Subject: [PATCH v5 0/5] Add OV5640 parallel interface and RGB565/YUYV support
Date: Wed, 3 Jan 2018 10:57:27 +0100	[thread overview]
Message-ID: <1514973452-10464-1-git-send-email-hugues.fruchet@st.com> (raw)

Enhance OV5640 CSI driver to support also DVP parallel interface.
Add RGB565 (LE & BE) and YUV422 YUYV format in addition to existing
YUV422 UYVY format.
Some other improvements on chip identifier check and removal
of warnings in powering phase around gpio handling.

    https://www.mail-archive.com/linux-media-u79uwXL29TY76Z2rM5mHXA@public.gmane.org/msg122575.html
  - Use 16 bits register read for this check as per Steve Longerbeam comment:
    https://www.mail-archive.com/linux-media-u79uwXL29TY76Z2rM5mHXA@public.gmane.org/msg122692.html
  - Update bindings to document parallel mode support as per Fabio Estevam comment:
    https://www.mail-archive.com/linux-media-u79uwXL29TY76Z2rM5mHXA@public.gmane.org/msg122576.html
  - Enable the whole 10 bits parallel output and document 8/10 bits support
    in ov5640_set_stream_dvp() to answer to Steve Longerbeam comment:
    https://www.mail-archive.com/linux-media-u79uwXL29TY76Z2rM5mHXA@public.gmane.org/msg122693.html

    https://www.mail-archive.com/linux-media-u79uwXL29TY76Z2rM5mHXA@public.gmane.org/msg122259.html
  - Revisit ov5640_set_stream_dvp() to only configure DVP at streamon
  - Revisit ov5640_set_stream_dvp() implementation with fewer register settings

version 1:
  - Initial submission
