This patch series enables the csi2rx_err_irq interrupt to record any errors that occur during streaming. It also adds support for the VIDIOC_LOG_STATUS ioctl, which outputs the current device status to the kernel log. The IRQ handler records any errors encountered during streaming. Additionally, VIDIOC_LOG_STATUS can be invoked from user space to retrieve the latest status. Changelog: Changes in v3: - Address Krzysztof's review comment to drop minItems from the bindings. - Collect Acked-by from Krzysztof. - Address Jai's review comment to enable FIFO overflow bits in the mask only for the source pads that have an active remote. - Drop TI-specific interrupt and have support for only two interrupts that are common across all vendors. - Address Changhuang's review to use pdev directly to get the interrupt. - Set the interrupt mask register only if the interrupt is defined in the DT.
