Currently the function that does this takes a struct file_lock, but
__locks_wake_up_blocks() deals with both locks and leases. Currently
this works because both file_lock and file_lease have the file_lock_core
at the beginning of the struct, but it's fragile to rely on that.
Add a new locks_wake_up_waiter() function and call that from
__locks_wake_up_blocks().

Add device tree for the Luckfox Omni3576 Carrier Board with Core3576
Module, powered by the Rockchip RK3576 SoC with four Cortex-A72 cores,
four Cortex-A53 cores, and a Mali-G52 MC3 GPU. This initial
implementation enables essential functionality for booting Linux and
basic connectivity.
Supported and tested features:
- UART for serial console
- SD card for storage
- PCIe with NVMe SSD (detected, mounted, and fully functional)
- USB 2.0 host ports
- RK806 PMIC for power management
- RTC with timekeeping and wake-up
- GPIO-controlled LED with heartbeat trigger
- eMMC (enabled, not populated on tested board)
The device tree provides a foundation for further peripheral support, such
as WiFi, MIPI-DSI, HDMI, and Ethernet, in future updates.
Tested on Linux 6.15-rc4
Based on the Luckfox SDK, which derives from Rockchip’s SDK examples, with
relevant changes to align with upstream Linux.

The RK3588 GPU power domain cannot be activated unless the external
power regulator is already on. When GPU support was added to this DT,
we had no way to represent this requirement, so `regulator-always-on`
was added to the `vdd_gpu_s0` regulator in order to ensure stability.
A later patch series (see "Fixes:" commit) resolved this shortcoming,
but that commit left the workaround -- and rendered the comment above
it no longer correct.
Remove the workaround to allow the GPU power regulator to power off, now
that the DT includes the necessary information to power it back on
correctly.

The RZ/{G2L,V2L,G3S} CPG versions support a feature called MSTOP. Each
module has one or more MSTOP bits associated with it, and these bits
need to be configured along with the module clocks. Setting the MSTOP
bits switches the module between normal and standby states.
Previously, MSTOP support was abstracted through power domains (struct
generic_pm_domain::{power_on, power_off} APIs). With this abstraction,
the order of setting the MSTOP and CLKON bits was as follows:
Previous Order:
A/ Switching to Normal State (e.g., during probe):
1/ Clear module MSTOP bit
2/ Set module CLKON bit
B/ Switching to Standby State (e.g., during remove):
1/ Clear CLKON bit
2/ Set MSTOP bit
However, in some cases (when the clock is disabled through devres), the
order may have been (due to the issue described in link section):
1/ Set MSTOP bit
2/ Clear CLKON bit
Recently, the hardware team has suggested that the correct order to set
the MSTOP and CLKON bits is:
Updated Order:
A/ Switching to Normal State (e.g., during probe):
1/ Set CLKON bit
2/ Clear MSTOP bit
B/ Switching to Standby State (e.g., during remove):
1/ Set MSTOP bit
2/ Clear CLKON bit
To prevent future issues due to incorrect ordering, the MSTOP setup has
now been implemented in rzg2l_mod_clock_endisable(), ensuring compliance
with the sequence suggested in Figure 41.5: Module Standby Mode
Procedure from the RZ/G3S HW manual, Rev1.10.
Additionally, since multiple clocks of a single module may be mapped to
a single MSTOP bit, MSTOP setup is reference-counted.
Furthermore, as all modules start in the normal state after reset, if
the module clocks are disabled, the module state is switched to standby.
This prevents keeping the module in an invalid state, as recommended by
the hardware team.

Instead of adding more parameters, move the needed parameters to a public

Instead moving clks to this structure, which would have implied to add
an allocation (and cleanup) for it, keep the way the allocation is done
and just have a copy of the pointer in the public structure.

The mailbox framework has a single inflight request at a time. If
a request is sent while another is still active, it will be queued
to the mailbox core ring buffer.
ACPM protocol did not serialize the calls to the mailbox subsystem so we
could start the timeout ticks in parallel for multiple requests, while
just one was being inflight.
Consider a hypothetical case where the xfer timeout is 100ms and an ACPM
transaction takes 90ms:
| 0ms: Message #0 is queued in mailbox layer and sent out, then sits
| at acpm_dequeue_by_polling() with a timeout of 100ms
| 1ms: Message #1 is queued in mailbox layer but not sent out yet.
| Since send_message() doesn't block, it also sits at
| acpm_dequeue_by_polling() with a timeout of 100ms
| ...
| 90ms: Message #0 is completed, txdone is called and message #1 is sent
| 101ms: Message #1 times out since the count started at 1ms. Even though
| it has only been inflight for 11ms.
Fix the problem by moving mbox_send_message() and mbox_client_txdone()
immediately after the message has been written to the TX queue and while
still keeping the ACPM TX queue lock. We thus tie together the TX write
with the doorbell ring and mark the TX as done after the doorbell has
been rung. This guarantees that the doorbell has been rang before
starting the timeout ticks. We should also see some performance
improvement as we no longer wait to receive a response before ringing
the doorbell for the next request, so the ACPM firmware shall be able to
drain faster the TX queue. Another benefit is that requests are no
longer able to ring the doorbell one for the other, so it eases
debugging. Finally, the mailbox software queue will always contain a
single doorbell request due to the serialization done at the ACPM TX
queue level. Protocols like ACPM, that handle their own hardware queues
need a passthrough mailbox API, where they are able to just ring the
doorbell or flip a bit directly into the mailbox controller. The mailbox
software queue mechanism, the locking done into the mailbox core is not
really needed, so hopefully this lays the foundation for a passthrough
mailbox API.

Since the introduction of alloc_candev_mqs() and friends, there is no
longer a need to allocate a generic network device and perform explicit
CAN-specific setup. Remove the code showing this setup, and document
alloc_candev_mqs() instead.

Vincent Mailhol <mailhol.vincent@wanadoo.fr> says:
An RFC was sent last weekend to kick-off the discussion of the
introduction of CAN XL [1]. While the series received some positive
feedback, it is far from completion. Some work is still needed to:
- adjust the nesting of the IFLA_CAN_XL_DATA_BITTIMING_CONST in the
netlink interface
- add the CAN XL PWM configuration
and this TODO list may grow if more feedback is received.
Regardless of this, the RFC started with a tree wide refactor followed
by a set of trivial patches to do some clean-up and some renaming in
preparation of the introduction of CAN XL.
This series just contains those preparation patch which were cherry
picked from the RFC and rebased on of top of linux-can-next/main:
- the first patch is purely cosmetic and fixes a trivial tabulation
mistake.
- the last three patches do some renaming: both the CAN FD and the
CAN XL have databittiming parameters. In order not to get confused
once CAN XL will be introduced, many symbols are modified to
explicitly add CAN FD in their names.
The goal is to have those merged first to remove some overhead from
the netlink CAN XL main series before tacking care of the other
comments.

Add initial ostd setting for mt8186. All the settings come from DE.
These settings help adjust Multimedia HW's bandwidth limits to achieve
a balanced bandwidth requirement. Without this, the VENC HW works
abnormal while stress testing.

Use syscon_regmap_lookup_by_phandle_args() which is a wrapper over
syscon_regmap_lookup_by_phandle() combined with getting the syscon
argument. Except simpler code this annotates within one line that given
phandle has arguments, so grepping for code would be easier.
