2022-01-28media: vsp1: Use platform_get_irq() to get the interruptLad Prabhakar1-8/+6
platform_get_resource(pdev, IORESOURCE_IRQ, ..) relies on static allocation of IRQ resources in DT core code, this causes an issue when using hierarchical interrupt domains using "interrupts" property in the node as this bypasses the hierarchical setup and messes up the irq chaining. In preparation for removal of static setup of IRQ resource from DT core code use platform_get_irq().

2022-01-28media: i2c: max9286: Use "maxim,gpio-poc" propertyJacopo Mondi1-30/+90
The 'maxim,gpio-poc' property is used when the remote camera power-over-coax is controlled by one of the MAX9286 gpio lines, to instruct the driver about which line to use and what the line polarity is. Add to the max9286 driver support for parsing the newly introduced property and use it if available in place of the usual supply, as it is not possible to establish one as consumer of the max9286 gpio controller. If the new property is present, no gpio controller is registered and 'poc-supply' is ignored. In order to maximize code re-use, break out the max9286 gpio handling function so that they can be used by the gpio controller through the gpio-consumer API, or directly by the driver code. Wrap the power up and power down routines to their own function to be able to use either the gpio line directly or the supply. This will make it easier to control the remote camera power at run time.

This IR receiver has two limitations: 1) Any IR pulse or space longer than 12ms will be truncated to 12ms 2) Any pulses/spaces after the first 68 are lost ir_raw_event_reset() won't help here. If the IR cannot be decoded, any decoder should reset itself, and if it does not, this is a bug in the decoder.

2022-01-24media: mtk-cir: reduce message end to fix nec repeatsSean Young1-4/+5
The ir receiver generates an interrupt with the IR data, once a space of at least ok_count is has been seen. Currently this is about 110ms; when holding down a button on a nec remote, no such space is seen until the button is released. This means nothing happens until you release the button. The sample rate is fixed at 46us, so the maximum space that can be encoded is about 12ms. So, the set ok_count above that at 23ms.

When a driver reports a timeout, no more IR activity will be reported until the next pulse. A space is inserted between the timeout and the next pulse, based on ktime. The timeout reports already a duration, so this duration should not be added to the gap. Otherwise there is no change to the functionality.

The bytesperline field of the pixfmt should be only for the first plane in case of planar formats like YUV420 or YUV422. The bytesperline is used by the driver to compute the framesize. We have to report a different bpp (bytes per pixel) to v4l2 in bytesperline than the actual bpp. For example for YUV420, the real bpp is 12, but the first plane has only 8 bpp. Thus we report a bytesperline 8*width instead of 12*width. However, for real framezise we have to compute 12*width*height. Hence added a new variable to hold this information and to correctly compute the frame size.

The driver allocates and registers two platform device structures during probe, but the devices were never deregistered on driver unbind. This results in a use-after-free on driver unbind as the device structures were allocated using devres and would be freed by driver core when remove() returns. Fix this by adding the missing deregistration calls to the remove() callback and failing probe on registration errors. Note that the platform device structures must be freed using a proper release callback to avoid leaking associated resources like device names.

2022-01-23media: v4l2-mem2mem: Apply DST_QUEUE_OFF_BASE on MMAP buffers across ioctlsChen-Yu Tsai1-12/+41
DST_QUEUE_OFF_BASE is applied to offset/mem_offset on MMAP capture buffers only for the VIDIOC_QUERYBUF ioctl, while the userspace fields (including offset/mem_offset) are filled in for VIDIOC_{QUERY,PREPARE,Q,DQ}BUF ioctls. This leads to differences in the values presented to userspace. If userspace attempts to mmap the capture buffer directly using values from DQBUF, it will fail. Move the code that applies the magic offset into a helper, and call that helper from all four ioctl entry points.

2022-01-23media: vivid: fix timestamp and sequence wrappingDeborah Brouwer7-30/+44
The error injection controls that test wrap-around sequence and timestamp counters were partially broken. Add a menu option for 64 or 32 bit signed timestamp wrapping. Prevent the timestamp from wrapping around before the device can be tested. Remove the sequence count from the timestamp calculation so that sequence wrapping does not interfere with the timestamp. Add consistent time and sequence wrapping to sdr and touch devices.
