Follow-on from the companion dt-bindings change ("dt-bindings: gpu: img:
More explicit compatible strings"), deprecating "img,img-axe" in favour of
the more explicit combination of "img,img-rogue" and "img,img-axe-1-16m".
Since all relevant details are interrogated from the device at runtime,
we can match on the generic "img,img-rogue" and avoid adding more entries
with NULL data members (barring hardware quirks).

The first compatible strings added for the AXE-1-16M are not sufficient to
accurately describe all the IMG Rogue GPUs. The current "img,img-axe"
string refers to the entire family of Series AXE GPUs, but this is
primarily a marketing term and does not denote a level of hardware
similarity any greater than just "Rogue".
The more specific "img,img-axe-1-16m" string refers to individual AXE-1-16M
GPU. For example, unlike the rest of the Series AXE GPUs, the AXE-1-16M
only uses a single power domain.
The situation is actually slightly worse than described in the first
paragraph, since many "series" (such as Series BXS found in the TI AM68
among others and added later in this series) contain cores with both Rogue
and Volcanic architectures.
Besides attempting to move away from vague groupings defined only
by marketing terms, we want to draw a line between properties inherent to
the IP core and choices made by the silicon vendor at integration time.
For instance, the number of power domains is a property of the IP core,
whereas the decision to use one or multiple clocks is a vendor one.
In the original compatible strings, we must use "ti,am62-gpu" to constrain
both of these properties since the number of power domains cannot be fixed
for "img,img-axe".
Work is currently underway to add support for volcanic-based Imagination
GPUs, for which bindings will be added in "img,powervr-volcanic.yaml".
As alluded to previously, the split between rogue and volcanic cores is
non-obvious at times, so add a generic top-level "img,img-rogue" compatible
string here to allow for simpler differentiation in devicetrees without
referring back to the bindings.
The currently supported GPU (AXE-1-16M) only requires a single power
domain. Subsequent patches will add support for BXS-4-64 MC1, which has
two power domains. Add infrastructure now to allow for this.
Also allow the dma-coherent property to be added to IMG Rogue GPUs, which
are DMA devices. The decision for coherency is made at integration time and
this property should be applied wherever it accurately describes the
vendor integration.
Note that the new required properties for power domains are conditional on
the new base compatible string to avoid an ABI break.

this kernel notification separately.
This patch adds the concept of 'epoch': each fuse connection will have the
current epoch initialized and every new dentry will have it's d_time set to
the current epoch value. A new operation will then allow userspace to
increment the epoch value. Every time a dentry is d_revalidate()'ed, it's
epoch is compared with the current connection epoch and invalidated if it's
value is different.

It was reported that kernel and Switch MIB desync in scenario where
a packet is forwarded from a port to another. In such case, the
forwarding is offloaded and the kernel is not aware of the

forward packets between the ports or offload small packets like ARP

real one transmitted and received by the Switch.

Previously the LONG_FORM bit was ignored; and isofs would entirely
misinterpret the date as the wrong format, resulting in garbage

The audit code relies on the fact that kern_path_locked() returned a
path even for a negative dentry. If it doesn't find a valid dentry it
immediately calls:
audit_find_parent(d_backing_inode(parent_path.dentry));
which assumes that parent_path.dentry is still valid. But it isn't since
kern_path_locked() has been changed to path_put() also for a negative
dentry.
Fix this by adding a helper that implements the required audit semantics
and allows us to fix the immediate bleeding. We can find a unified
solution for this afterwards.

Adding link rate and lane count information to i915_display_info makes it
easier and faster to access this data compared to checking kernel logs.
This is particularly beneficial for individuals who are not familiar with
i915 in the following scenarios:
* Debugging DP tunnel bandwidth usage in the Thunderbolt driver.
* During USB4 certification, it is necessary to know the link rate used by
the monitor to prove that the DP tunnel can handle required rates.
* In PHY CTS, when the connector probes are not mounted correctly,
some display lanes may not appear in the DP Oscilloscope, leading to CTS
failures.
This change provides validation teams with an easy way to identify and

During inspecting dtbs_check errors, we found the power domain
setting of DPI node "dp_intf0" is missing. Add power domain setting
to "MT8195_POWER_DOMAIN_VDOSYS0" for "dp_intf0"

The public datasheets of the following Amlogic SoCs describe a typical
resistor value for the built-in pull up/down resistor:
- Meson8/8b/8m2: not documented
- GXBB (S905): 60 kOhm
- GXL (S905X): 60 kOhm
- GXM (S912): 60 kOhm
- G12B (S922X): 60 kOhm
- SM1 (S905D3): 60 kOhm
The public G12B and SM1 datasheets additionally state min and max
values:
- min value: 50 kOhm for both, pull-up and pull-down
- max value for the pull-up: 70 kOhm
- max value for the pull-down: 130 kOhm
Use 60 kOhm in the pinctrl-meson driver as well so it's shown in the
debugfs output. It may not be accurate for Meson8/8b/8m2 but in reality
60 kOhm is closer to the actual value than 1 Ohm.

Mark the regmap_config as static const since it is only used in this file
and never modified, allowing the compiler to optimize it and enforce
const-correctness.
Also fix minor indentation inconsistencies in function parameter alignment
to conform with kernel coding style.

The anx7625 driver is open coding what devm_pm_runtime_enable() does.
Switch to the common helper instead.

Currently if no group is matched and found, this function will return
the last grp to the caller, this is not expected, it is supposed to
return NULL in this case.

Amlogic A5 SoCs uses the same pintrl controller as A4 SoCs. There is
no need for an extra compatible line in the driver, but add A5
compatible line for documentation.

Add all of the Multimedia Data Path 3 (MDP3) related nodes
including its Mutex instances, one for each VPPSYS block, and
all of its DMA controllers, Film Grain (FG), HDR, Adaptive Ambient
Light (AAL), Frame Resizer (RSZ), Tone Curve Conversion (TCC),
Two-Dimensional Sharpness (TDSHP), and others, enabling the entire
MDP3 macro-block.
