[media] s5p-fimc: Add support for Exynos4x12 FIMC-LITE · 4af81310

由 Sylwester Nawrocki 提交于 4月 27, 2012

This patch adds driver for FIMC-LITE camera host interface. This new IP
differs from the regular FIMC IP in that it doesn't have input DMA,
scaler and color space conversion support. So it just plain camera host
interface for MIPI-CSI2 and ITU-R interfaces. For the serial bus support
it interworks with MIPI-CSIS and the exisiting s5p-csis driver.
The FIMC-LITE and MIPI-CSIS drivers can also be reused in the Exynos5
SoC series.

Use dev_name() for requesting an interrupt so we don't get an interrupt
requested with same name for multiple device instances.

[media] s5p-fimc: Minor cleanups · bb7c276e

由 Sylwester Nawrocki 提交于 4月 27, 2012

Tidy up the variant and driver data handling. Remove the 'samsung_'
prefix from some data structures since it doesn't really carry any
useful information and makes the names unnecessarily long.

[media] s5p-fimc: Prefix format enumerations with FIMC_FMT_ · 3d112d9a

由 Sylwester Nawrocki 提交于 4月 26, 2012

Prefix the pixel format enumerations with FIMC_FMT_ to make it more clear,
especially when used in new IP drivers, like fimc-lite, etc. Also add IO_
prefix in the input/output enumeration.

[media] s5p-fimc: Rework the video pipeline control functions · 0f735f52

由 Sylwester Nawrocki 提交于 4月 27, 2012

There is getting more entities to manage within single video pipeline
in newer SoCs. To simplify code put subdevs' pointer into an array
rather than adding new member in struct fimc_pipeline for each subdev.
This allows to easier handle subdev operations in proper order.

Additionally walk graph in one direction only in fimc_pipeline_prepare()
function to make sure we properly gather only media entities that below
to single data pipeline. This avoids wrong initialization in case where,
for example there are multiple active links from s5p-mipi-csis subdev
output pad.

struct fimc_pipeline declaration is moved to the driver's public header
to allow other drivers to reuse the fimc-lite driver added in subsequent
patches.

[media] s5p-fimc: Use v4l2_subdev internal ops to register video nodes · 693f5c40

由 Sylwester Nawrocki 提交于 4月 20, 2012

In order to be able to select only FIMC-LITE support, which is added
with subsequent patches, the regular FIMC support is now contained
only in fimc-core.c, fimc-m2m.c and fimc-capture.c files. The graph
and pipeline management is now solely handled in fimc-mdevice.[ch].
This means the FIMC driver can now be excluded with Kconfig option,
leaving only FIMC-LITE and allowing this driver to be reused in SoCs
that have only FIMC-LITE and no regular FIMC IP.

[media] s5p-fimc: Avoid crash with null platform_data · 41df5bf0

由 Sylwester Nawrocki 提交于 4月 30, 2012

In commit "s5p-fimc: Handle sub-device interdependencies using deferred.."
there was a check added for pdata->num_clients without first checking
pdata against NULL. This causes a crash when platform_data is not set,
which is a valid use case. Fix this regression by skipping the MIPI-CSIS
subdev registration also when pdata is null.
