Ensure that the frame sequence counter is incremented only if a previous frame start interrupt has occurred, or a frame start + frame end has occurred simultaneously. This corresponds the sequence number with the actual number of frames produced by the sensor, not the number of frame buffers dequeued back to userland.

Arducam 64MP has specific requirements for the line length, and if these conditions are not met, the camera will not function properly. Under the previous configuration, once a stream off operation is performed, the camera will not output any data, even if a stream on operation is performed. This prevents us from switching from 1280x720 to another resolution. Signed-off-by: Lee Jackson <[email protected]>

The VL805 controller can't cope with the TR Dequeue Pointer for an endpoint being set to a Link TRB. The hardware-maintained endpoint context ends up stuck at the address of the Link TRB, leading to erroneous ring expansion events whenever the enqueue pointer wraps to the dequeue position. If the search for the end of the current TD and ring cycle state lands on a Link TRB, move to the next segment.

This reimplements 5a57342 usb: xhci: add VLI_TRB_CACHE_BUG quirk The downstream implementation required a fair bit of driver surgery to allow for truncated ring segments, which needed to shrink by a small amount to avoid the cache prefetcher from reading off the end of one segment and into another. An upstream implementation for a similar bug on a different controller just doubles the size of the memory allocated for ring segments, which is a bit more wasteful (+4K per allocation) but means less code churn. Signed-off-by: Jonathan Bell <[email protected]>
The VL805 can cause data corruption if a SS Bulk OUT endpoint enters a flow-control condition and there are TRBs in the transfer ring that are not an integral size of wMaxPacket and the endpoint is behind one or more hubs. This is frequently the case encountered when FAT32 filesystems are present on mass-storage devices with cluster sizes of 1 sector, and the filesystem is being written to with an aggregate of small files. The initial implementation of this quirk separated TRBs that didn't adhere to this limitation into two - the first a multiple of wMaxPacket and the second the 512-byte remainder - in an attempt to force TD fragments to align with packet boundaries. This reduced the incidence rate of data corruption but did not resolve it. The fix as recommended by VIA is to disable bursts if this sequence of TRBs can occur. Limit turning off bursts to just USB mass-storage devices by searching the device's configuration for an interface with a class type of USB_CLASS_MASS_STORAGE.

The integrated USB2.0 hub in the VL805 chipset has a bug where it incorrectly determines the remaining available frame time before the host next sends a SOF packet with an incremented frame_number. See the USB2.0 specification sections 11.3 and 11.14.2.3. The hub's non-periodic TT handler can transmit the IN/OUT handshake token too late, so a following 64-byte DATA0/1 packet causes the ACK handshake to collide with the propagated SOF. This causes port babble. Avoid ringing doorbells for vulnerable endpoints during uFrame 7 if the TR is Idle to stop one source of babble. An IN transfer for a Running TR may happen at any time, so there's not much we can do about that. Ideally a hub firmware update to properly implement frame timeouts is needed, and to avoid spinning for up to 125us when submitting TDs to Idle rings. Signed-off-by: Jonathan Bell <[email protected]> xhci: constrain XHCI_VLI_HUB_TT_QUIRK to old firmware versions VLI have a firmware update for the VL805 which resolves the incorrect frame time calculation in the hub's TT.

For "Really Good Reasons" [1] the SPI core requires a match between compatible device strings and the name in spi_device_id. The ili9486 driver uses compatible strings "waveshare,rpi-lcd-35" and "ozzmaker,piscreen", but "rpi-lcd-35" and "piscreen" are missing, so add them. Compatible string "ilitek,ili9486" is already used by staging/fbtft/fb_ili9486, therefore leaving it present in ili9486 as an spi_device_id causes the incorrect module to be loaded, therefore remove this id.

The SPI core logs error messages if a compatible string device name is not also present as an spi_device_id. No spi_device_id values are specified by the driver, therefore we get 4 log lines every time it is loaded: SPI driver ads7846 has no spi_device_id for ti,tsc2046 SPI driver ads7846 has no spi_device_id for ti,ads7843 SPI driver ads7846 has no spi_device_id for ti,ads7845 SPI driver ads7846 has no spi_device_id for ti,ads7873 Add the spi_device_id values for these devices.

Based on bcm2835-gpiomem. We allow export of the "GPIO registers" to userspace via a chardev as this allows for finer access control (e.g. users must be group gpio, root not required). This driver allows access to either rp1-gpiomem or gpiomem, depending on which nodes are populated in devicetree. RP1 has a different look-and-feel to BCM283x SoCs as it has split ranges for IO controls and the parallel registered OE/IN/OUT access. To handle this, the driver concatenates the ranges for an IO bank and the corresponding RIO instance into a contiguous buffer. Signed-off-by: Jonathan Bell <[email protected]>

Pi 5 uses BL31 as its armstub file, so the reset goes via PSCI. Parse any "reboot" parameter as a partition number to reboot into. N.B. This code path is only used if reboot mode has been set to warm or soft. Signed-off-by: Phil Elwell <[email protected]>
Switch to warm reboot mode so that the partition number is preserved. Signed-off-by: Phil Elwell <[email protected]>
Set snps,parkmode-disable-ss-quirk for usb0 and usb1. Enabling this test/debug feature seems to prevent controller lockups with bidirectional SS bulk endpoints active. Signed-off-by: Jonathan Bell <[email protected]>
Don't assume the camera has been reset each time we start streaming, but always write registers relating to trigger_mode, even in mode 0. IMX477: Stop driving XVS on stop streaming, to avoid spurious pulses. Signed-off-by: Nick Hollinghurst <[email protected]>
Leave the camera's power supplies up, to prevent the camera clamping its 1.8V digital I/Os to ground. This may be useful when synchronizing multiple camera systems using XVS or XTRIG. Signed-off-by: Nick Hollinghurst <[email protected]>
snprintf takes the length of the array that we can print into, and has to fit the NULL terminator in there too. Printing the prefix is generally "12-3456 " which is 8 desired characters (the length of EDT_NAME_PREFIX_LEN) and the NULL. The space is therefore being truncated to fit the NULL in. Increase the length snprintf is allowed to use. Signed-off-by: Dave Stevenson <[email protected]>
This change removes the subdev state management at the driver level for the bcm2835 unicam driver to instead opt for the v4l2-core's state management. Signed-off-by: Vinay Varma <[email protected]>

subdev drivers that use the v4l2-core for for state management, need the same active/try state passed in for the pad ops.
