On systems booting with a device tree, every struct device is associated
with a struct device_node, that provides its DT firmware representation.
The device node can be used in generic kernel contexts (eg IRQ
translation, IOMMU streamid mapping), to retrieve the properties
associated with the device and carry out kernel operations accordingly.
Owing to the 1:1 relationship between the device and its device_node,
the device_node can also be used as a look-up token for the device (eg
looking up a device through its device_node), to retrieve the device in
kernel paths where the device_node is available.
On systems booting with ACPI, the same abstraction provided by
the device_node is required to provide look-up functionality.
The struct acpi_device, that represents firmware objects in the
ACPI namespace already includes a struct fwnode_handle of
type FWNODE_ACPI as their member; the same abstraction is missing
though for devices that are instantiated out of static ACPI tables
entries (eg ARM SMMU devices).
Add a new fwnode_handle type to associate devices created out
of static ACPI table entries to the respective firmware components
and create a simple ACPI core layer interface to dynamically allocate
and free the corresponding firmware nodes so that kernel subsystems
can use it to instantiate the nodes and associate them with the
respective devices.

The cec_allocate_adapter function doesn't need the parent device, only the
cec_register_adapter function needs it.
Drop the cec_devnode parent field, since devnode.dev.parent can be used
instead.
This change makes the framework consistent with other frameworks where the
parent device is not used until the device is registered.

Idle injection drivers such as Intel powerclamp and ACPI PAD drivers use
realtime tasks to take control of CPU then inject idle. There are two
issues with this approach:
1. Low efficiency: injected idle task is treated as busy so sched ticks
do not stop during injected idle period, the result of these
unwanted wakeups can be ~20% loss in power savings.
2. Idle accounting: injected idle time is presented to user as busy.
This patch addresses the issues by introducing a new PF_IDLE flag which
allows any given task to be treated as idle task while the flag is set.
Therefore, idle injection tasks can run through the normal flow of NOHZ
idle enter/exit to get the correct accounting as well as tick stop when
possible.
The implication is that idle task is then no longer limited to PID == 0.

When idle injection is used to cap power, we need to override the
governor's choice of idle states.
For this reason, make it possible the deepest idle state selection to
be enforced by setting a flag on a given CPU to achieve the maximum
potential power draw reduction.

Rework the IRQ handler by using HW IRQ number and status bit.
Each HW IRQ number is matched with TPS65217 register layout[*].
(USB IRQ number is 0, AC is 1, Push button is 2)
When an interrupt is enabled, mask bit should be cleared (unmasked).
If an interrupt is disabled, then mask bit should be set (masked).
This mask value is updated into the TPS65217 register in irq_sync_unlock().
Mask bit and interrupt status bit can be handled with HW IRQ number.
Eventually, additional IRQ data, 'tps65217_irqs[]' and the function,
'irq_to_tps65217_irq()' are not necessary.

The AXP806 supports either master/standalone or slave mode.
Slave mode allows sharing the serial bus, even with multiple
AXP806 which all have the same hardware address.
This is done with extra "serial interface address extension",
or AXP806_BUS_ADDR_EXT, and "register address extension", or
AXP806_REG_ADDR_EXT, registers. The former is read-only, with
1 bit customizable at the factory, and 1 bit depending on the
state of an external pin. The latter is writable. Only when
the these device addressing bits (in the upper 4 bits of the
registers) match, will the device respond to operations on
its other registers.
Add these 2 registers to the regmap so we can access them.

