during system resume, interconnect bandwidth would currently be requested even though the device is runtime suspended. This leaves the system in an unbalanced state. Fix that by only doing that in runtimem pm and splitting up runtime and system suspend to be a more readable: imx8mq_mipi_csi_pm_*() does the generic things called from system- and runtime functions that each do specific things on top.

The place where this register writel() that masks one interrupt is placed does not guarantee that the device is powered so that's not allowed. Moreover imx8mq_mipi_csi_start_stream() masks the interrupt anyway so the write is not even needed. Remove it as this is a mistake that slipped in with the driver.

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.

The specification for VIDIOC_DQBUF is slightly ambiguous on what fields of |struct v4l2_buffer| is filled by the driver. Reword it so things are clear: the driver fills in all remaining fields not specified to be filled in by userspace applications. Signed-off-by:

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. Signed-off-by:

When multiple CSIS instances are present in a single graph, they are currently all named "imx7-mipi-csis.0", which breaks the entity name uniqueness requirement.

Similar to the SM8250 the CSID relies on the VFE to be clocked prior to taking the CSID out of reset. Apply the same fixup to SDM845 as SM8250. Suggested-by:

The sm8250 CAMSS CSID depends on the VFE it is attached to being powered on and clocked prior to taking the CSID out of reset. It is possible to open just the CSID subdev from libcamera and attempt to bring the CSID block up. If we do not first bring up the VFE the CSID will fail to come out of reset. Tested-by:

Downstream makes some pretty explicit comments about voting for bus bandwidth prior to camcc_camnoc_axi_clk_src. Working with camx downstream also shows that the bandwidth vote is required to get that root clock working. Add a simple mechanism to declare set and unset named NOCs. Whereas the objective is to enable the sm8250 specifically the code has been implemented to allow setting of whatever NOCs different SoCs using this driver may require. Tested-by:

The Titan 480 camss found on SM8250 has 6 CSIPHY and 4 VFE/CSID. CSID is compatible with the Titan 170 CSID, but the Titan 480 CSID are inside the VFE region (between the "top" and "bus" registers), so a workaround is added to avoid ioremap failure.

csid_isr() only checks for the reset irq, so enabling any other irqs doesn't make sense. The "RDI irq" comment is also wrong, the register should be CSID_CSI2_RDIN_IRQ_MASK.
