This iteration includes couple bug fixes and minor cleanup comparing
to the original version (original cover letter can be found below).
A patch adding ISP capture node has been removed as I'll need more
time to enable this feature and I'd like to possibly have this series
included in 3.10.
-------
This patch series is an initial version of a driver for the camera ISP
subsystem (FIMC-IS) found in Samsung Exynos4x12 SoCs.
The FIMC-IS subsystem is build around a ARM Cortex-A5 CPU that controls
its dedicated peripherals, like I2C, SPI, UART, PWM, ADC,... and the
ISP chain. There are 3 hardware image processing blocks: ISP, DRC
(dynamic range compression) and FD (face detection) that are normally
controlled by the Cortex-A5 firmware.
The driver currently exposes two additional sub-devices to user space:
the image sensor and FIMC-IS-ISP sub-device. Another one might be
added in future for the FD features.
The FIMC-IS has various data inputs, it can capture data from memory
or from other SoC IP blocks (FIMC-LITE). It is currently plugged
between FIMC-LITE and FIMC IP blocks, so there is a media pipeline
like:
sensor -> MIPI-CSIS -> FIMC-LITE -> FIMC-IS-ISP -> FIMC -> memory
A raw Bayer image data can be captured from the ISP block which has
it's own DMA engines. Support for this is not really included in
this series though, only a video capture node driver stubs are added.
This is a bit complicated code, nevertheless I would really appreciate
any review comments you might have.
And this is just a basic set of futures this patch series addresses.
Others include input/output DMA support for the DRC and FD blocks,
support for more ISP controls, etc.
