[PATCH v4] Add v4l2 subdev driver for S5P MIPI-CSI receivers

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,

this is a fourth version of the subdev driver for MIPI-CSI2 receivers
present on S5PVx10 and EXYNOS4 SoCs.
This patch set also adds a V4L2_MBUS_FMT_JPEG_1X8 media bus format
and moves the s5p-fimc driver to Video Capture Devices kconfig group.

I don't expect this driver to undergo any major changes and hope to have
it added in kernel 2.6.40.
 
Any comments are welcome!

Changes since v1:
 - added runtime PM support
 - conversion to the pad ops

Changes since v2:
 - added reference counting in s_stream op to allow the mipi-csi subdev
   to be shared by multiple FIMC instances
 - added support for TRY format in pad get_fmt op
 - added pm_runtime* calls in s_stream op to avoid a need for explicit
   s_power(1) call
 - corrected locking around the pad ops, minor bug fixes

Changes since v3:
 - slighty reworked the power management part
 - removed a reference counting in s_stream op as this should be handled
   on a media device and the pipeline level
 - s5p_csis_ prefix renamed to s5pcsis_
 - updated the help text in Kconfig
