In jdi_panel_dsi_remove(), jdi is explicitly checked, indicating that it
may be NULL:
if (!jdi)
mipi_dsi_detach(dsi);
However, when jdi is NULL, the function does not return and continues by
calling jdi_panel_disable():
err = jdi_panel_disable(&jdi->base);
Inside jdi_panel_disable(), jdi is dereferenced unconditionally, which can
lead to a NULL-pointer dereference:
struct jdi_panel *jdi = to_panel_jdi(panel);
backlight_disable(jdi->backlight);
To prevent such a potential NULL-pointer dereference, return early from
jdi_panel_dsi_remove() when jdi is NULL.

Printing error messages on pm_runtime_put() returning negative values
is not particularly useful.
Returning an error code from pm_runtime_put() merely means that it has
not queued up a work item to check whether or not the device can be
suspended and there are many perfectly valid situations in which that
can happen, like after writing "on" to the devices' runtime PM "control"
attribute in sysfs for one example.
Accordingly, update mtk_vcodec_enc_pw_off() and mtk_vcodec_dec_pw_off()
to simply discard the return value of pm_runtime_put().
This will facilitate a planned change of the pm_runtime_put() return
type to void in the future.

The min_queued_buffers field controls when start_streaming() is called
by the vb2 core (it delays the callback until at least N buffers are
queued). Setting it to 1 affects the timing of start_streaming(), which
breaks the seek flow in decoder scenarios and causes test failures.
The current driver implementation does not rely on this minimum buffer
requirement and handles streaming start correctly with the default
value of 0, so remove these assignments.

Replace vmalloc/vfree with kmalloc/kfree for allocating small
driver structures (vpu_inst, vdec_t, venc_t, vpu_cmd_t, and
frame objects).
vmalloc() is designed for large memory allocations and incurs
unnecessary overhead for small objects due to virtual memory
mapping. kmalloc() is more appropriate as it allocates physically
contiguous memory with lower overhead.
ftrace measurements of vpu_alloc_cmd() show significant improvement:
Before (vmalloc): 35-72 us (avg ~45.7 us)
After (kmalloc): 11-26 us (avg ~16.8 us)
This reduces allocation time by approximately 63%.

Now that all dependencies for USB 2.0 and 3.x support are either merged
(tipd changes in v6.18, dwc3-apple in v6.19-rc1) or in linux-next (Apple
Type-C PHY) prepare device tree changes to expose the ports.
Each port on Apple silicon devices is driven by a separate collection of
hardware blocks. For USB 2.0 and 3.x the collection consists of:
- Apple Type-C PHY, combo PHY for USB 2.0, USB 3.x, USB4/Thunderbolt and
DisplayPort
- Synopsys Designware dwc3 USB controller
- two DART iommu instances for dwc3
- CD321x USB PD controller (similar to Ti's TPS6598x series)
The CD321x nodes are already present so this series add the remaining
devices nodes, typec connector nodes and connections between all
components.
The devices expose except for a few exceptions noted below all ports. M1
and M2 have two ports, M1 and M2 Pro and Max have four ports and
M1 and M2 Ultra have eight ports.
The Pro and Max based Macbook Pros use only three ports. The fourth port
is used as DisplayPort PHY to drive a HDMI output via an integrated
DP to HDMI converter.
The Ultra based Mac studio devices only use six ports. The third and
fourth port on the second die is completely fused off.
The changes for t600x and t602x are in a single commit since the devices
share .dtsi files across SoC generations due to their similarity.
Depends on commit c1538b87ca ("dt-bindings: phy: Add Apple Type-C
PHY") in linux-phy's [1] next branch for `make dtbs_check` to pass.
checkpatch warns about the undocumented DT compatible strings
"apple,t8112-atcphy", "apple,t6000-atcphy" and "apple,t6020-atcphy" but
not about "apple,t8103-atcphy". I don't under why it doesn't warn about
the last. "apple,t8103-atcphy" is only found in the added devicetree
files and nowhere else in v6.19-rc1.
Tested on top of next-20260106 on M1, M2, M1 Max and M2 Pro Mac mini /
Mac studio and a few fixes for dwc3-apple and atc [2, 3, 4, 5].

The OS has more control about the display pipeline used for the HDMI
output on M2 based devices. The HDMI output is driven by an integrated
DisplayPort to HDMI converter (Parade PS190). The DPTX phy is now
controlled by the OS and no longer by firmware running on the display
co-processor. This allows using the second display controller on the
second USB type-c port or tunneling 2 DisplayPort connections over
USB4/Thunderbolt.
The m1n1 bootloader uses the second display controller to drive the HDMI

Currently MDP5 3.x (MSM8998, SDM630 and SDM660) platforms are support
by both DPU and MDP5 drivers. Support for them in the DPU driver is
mature enough, so it's no longer sensible to keep them enabled in the
MDP5 driver. Not to mention that MSM8998 never used an MDP5 compatible
string. Drop support for the MDP5 3.x genration inside the MDP5
driver and migrate those to the DPU driver only.
Note: this will break if one uses the DT generated before v6.3 as they
had only the generic, "qcom,mdp5" compatible string for SDM630 and
SDM660. However granted that we had two LTS releases inbetween I don't
think it is an issue.

net: stmmac: pcs: clean up pcs interrupt handling
Clean up the stmmac PCS interrupt handling:
- Avoid promotion to unsigned long from unsigned int by defining PCS
register bits/fields using u32 macros.
- Pass struct stmmac_priv into the host_irq_status MAC core method.
- Move the existing PCS interrupt handler (dwmac_pcs_isr) into
stmmac_pcs.c, change it's arguments, use dev_info() rather than
pr_info()
- arrange to call phylink_pcs_change() on link state changes.

Report PCS link changes to phylink, which will allow phylink's inband
support to respoind to link events once the PCS is appropriately
configured.
An expected behavioural change is that should the PCS report that its
link has failed, but phylink is operating in outband mode and the PHY
reports that link is up, this event will cause the netdev's link to
momentarily drop, making the event more noticable, rather than just
producing a "stmmac_pcs: Link Down" message.

Change the arguments to the PCS handler so that it can access the
struct device pointer and integrated PCS pointers.
This allows us to use the PCS register offset stored in struct
stmmac_pcs rather than passing it into the function, and also allows
the messages to be printed using dev_info() rather than pr_info(),
thereby allowing the stmmac instance to be identified.
Finally, as dev_info() identifies the driver/device, prefixing with
"stmmac_pcs: " is now redundant, so replace this with just "PCS ".

Rather than passing struct mac_device_info to the host_irq_status()
method, pass struct stmmac_priv so that we can pass the integrated
PCS to the PCS interrupt handler.

dwmac_pcs_isr() doesn't need to be inlined into the MAC's
host_irq_status method, as handling PCS interrupts isn't performance
critical. However, there is little point calling this function unless
an interrupt is pending for the PCS.
Rename it to stmmac_integrated_pcs_irq() while moving it.
