It is preferred that drivers use platform_get_irq() instead of
irq_of_parse_and_map(), so replace.

platform_get_resource(pdev, IORESOURCE_IRQ, ..) relies on static
allocation of IRQ resources in DT core code, this causes an issue when
using hierarchical interrupt domains using "interrupts" property in
the node as this bypasses the hierarchical setup and messes up the irq
chaining.
In preparation for removal of static setup of IRQ resource from DT
core code use platform_get_irq().

Add a driver for the keyboard, touchpad and USB port of
the keyboard dock for the Asus TF103C 2-in-1 tablet.
This keyboard dock has its own I2C attached embedded controller
and the keyboard and touchpad are also connected over I2C,
instead of using the usual USB connection. This means that the
keyboard dock requires this special driver to function.

The whitelabel (sold as various brands) TM800A550L tablets's DSDT contains
a whole bunch of bogus ACPI I2C devices and the ACPI node describing
the touchscreen is bad (the IRQ is missing). Enumeration of these is
skipped through the acpi_quirk_skip_i2c_client_enumeration().
Add support for manually instantiating the (now) missing I2C devices by
adding the necessary device info to the x86-android-tablets module,
including instantiating an actually working i2c-client for
the touchscreen.

Since the x86-android-tablets code does all it work from module_init() it
cannot use -EPROBE_DEFER to wait for e.g. interrupt providing GPIO-chips
or PMIC-cells to show up.
To make sure things will still work when some necessary resource providers
are build as module allow the per board info to specify a list of modules
to pre-load before instantiating the I2C clients.

Add support for instantiating platform-devs, note this also makes some
small changes to the i2c_client instantiating code to make the 2 flows
identical.
Specifically for the pdevs flow pdev_count must only be set after
allocating the pdevs array, to avoid a NULL ptr deref in
x86_android_tablet_cleanup() and the i2c_clients flow is updated

The Crystal Cove PMIC has a pin which can be used to connect the IRQ of
an external charger IC. On some boards this is used so we need a way to
look this up.
Note that the Intel PMICs have 2 levels of interrupts and thus
2 levels of IRQ domains all tied to a single fwnode.
Level 1 is the irqchip which demultiplexes the actual PMIC interrupt into
interrupts for the various MFD cells. Level 2 are the irqchips used in the
cell drivers which themselves export IRQs, such as the crystal_cove_gpio
driver, which de-multiplexes the level 2 interrupts for the GPIOs into
individual per GPIO IRQs.
The crystal_cove_charger driver registers an irqchip with a single IRQ for
the charger driver to consume. Note the MFD cell IRQ cannot be consumed
directly because the level 2 interrupts must be explicitly acked.
To allow finding the right IRQ domain when looking up the IRQ for
the charger, the crystal_cove_charger driver sets a DOMAIN_BUS_WIRED token
on its IRQ domain.
Add support for looking up the IRQ from the crystal_cove_charger driver.

The Glavey TM800A550L tablet is a tablet which ships with Android as
factory OS. As such it has the typical broken DSDT which x86 Android
tablets tend to have.
Specifically the touchscreen ACPI device node is missing the IRQ for
the touchscreen. So far users were expected to fix this with a DSDT
overlay, but support for the TM800A550L has been added to the new
x86-android-modules kernel-module and that will now automatically
instantiate a proper i2c-client with the IRQ set for the touchscreen,
including the necessary device-properties for the firmware loading.
This means that the touchscreen_dmi entry for the TM800A550L is
no longer necessary (and it no longer matches either since the
touchscreen is no longer enumerated through ACPI), remove it.

(CWI529) tablet
The firmware distributed as part of the Windows and Android drivers uses
significantly different min and max values for the x- and y-axis,
compared to the EFI's embedded touchscreen firmware.
The difference is large enough that e.g. typing on an onscreen keyboard
results in the wrong "keys" getting pressed.
Adjust the values to match those of the firmware distributed with the
Windows and Android drivers (which is necessary for pen support) and
put the EFI-fw version's min/max values in the new "silead,efi-fw-min-max"
property. The silead driver will use these when it is using the
EFI embedded firmware, so as to not regress functionality in that case.

Driver for the external-charger IRQ pass-through function of the
Intel Bay Trail Crystal Cove PMIC.
Note this is NOT a power_supply class driver, it just deals with IRQ
pass-through, this requires this separate driver because the PMIC's
level 2 interrupt for this must be explicitly acked.
This new driver gets enabled by the existing X86_ANDROID_TABLETS Kconfig
option because the x86-android-tablets module is the only consumer of the
exported external-charger IRQ.

