Subject: [PATCH v2 0/8] Add support for DCMI camera interface of STMicroelectronics STM32 SoC series
This patchset introduces a basic support for Digital Camera Memory Interface
(DCMI) of STMicroelectronics STM32 SoC series.
This first basic support implements RGB565 & YUV frame grabbing.
Cropping and JPEG support will be added later on.
This has been tested on STM324x9I-EVAL evaluation board embedding
an OV2640 camera sensor.
This driver depends on:
- [PATCHv6 00/14] atmel-isi/ov7670/ov2640: convert to standalone drivers http://www.spinics.net/lists/linux-media/msg113480.html
===========

===========
version 2:
- Fix a Kbuild warning in probe:
http://www.mail-archive.com/linux-media@vger.kernel.org/msg110678.html
- Fix a warning in dcmi_queue_setup()
- dt-bindings: warn on sensor signals level inversion in board example
- Typos fixing
version 1:
- Initial submission
