Because "i" is unsigned then "i-- >= 0" is always true. If we don't find what we are looking for then we loop forever. Signed-off-by:

Use clk_prepare_enable()/clk_disable_unprepare() instead of separately prearing/unparing the clk_cam clocks. This simplifies the code that is now mostly not going to be used, function __fimc_md_set_camclk() is only left for S5PV210 platform which is not yet converted to Device Tree. Signed-off-by:

If the same callbacks are used for runtime and system suspend/resume, clocks can get disabled twice, which can lead to negative reference counts and kernel warnings. This patch splits suspend/resume callbacks into separate runtime and system-wide functions, so clock gating is done correctly. Signed-off-by:

This patch fixes two errors that caused incorrect format detections: The first bug is in the calculation of the vertical backporch: the combined period of vsync and backporch must *exceed* a certain minimum value, and not be equal to it. The second bug is a rounding error in the reduced blanking calculation: expand the ideal_duty_cylce to be in parts per ten thousand to avoid rounding errors. Signed-off-by:

When streamoff is called on the context and the context is added to the job_queue, 1] sometimes device_run receives the empty vb2 buffers (as v4l2_m2m_streamoff is dropping the ready queue). 2] sometimes v4l2_m2m_job_finish may not succeed as the m2m_dev->curr_ctx is made NULL in the v4l2_m2m_streamoff() The above points may stop the execution of the other queued contexts. This patch makes sure that before streamoff is executed on any context, that context should "not be running" or "not queued" in the job_queue. 1] If the current context is running, then abort job will be called. 2] If the current context is queued, then the context will be removed from the job_queue.
