[PATCH v2 00/13] davinci: add vpif support for da850/omap-l138

add vpif capture and display driver support for da850/omap-l138 by taking care of the interrupt behavior changes, removing platform specific connotations. while doing so fix a bug and add a few feature enhancements for power mangement , clipping and correct contiguous memory allocation strategy.

[PATCH v2 01/13] davinci: vpif: add check for genuine interrupts in the isr

As the same interrupt is shared between capture and display devices, sometimes we get isr calls where the interrupt might not genuinely belong to capture or display. Hence, add a condition in the isr to check for interrupt ownership and channel number to make sure we do not service wrong

[PATCH v2 04/13] davinci: vpif: fix setting of data width in config_vpif_params() function

fix setting of data width in config_vpif_params() function, which was wrongly set. Signed-off-by: Manjunath Hadli manjunath.ha...@ti.com --- drivers/media/video/davinci/vpif.c |2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/drivers/media/video/davinci/vpif.c

[PATCH v2 02/13] davinci: vpif: make generic changes to re-use the vpif drivers on da850/omap-l138 soc

change the dm646x specific strings in the driver to make them generic across platforms. In this case change all the strings which have a dm646x connotation to vpif which is a platform independent ip. Signed-off-by: Manjunath Hadli manjunath.ha...@ti.com --- drivers/media/video/davinci/vpif.c

[PATCH v2 03/13] davinci: vpif: make request_irq flags as shared

omap-l138 shares the interrupt between capture and display. Make sure we are able to request for the same irq number by making a shared irq request. Signed-off-by: Manjunath Hadli manjunath.ha...@ti.com --- drivers/media/video/davinci/vpif_capture.c |2 +-

[PATCH v2 05/13] davinci: vpif display: declare contiguous region of memory handled by dma_alloc_coherent

add support to declare contiguous region of memory to be handled when requested by dma_alloc_coherent call. The user can specify the size of the buffers with an offset from the kernel image using cont_bufsize and cont_bufoffset module parameters respectively. Signed-off-by: Manjunath Hadli

[PATCH v2 06/13] davinci: vpif capture: declare contiguous region of memory handled by dma_alloc_coherent

add support to declare contiguous region of memory to be handled when requested by dma_alloc_coherent when it's asked for coherent memory for this device. The user can specify the size of the buffers with an offset from the kernel image using cont_bufsize and cont_bufoffset module parameters

[PATCH v2 08/13] davinci: vpif: add support for clipping on output data

add hardware clipping support for VPIF output data. This is needed as it is possible that the external encoder might get confused between the FF or 00 which are a part of the data and that of the SAV or EAV codes. Signed-off-by: Manjunath Hadli manjunath.ha...@ti.com ---

[PATCH v2 11/13] davinci: vpif: Add suspend/resume callbacks to vpif driver

add clock enable and disable in probe and remove functions. Probe will succeed only if the device clock is provided instead of assuming that the clock is always enabled. VPIF clock has to be dealt with during suspend and resume. Implement power management callbacks to VPIF driver to disable/enable

[PATCH v2 07/13] davinci: vpif: add support to use videobuf_iolock()

add support to use videobuf_iolock() instead of VPIF defined vpif_uservirt_to_phys API. Use videobuf_to_dma_contig API for both memory-mapped and userptr buffer allocations. Correspondingly removed vpif_uservirt_to_phys() VPIF defined API. Signed-off-by: Manjunath Hadli manjunath.ha...@ti.com ---