I've had it with this code now.
The packed command support is a complex hurdle in the MMC/SD block
layer, around 500+ lines of code which was introduced in 2013 in
commit ce39f9d17c14 ("mmc: support packed write command for eMMC4.5
devices")
commit abd9ac144947 ("mmc: add packed command feature of eMMC4.5")
...and since then it has been rotting. The original author of the
code has disappeared from the community and the mail address is
bouncing.
For the code to be exercised the host must flag that it supports
packed commands, so in mmc_blk_prep_packed_list() which is called for
every single request, the following construction appears:
u8 max_packed_rw = 0;
if ((rq_data_dir(cur) == WRITE) &&
mmc_host_packed_wr(card->host))
max_packed_rw = card->ext_csd.max_packed_writes;
if (max_packed_rw == 0)
goto no_packed;
This has the following logical deductions:
- Only WRITE commands can really be packed, so the solution is
only half-done: we support packed WRITE but not packed READ.
The packed command support has not been finalized by supporting
reads in three years!
- mmc_host_packed_wr() is just a static inline that checks
host->caps2 & MMC_CAP2_PACKED_WR. The problem with this is
that NO upstream host sets this capability flag! No driver
in the kernel is using it, and we can't test it. Packed
command may be supported in out-of-tree code, but I doubt
it. I doubt that the code is even working anymore due to
other refactorings in the MMC block layer, who would
notice if patches affecting it broke packed commands?
No one.
- There is no Device Tree binding or code to mark a host as
supporting packed read or write commands, just this flag
in caps2, so for sure there are not any DT systems using
it either.
It has other problems as well: mmc_blk_prep_packed_list() is
speculatively picking requests out of the request queue with
blk_fetch_request() making the MMC/SD stack harder to convert
to the multiqueue block layer. By this we get rid of an
obstacle.
The way I see it this is just cruft littering the MMC/SD
stack.

The void (*pre_req) callback in the struct mmc_host_ops vtable
is passing an argument "is_first_req" indicating whether this is
the first request or not.
None of the in-kernel users use this parameter: instead, since
they all just do variants of dma_map* they use the DMA cookie
to indicate whether a pre* callback has already been done for
a request when they decide how to handle it.
Delete the parameter from the callback and all users, as it is
just pointless cruft.

There were several instances of code using the
enum mmc_blk_status by arbitrarily converting it to an int and
throwing it around to different functions. This makes the code
hard to understand to may give rise to strange errors.
Especially the function prototype mmc_start_req() had to be
modified to take a pointer to an enum mmc_blk_status and the
function pointer .err_check() inside struct mmc_async_req
needed to return an enum mmc_blk_status.
In every case: instead of assigning the block layer error code
to an int, use the enum, also change the signature of all
functions actually passing this enum to use the enum.
To make it possible to use the enum everywhere applicable, move
it to <linux/mmc/core.h> so that all code actually using it can
also see it.
An interesting case was encountered in the MMC test code which
did not return a enum mmc_blk_status at all in the .err_check
function supposed to check whether asynchronous requests worked
or not: instead it returned a normal -ERROR or even the test
frameworks internal error codes.
The test code would also pass on enum mmc_blk_status codes as
error codes inside the test code instead of converting them
to the local RESULT_* codes.
I have tried to fix all instances properly and run some tests
on the result.

The purpose of HID_QUIRK_MULTI_INPUT is to have an input device per
report id. This is useful when the HID device presents several HID
collections of different device types.
The current implementation of hid-input creates one input node per id per
type (input or output). This is problematic for the LEDs of a keyboard as
they are often set through an output report. The current code creates
one input node with all the keyboard keys, and one other with only the
LEDs.
To solve this, we use a two-passes way:
- first, we initialize all input nodes and associate one per report id
- then, we register all the input nodes

The kvm module has the parameters halt_poll_ns, halt_poll_ns_grow, and
halt_poll_ns_shrink. Halt polling was recently added to the powerpc kvm-hv
module and these parameters were essentially duplicated for that. There is
no benefit to this duplication and it can lead to confusion when trying to
tune halt polling.
Thus move the definition of these variables to kvm_host.h and export them.
This will allow the kvm-hv module to use the same module parameters by
accessing these variables, which will be implemented in the next patch,
meaning that they will no longer be duplicated.

Pull IOMMU fixes from David Woodhouse:
"Two minor fixes.
The first fixes the assignment of SR-IOV virtual functions to the

iommu/vt-d: Fix PASID table allocation
iommu/vt-d: Fix IOMMU lookup for SR-IOV Virtual Functions

udplite conflict is resolved by taking what 'net-next' did
which removed the backlog receive method assignment, since
it is no longer necessary.
Two entries were added to the non-priv ethtool operations
switch statement, one in 'net' and one in 'net-next, so
simple overlapping changes.
