From: Naushir Patuck <naush@raspberrypi.com>
Date: Fri, 28 Jul 2023 12:00:40 +0100
Subject: [PATCH 0487/1085] drivers: media: imx296: Add standby delay during
probe
Add a 2-5ms delay when coming out of standby and before reading the
sensor info register durning probe, as instructed by the datasheet. This
standby delay is already present when the sensor starts streaming.

Subject: [PATCH] drivers: media: bcm2835_isp: Cache LS table dmabuf
Clients such as libcamera do not change the LS table dmabuf on every
frame. In such cases instead of mapping/remapping the same dmabuf on
every frame to send to the firmware, cache the dmabuf once and only
update and remap if the dmabuf has been changed by the userland client.

Subject: [PATCH] pwm: Add GPIO PWM driver
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
commit 7f61257cd6e1ad4769b4b819668cab00f68f2556 upstream.
Add a software PWM which toggles a GPIO from a high-resolution timer.
This will naturally not be as accurate or as efficient as a hardware
PWM, but it is useful in some cases. I have for example used it for
evaluating LED brightness handling (via leds-pwm) on a board where the
LED was just hooked up to a GPIO, and for a simple verification of the
timer frequency on another platform.
Since high-resolution timers are used, sleeping GPIO chips are not
supported and are rejected in the probe function.

Add two quirk properties that control whether or not the controller
issues many more handshakes to FS/HS Async endpoints in a single

endpoints that frequently respond with NAKs.

Subject: [PATCH] usb: dwc3: core: add support for setting NAK enhancement bits
for FS/HS
If a device frequently NAKs, it can exhaust the scheduled handshakes in
a frame. It will then not get polled by the controller until the next
frame interval. This is most noticeable on FS devices as the controller
schedules a small set of transactions only once per full-speed frame.
Setting the ENH_PER_NAK_FS/LS bits in the GUCTL1 register increases the
number of transactions that can be scheduled to Async (Control/Bulk)
endpoints in the respective frame time. In the FS case, this only
applies to FS devices directly connected to root ports.

Subject: [PATCH] drivers: usb: xhci: prevent a theoretical race on
non-coherent platforms
For platforms that have xHCI controllers attached over PCIe, and
non-coherent routes to main memory, a theoretical race exists between
posting new TRBs to a ring, and writing to the doorbell register.
In a contended system, write traffic from the CPU may be stalled before
the memory controller, whereas the CPU to Endpoint route is separate
and not likely to be contended. Similarly, the DMA route from the
endpoint to main memory may be separate and uncontended.
Therefore the xHCI can receive a doorbell write and find a stale view
of a transfer ring. In cases where only a single TRB is ping-ponged at
a time, this can cause the endpoint to not get polled at all.
Adding a readl() before the write forces a round-trip transaction
across PCIe, definitively serialising the CPU along the PCI
producer-consumer ordering rules.

Subject: [PATCH] iio: humidity: dht11: Allow non-zero decimals
The DHT11 datasheet is pretty cryptic, but it does suggest that after
each integer value (humidity and temperature) there are "decimal"
values. Validate these as integers in the range 0-9 and treat them as
tenths of a unit.

Subject: [PATCH] drm/vc4: Correct condition for ignoring a plane to src rect
=0, not <1.0
The logic for dropping a plane less than zero didn't account for the
possibility that a plane could be being upscaled with a src_rect with
width/height < 1 pixel, but not 0 subpixels.
Check for not 0 subpixels, not < 1, in both vc4 and vc6 paths.
Fixes: dac616899f87 ("drm/vc4: Drop planes that have 0 destination size")
Fixes: f73b18eb0d48 ("drm/vc4: Drop planes that are completely off-screen")

Subject: [PATCH] drm/vc4: Use the TPZ scaling filter for 1x1 source images
The documentation says that the TPZ filter can not upscale,
and requesting a scaling factor > 1:1 will output the original
image in the top left, and repeat the right/bottom most pixels
thereafter.
That fits perfectly with upscaling a 1x1 image which is done
a fair amount by some compositors to give solid colour, and it
saves a large amount of LBM (TPZ is based on src size, whilst
PPF is based on dest size).
Select TPZ filter for images with source rectangle <=1.

The non-desktop property "Indicates the output should be ignored for
purposes of displaying a standard desktop environment or console."
That sounds like it should be true for all writeback and virtual
connectors as you shouldn't render a desktop to them, so set it
by default.

Subject: [PATCH] drm/vc4: Increase number of overlay planes from 16 to 48
The HVS can accept an arbitrary number of planes, provided
that the overall pixel read load is within limits, and
the display list can fit into the dlist memory.
Now that DRM will support 64 planes per device, increase
the number of overlay planes from 16 to 48 so that the
dlist complexity can be increased (eg 4x4 video wall on
each of 3 displays).

Subject: [PATCH] dmaengine: dw-axi-dmac: Allow client-chosen width
For devices where transfer lengths are not known upfront, there is a
danger when the destination is wider than the source that partial words
can be lost at the end of a transfer. Ideally the controller would be
able to flush the residue, but it can't - it's not even possible to tell
that there is any.
Instead, allow the client driver to avoid the problem by setting a
smaller width.

Subject: [PATCH] drivers: usb: xhci: set HID bit in streaming endpoint
contexts
The xHC may commence Host Initiated Data Moves for streaming endpoints -
see USB3.2 spec s8.12.1.4.2.4. However, this behaviour is typically
counterproductive as the submission of UAS URBs in {Status, Data,
Command} order and 1 outstanding IO per stream ID means the device never
enters Move Data after a HIMD for Status or Data stages with the same
stream ID. For OUT transfers this is especially inefficient as the host
will start transmitting multiple bulk packets as a burst, all of which
get NAKed by the device - wasting bandwidth.
Also, some buggy UAS adapters don't properly handle the EP flow control
state this creates - e.g. RTL9210.
Set Host Initiated Data Move Disable to always defer stream selection to
the device. xHC implementations may treat this field as "don't care,
forced to 1" anyway - xHCI 1.2 s4.12.1.

The default link frequency of 450MHz has been noted to interfere
with GPS if they are in close proximty.
Add the option for 453 and 456MHz to move the signal slightly out
of the band. (447MHz can not be offered as corruption is then observed
on the 133x992 10bit mode).

Subject: [PATCH] dmaengine: dw-axi-dmac: Only start idle channels
Attempting to start a non-idle channel causes an error message to be
logged, and is inefficient. Test for emptiness of the desc_issued list
before doing so.

Subject: [PATCH] mailbox: Add RP1 mailbox support
The Raspberry Pi RP1 includes 2 M3 cores running firmware. This driver
adds a mailbox communication channel to them via a doorbell and some
shared memory.
