[media] exynos-gsc: Handle ctx job finish when aborted

2013-10-28T17:21:58+00:00

When the current context is running,
1] If release() or streamoff() is called on the current context,
   it waits until the job is aborted or finished.
2] If the job is finished, driver will call the v4l2_m2m_job_finish().
3] If the job is aborted inside device_run callback, then driver
   has to inform the v4l2 mem2mem framework about the same by calling
   v4l2_m2m_job_finish() with VB2_BUF_STATE_ERROR.

The current code doesn't call v4l2_m2m_job_finish() in the case, where
the job is aborted from the device_run callback. This scenerio is
producing a hang as the other queued contexts are not getting scheduled.

By adding the ABORT state, driver can understand the current job
is aborted and not finished. By checking this flag, driver can call
v4l2_m2m_job_finish() with VB2_BUF_STATE_ERROR.

[media] exynos-gsc: Register v4l2 device

2013-09-03T12:24:21+00:00

Gscaler video device registration was happening without reference to
a parent v4l2_dev causing probe to fail. The patch creates a parent
v4l2 device and uses it for the gsc m2m video device registration.
This fixes regression introduced with comit commit 1c1d86a1ea07506

[media] exynos-gsc: fix s2r functionality

2013-08-18T12:25:41+00:00

When gsc is in runtime suspended state, there is no need to call
m2m_suspend during suspend and similarly, there is no need to call
m2m_resume during resume if already in runtime suspended state. This
patch adds the necessary conditions to achieve this.

[media] exynos-gsc: Remove redundant use of of_match_ptr macro

2013-06-13T00:51:14+00:00

This is a DT only driver and exynos_gsc_match is always compiled
in. Hence of_match_ptr is unnecessary.

[media] exynos-gsc: Add copy time stamp handling

2013-04-25T12:48:04+00:00

Since the introduction of the timestamp_type field, it is necessary that
the driver chooses which type it will use. This patch adds support for
the timestamp_type.

[media] exynos: remove unnecessary header inclusions

2013-04-04T22:52:41+00:00

In multiplatform configurations, we cannot include headers
provided by only the exynos platform. Fortunately a number
of drivers that include those headers do not actually need
them, so we can just remove the inclusions.

[media] exynos-gsc: send valid m2m ctx to gsc_m2m_job_finish

2013-03-21T21:23:06+00:00

gsc_m2m_job_finish() has to be called with the m2m context for the necessary
cleanup while resume. But currently gsc_m2m_job_finish() always passes m2m
context as NULL.
This patch preserves the context before making it null, for necessary cleanup.
Use gsc_m2m_opened() instead gsc_m2m_active() in gsc_resume().

[media] media: Convert to devm_ioremap_resource()

2013-02-06T11:33:04+00:00

Convert all uses of devm_request_and_ioremap() to the newly introduced
devm_ioremap_resource() which provides more consistent error handling.
devm_ioremap_resource() provides its own error messages so all explicit
error messages can be removed from the failure code paths.
