This patch series adds support for the TI VIP. VIP stands for Video
Input Port, it can be found on devices such as DRA7xx and provides
a parallel interface to a video source such as a sensor or TV decoder.

Each VIP can support two inputs (slices) and a SoC can be configured
with a variable number of VIP's. Each slice can support two ports
each connected to its own sub-device.

Note: The main intention behind updating this series is to address
the warnings reported by Media CI at [1].

Changelog:
Changes in v7: 
- Fix overflow warning by casting to u32 while doing reg_write in enable_irqs(). (Media CI)
- In function add_out_dtd(), initialize max_width and max_height by replacing else if
  with else to avoid possible use of uninitialized variables warning. (Media CI)
- Add missing error code when video_device_alloc() fails in alloc_stream(). (Media CI)
- Fix inconsistent indentation in switch-case block in vip_probe_complete(). (Media CI)
- Correct pm_runtime_get_sync() handling in vip_probe() by checking ret < 0 instead of ret. (Media CI)
- Add missing goto path when we fail to ioremap in vip_probe() for proper error handling. (Media CI)
- Avoid passing zero to PTR_ERR() in vip_probe_slice() by using PTR_ERR_OR_ZERO(). (Media CI)
- Prevent possible NULL dereference in vip_process_buffer_complete() by using list_first_entry_or_null(). (Media CI)

driver in various capacities in our downstream tree. Before starting the upstreaming effort,
I reached out to Dale, Benoit, and Sukruth and obtained their consent to retain their respective
