useful if we had a per-domain function that would
actually perform the matching check on the whole of the
irq_fwspec structure. This would allow for a domain to triage
matching attempts that need to extend beyond the fwnode.

Let's introduce irq_find_matching_fwspec(), which takes a full
blown irq_fwspec structure, and call into a select() function
implemented by the irqdomain. irq_find_matching_fwnode() is
made a wrapper around irq_find_matching_fwspec in order to
preserve compatibility.

UPSTREAM: dt-bindings: arm, gic-v3: require that reserved cells are always 0

The arm,gic-v3 binding was written with good intentions and doesn't
enforce interrupt-cells to be 3, therefore making it easy to extend
the irq description in future if necessary:

  > Cells 4 and beyond are reserved for future use.

Unfortunately, this sentence is immediately followed up with:

  > When the 1st cell has a value of 0 or 1, cells 4 and beyond act as
  > padding, and may be ignored. It is recommended that padding cells
  > have a value of 0.

Consequently, any extensions to the PPI or SPI interrupt specifiers must
be able to work with random crap from legacy DTs, effectively
necessitating a new interrupt type in the first cell. Sigh.

This patch fixes the text so that additional, reserved cells are
required to be zero. This looks like a reasonable thing to require and
is already satisifed by the .dts files in-tree.

UPSTREAM: irqdomain: Allow domain lookup with DOMAIN_BUS_WIRED token

Let's take the (outlandish) example of an interrupt controller
capable of handling both wired interrupts and PCI MSIs.

With the current code, the PCI MSI domain is going to be tagged
with DOMAIN_BUS_PCI_MSI, and the wired domain with DOMAIN_BUS_ANY.

Things get hairy when we start looking up the domain for a wired
interrupt (typically when creating it based on some firmware
information - DT or ACPI).

In irq_create_fwspec_mapping(), we perform the lookup using
DOMAIN_BUS_ANY, which is actually used as a wildcard. This gives
us one chance out of two to end up with the wrong domain, and
we try to configure a wired interrupt with the MSI domain.
Everything grinds to a halt pretty quickly.

What we really need to do is to start looking for a domain that
would uniquely identify a wired interrupt domain, and only use
DOMAIN_BUS_ANY as a fallback.

In order to solve this, let's introduce a new DOMAIN_BUS_WIRED
token, which is going to be used exactly as described above.
Of course, this depends on the irqchip to setup the domain
bus_token, and nobody had to implement this so far.

Only so far.

FROMLIST: common: DMA-mapping: add DMA_ATTR_ALLOC_SINGLE_PAGES attribute

This patch adds the DMA_ATTR_ALLOC_SINGLE_PAGES attribute to the
DMA-mapping subsystem.

This attribute can be used as a hint to the DMA-mapping subsystem that
it's likely not worth it to try to allocate large pages behind the
scenes.  Large pages are likely to make an IOMMU TLB work more
efficiently but may not be worth it.  See the Documentation contained in
this patch for more details about this attribute and when to use it.

Note that the name of the hint (DMA_ATTR_ALLOC_SINGLE_PAGES) is loosely
based on the name MADV_NOHUGEPAGE.  Just as there is MADV_NOHUGEPAGE
vs. MADV_HUGEPAGE we could also add an "opposite" attribute to
DMA_ATTR_ALLOC_SINGLE_PAGES.  Without having the "opposite" attribute
the lack of DMA_ATTR_ALLOC_SINGLE_PAGES means "use your best judgement
about whether to use small pages or large pages".

CHROMIUM: vb2: Add a new "use_dma_bidirectional" queue flag.

When set to 1 for CAPTURE queues by the driver on calling vb2_queue_init(),
forces the buffers on the queue to be allocated/mapped with
DMA_BIDIRECTIONAL DMA direction flag, instead of DMA_FROM_DEVICE. This
allows the device not only to write to the buffers, but also read out from
them. This may be useful e.g. for codec hardware, which may be using
CAPTURE buffers as reference to decode other buffers.

This flag is ignored for OUTPUT queues, as we don't want to allow HW to
be able to write to OUTPUT buffers.

CHROMIUM: [media] rk3288-vpu: Workaround for encode after decode

On RK3288 there is an issue with certain hardware state being corrupted
while decoding certain streams, which affects encoding task run directly
after that decoding task. To reinitialize the state properly, a dummy
encoding of a single 64x64 pixels keyframe must be performed before the
real encoding is run.

This patch adds necessary workaround code to the driver, which makes it
execute an encoding task using dummy buffers with static parameters
manually selected for lowest performance overhead and to assure that
aforementioned hardware state is reinitialized.