Depending on BIOS configuration IOSM driver exchanges
protocol required for putting device into D3L2 or D3L1.2.
ipc_pcie_suspend_s2idle() is implemented to put device to D3L1.2.
This patch forces PCI core know this device should stay at D0.
- pci_save_state()is expensive since it does a lot of slow PCI
config reads.
The reported issue is not observed on x86 platform. The supurios
wake on AMD platform needs to be futher debugged with orignal patch
submitter [1]. Also the impact of adding pci_save_state() needs to be
assessed by testing it on other platforms.
This reverts commit f4dd5174e273("net: wwan: iosm: Keep device

In the absence of this validation, if the user requests to
configure queues more than the enabled queues, it results in
sending the requested number of queues to the kernel stack
(due to the asynchronous nature of VF response), in which
case the stack might pick a queue to transmit that is not
enabled and result in Tx hang. Fix this bug by
limiting the total number of queues allocated for VF to
active queues of VF.

PCC OpRegion provides a mechanism to communicate with the platform
directly from the AML. PCCT provides the list of PCC channel available
in the platform, a subset or all of them can be used in PCC Opregion.
This patch registers the PCC OpRegion handler before ACPI tables are
loaded. This relies on the special context data passed to identify and
set up the PCC channel before the OpRegion handler is executed for the
first time.
Typical PCC Opregion declaration looks like this:
OperationRegion (PFRM, PCC, 2, 0x74)
Field (PFRM, ByteAcc, NoLock, Preserve)
{
SIGN, 32,
FLGS, 32,
LEN, 32,
CMD, 32,
DATA, 800
}
It contains four named double words followed by 100 bytes of buffer
names DATA.
ASL can fill out the buffer something like:
/* Create global or local buffer */
Name (BUFF, Buffer (0x0C){})
/* Create double word fields over the buffer */
CreateDWordField (BUFF, 0x0, WD0)
CreateDWordField (BUFF, 0x04, WD1)
CreateDWordField (BUFF, 0x08, WD2)
/* Fill the named fields */
WD0 = 0x50434300
SIGN = BUFF
WD0 = 1
FLGS = BUFF
WD0 = 0x10
LEN = BUFF
/* Fill the payload in the DATA buffer */
WD0 = 0
WD1 = 0x08
WD2 = 0
DATA = BUFF
/* Write to CMD field to trigger handler */
WD0 = 0x4404
CMD = BUFF
This buffer is received by acpi_pcc_opregion_space_handler. This
handler will fetch the complete buffer via internal_pcc_buffer.
The setup handler will receive the special PCC context data which will
contain the PCC channel index which used to set up the channel. The
buffer pointer and length is saved in region context which is then used
in the handler.

Get rid of old erofs_get_meta_page() within zmap operations by
using on-stack meta buffers in order to prepare subpage and folio
features.
Finally, erofs_get_meta_page() is useless. Get rid of it!

In order to support subpage and folio for all uncompressed files,
introduce meta buffer descriptors, which can be effectively stored
on stack, in place of meta page operations.
This converts the uncompressed data path to meta buffers.

The current EPB "normal" is defined as 6 and set whenever power-up EPB
value is 0. This setting resulted in the desired out of box power and
performance for several CPU generations. But this value is not suitable
for AlderLake mobile CPUs, as this resulted in higher uncore power.
Since EPB is model specific, this is not unreasonable to have different
behavior.
Allow a capability where "normal" EPB can be redefined. For AlderLake
mobile CPUs this desired normal value is 7.

Commit e2012600810c ("arm64: perf: Add userspace counter access disable
switch") introduced a new 'perf_user_access' sysctl file to enable and
disable direct userspace access to the PMU counters. Sadly, Geert
reports that on his big.LITTLE SoC ('Renesas Salvator-XS w/ R-Car H3'),
the file is created for each PMU type probed, resulting in a splat
during boot:

Introduce a state variable to track creation of the sysctl file and
ensure that it is only created once.

When a mesh link is in blocked state, it is very useful to still allow
auth requests from the peer to re-establish it.
When a remote node is power cycled, the peer state can easily end up
in blocked state if multiple auth attempts are performed. Since this
can lead to several minutes of downtime, we should accept auth attempts
of the peer after it has come back.

ieee80211_iterate_active_interfaces() and
ieee80211_iterate_active_interfaces_atomic() already exist, where the
former allows the iterator function to sleep. Add
ieee80211_iterate_stations() which is similar to
ieee80211_iterate_stations_atomic() but allows the iterator to sleep.
This is needed for adding SDIO support to the rtw88 driver. Some
interators there are reading or writing registers. With the SDIO ops
(sdio_readb, sdio_writeb and friends) this means that the iterator
function may sleep.
