[PATCH v5 0/3] Add support for MIPID02 CSI-2 to PARALLEL bridge I2C device

[Mickael Guene <mickael.guene@st.com>]

Hi,

This is the v5 of my MIPID02 series which introduces support of
STMicroelectronics MIPID02 CSI-2 to PARALLEL I2C bridge. It allows using a CSI-2
sensor with a PARALLEL interface. Current driver implementation doesn't support
CSI-2 second input port usage. It doesn't support also YUV420, RGB565 and RGB444
input formats.

Thanks to Sakari for review.

Changes in v5:
- Typo
- Remove useless MEDIA_CONTROLLER from Kconfig
- Replace v4l2_fwnode_endpoint_alloc_parse usage by v4l2_fwnode_endpoint_parse
  since not more variable size data usage
- Add missing mutex_destroy calls
- Switch to probe_new since I²C ID table is not used
- Add new patch to add MEDIA_BUS_FMT_BGR888_3X8 needed output format
- Add MEDIA_BUS_FMT_BGR888_3X8 usage in serial_to_parallel_code

Changes in v4:
- Fix and clarify endpoints properties documentation
- Add support of enum_mbus_code
- Only use V4L2_CID_PIXEL_RATE to compute link speed
- Use MEDIA_BUS_FMT_UYVY8_1X16 instead of MEDIA_BUS_FMT_UYVY8_2X8 for CSI-2 link
- Fix miscellaneous typos
- Fix wrong code behavior for set_fmt and get_fmt

Changes in v3:
- Fix potential wrong error code for mipid02_stream_disable and mipid02_stream_enable
- Remove useless memset for ep in mipid02_parse_rx_ep and mipid02_parse_tx_ep
- Add second CSI-2 input pad even if it's not yet supported
- Add support of get_fmt, set_fmt and link_validate and only access subdev connected to mipid02

Changes in v2:
- Add precision about first CSI-2 port data rate
- Document endpoints supported properties
- Rename 'mipid02@14' into generic 'csi2rx@14' in example
- Merge MAINTAINERS patch 3 into patch 1 and 2
- Fix line too long in Kconfig
- Add missing delay after reset release
- Various style fixes
- Fix mipid02_stream_enable returning no error when mipid02_find_sensor failed
