650ba21b13 sched_ext: Implement DSQ iterator
DSQs are very opaque in the consumption path. The BPF scheduler has no way
of knowing which tasks are being considered and which is picked. This patch
adds BPF DSQ iterator.

- Allows iterating tasks queued on a DSQ in the dispatch order or reverse
  from anywhere using bpf_for_each(scx_dsq) or calling the iterator kfuncs
  directly.

- Has ordering guarantee where only tasks which were already queued when the
  iteration started are visible and consumable during the iteration.

v5: - Add a comment to the naked list_empty(&dsq->list) test in
      consume_dispatch_q() to explain the reasoning behind the lockless test
      and by extension why nldsq_next_task() isn't used there.

    - scx_qmap changes separated into its own patch.

v4: - bpf_iter_scx_dsq_new() declaration in common.bpf.h was using the wrong
      type for the last argument (bool rev instead of u64 flags). Fix it.

v3: - Alexei pointed out that the iterator is too big to allocate on stack.
      Added a prep patch to reduce the size of the cursor. Now
      bpf_iter_scx_dsq is 48 bytes and bpf_iter_scx_dsq_kern is 40 bytes on
      64bit.

    - u32_before() comparison factored out.

v2: - scx_bpf_consume_task() is separated out into a separate patch.

    - DSQ seq and iter flags don't need to be u64. Use u32.

d4af01c373 sched_ext: Take out ->priq and ->flags from scx_dsq_node
struct scx_dsq_node contains two data structure nodes to link the containing
task to a DSQ and a flags field that is protected by the lock of the
associated DSQ. One reason why they are grouped into a struct is to use the
type independently as a cursor node when iterating tasks on a DSQ. However,
when iterating, the cursor only needs to be linked on the FIFO list and the
rb_node part ends up inflating the size of the iterator data structure
unnecessarily making it potentially too expensive to place it on stack.

Take ->priq and ->flags out of scx_dsq_node and put them in sched_ext_entity
as ->dsq_priq and ->dsq_flags, respectively. scx_dsq_node is renamed to
scx_dsq_list_node and the field names are renamed accordingly. This will
help implementing DSQ task iterator that can be allocated on stack.

No functional change intended.

dc12273fa3 PCI: of_property: Add interrupt-controller property in PCI device nodes
PCI devices and bridges DT nodes created during the PCI scan are created
with the interrupt-map property set to handle interrupts.

In order to set this interrupt-map property at a specific level, a
phandle to the parent interrupt controller is needed. On systems that
are not fully described by a device-tree, the parent interrupt
controller may be unavailable (i.e. not described by the device-tree).

As mentioned in the [1], avoiding the use of the interrupt-map property
and considering a PCI device as an interrupt controller itself avoid the
use of a parent interrupt phandle.

In that case, the PCI device itself as an interrupt controller is
responsible for routing the interrupts described in the device-tree
world (DT overlay) to the PCI interrupts.

Add the 'interrupt-controller' property in the PCI device DT node.

5e91cef944 Input: himax_hx83112b - add support for HX83100A
The HX83100A is a bit of an outlier in the Himax HX831xxx series of
touch controllers as it requires reading touch events through the AHB
interface of the MCU rather than providing a dedicated FIFO address like
the other chips do.
This patch implements the specific read function and introduces the
HX83100A chip with an appropriate i2c ID and DT compatible string.

The HX83100A doesn't have a straightforward way to do chip
identification, which is why it is not implemented in this patch.

however EBUSY will simply output the generic message:

    Error xiic_start_xfer

which is not really helpful.

This commit adds a new error message when a busy condition is detected
and also removes the generic message since it does not provide any
relevant information to the user.

d5adffc46f dt-bindings: i2c: nxp,lpc1788-i2c: convert to dt schema
Convert the NXP I2C controller for LPC2xxx/178x/18xx/43xx
to newer DT schema. Created DT schema based on the .txt file
which had `compatible`, `reg`, `interrupts`, `clocks`,
`#address-cells` and `#size-cells` as required properties.

Additional changes to the original .txt binding
- added maintainer from the MAINTAINERS file.
- added resets property required by the corresponding DTS files.

2362c73002 dt-bindings: i2c: adjust indentation in DTS example to coding style
Bindings coding style expects 2- or 4-space indentation in the DTS
example.  Correct files having something odd (6- or 8-space) to 4-space
while re-ordering few properties according to DTS coding style (the
first property should be compatible, then reg/ranges).  No functional
impact.

require them, because I2C controller could be enabled without any

7da7fd7e66 i2c: omap: wakeup the controller during suspend() callback
A device may need the controller up during suspend_noirq() or
resume_noirq().
But if the controller is autosuspended, there is no way to wakeup it during
suspend_noirq() or resume_noirq() because runtime pm is disabled at this
time.

The suspend() callback wakes up the controller, so it is available until
its suspend_noirq() callback (pm_runtime_force_suspend()).
During the resume, it's restored by resume_noirq() callback
(pm_runtime_force_resume()). Then resume() callback enables autosuspend.

So the controller is up during a little time slot in suspend and resume
sequences even if it's not used.

The usage of pm_ptr() and these more recent macros allows the compiler to
see and drop the dead code.
The unnecessary '__maybe_unused' annotations on PM functions can be

86588139b8 Documentation: CXL Maturity Map
Provide a survey of the work-in-progress maturity (implementation
status) of various aspects of the CXL subsystem.

Clarify that in addition to ongoing upkeep relative to specification
updates, there are some long running themes in the driver that respond
to the discovery of new corner cases (bugs) and new use cases (feature
extensions).

The primary audience is distribution maintainers, but it also serves as
a guide for kernel developers to understand what aspects of the CXL
subsystem need more help. It is a landing page to document ongoing
progress, and a guide to discern exposure to work-in-progress features.
