Amlogic S6/S7/7D SoCs uses the same UART controller as S4 SoCs and G12A.
There is no need for an extra compatible line in the driver, but
add S6/S7/S7D compatible line for documentation.

mxser enables its PCI device with pcim_enable_device(). This,
implicitly, switches the function pci_request_region() into managed
mode, where it becomes a devres function.
The PCI subsystem wants to remove this hybrid nature from its
interfaces. To do so, users of the aforementioned combination of
functions must be ported to non-hybrid functions.
Replace the call to sometimes-managed pci_request_region() with one to
the always-managed pcim_request_region().

The dt-core typically allows multiple compatibles[1] but usb-device
currently forces a single compatible.
This is an issue when multiple devices with slightly different productID
all behave the same. This would require the driver to keep updating its
compatible matching table to include this new productID instead of doing
what is usually done: have two compatibles, the leftmost which matches
exactly the HW device definition, and the rightmost one as a fallback
which is assumed to be 100% compatible with the device at hand. If this
assumption turns out to be wrong, it is easy to work around this without
having to modify the device tree by handling the leftmost compatible in the driver.

During ucsi_cmd() we see:
if (ret < 0) {
ucsi->debugfs->status = ret;
return ret;
}
But "status" is u32 meaning unsigned wrap-around occurs when assigning a value which is < 0 to it, this obscures the real status.
To fix this make the "status" of type int since ret is also of type int.

usb_hub_to_struct_hub() can return NULL in certain scenarios,

Plus, all other places that call usb_hub_to_struct_hub() in the same file
do check for NULL return values.
If usb_hub_to_struct_hub() returns NULL, the subsequent access to

Document the Renesas USBHS controller found on the Renesas RZ/V2H(P) SoC.
The USBHS block on RZ/V2H(P) is functionally identical to the one on the
RZ/G2L family, so no driver changes are needed. The existing
"renesas,rzg2l-usbhs" fallback compatible will continue to be used for
handling this IP.
In addition, update the schema validation logic by replacing the enum list
of SoC-specific compatibles with a const "renesas,rzg2l-usbhs" as all
listed SoCs share identical USBHS hardware and already include the fallback
compatible. This will help to simplify the schema and avoid redundancy.

But as handle_remove only works on inodes created and owned by devtmpfs
itself there is no need to use vfs_getattr_nosec vs simply reading the

Fix improper use of dct_active_percent field in DCT interrupt handler
causing DCT to never get enabled. Set dct_active_percent internally before
IPC to ensure correct driver value even if IPC fails.
Set default DCT value to 30 accordingly to HW architecture specification.

Replace the custom mutex in the imx334 driver with the V4L2 subdev state
lock for control synchronization. Initialize the subdev with
v4l2_subdev_init_finalize in imx334_probe, adding proper cleanup in error
paths and imx334_remove. This aligns the driver with V4L2 standards.

Runtime PM is fully initialized before calling
v4l2_async_register_subdev_sensor(). Moving the runtime PM initialization
earlier prevents potential access to an uninitialized or powered-down
device.
