[media] soc_camera/mx3_camera.c: move to staging in preparation, for removal

2016-03-03T10:54:42+00:00

This driver is deprecated: it should become a stand-alone driver instead of using the soc-camera framework. Unless someone is willing to take this on (unlikely with such ancient hardware) it is going to be removed from the kernel soon.

[media] soc_camera/omap1: move to staging in preparation for removal

2016-03-03T10:48:34+00:00

This driver is deprecated: it needs to be converted to vb2 and it should become a stand-alone driver instead of using the soc-camera framework. Unless someone is willing to take this on (unlikely with such ancient hardware) it is going to be removed from the kernel soon.

[media] atmel-isi: Fix bad usage of IS_ERR_VALUE

2016-03-03T10:30:11+00:00

IS_ERR_VALUE() assumes that its parameter is an unsigned long. It can not be used to check if an unsigned int reflects an error. Doing so can result in the following build warning. drivers/media/platform/soc_camera/atmel-isi.c: In function "atmel_isi_probe": include/linux/err.h:21:38: warning: comparison is always false due to limited range of data type drivers/media/platform/soc_camera/atmel-isi.c:1089:6: note: in expansion of macro "IS_ERR_VALUE" If that warning is seen, the return value from platform_get_irq() is not checked for errors.

[media] pxa_camera: conversion to dmaengine

2016-03-03T10:29:17+00:00

Convert pxa_camera to dmaengine. This removes all DMA registers manipulation in favor of the more generic dmaengine API. The functional level should be the same as before. The biggest change is in the sg_split() function, which splits a videobuf-dma into several scatterlists for 3 planes captures (Y, U, V).

[media] pxa_camera: trivial move of dma irq functions

2016-03-03T10:24:26+00:00

This moves the dma irq handling functions up in the source file, so that they are available before DMA preparation functions. It prepares the conversion to DMA engine, where the descriptors are populated with these functions as callbacks.

[media] pxa_camera: move interrupt to tasklet

2016-03-03T10:23:38+00:00

In preparation for dmaengine conversion, move the camera interrupt handling into a tasklet. This won't change the global flow, as this interrupt is only used to detect the end of frame and activate DMA fifos handling.

[media] pxa_camera: fix the buffer free path

2016-03-03T10:17:12+00:00

Fix the error path where the video buffer wasn't allocated nor mapped. In this case, in the driver free path don't try to unmap memory which was not mapped in the first place. Signed-off-by: Robert Jarzmik Signed-off-by: Guennadi Liakhovetski Signed-off-by: Mauro Carvalho Chehab

[media] mx3_camera: use %pad format string for dma_ddr_t

2016-03-03T09:52:53+00:00

The mx3_camera driver prints DMA addresses using the "%x" format string, which is wrong when using a 64-bit dma_addr_t definition: media/platform/soc_camera/mx3_camera.c: In function 'mx3_cam_dma_done': media/platform/soc_camera/mx3_camera.c:149:125: error: format '%x' expects argument of type 'unsigned int', but argument 5 has type 'dma_addr_t {aka long long unsigned int}' [-Werror=format=] media/platform/soc_camera/mx3_camera.c: In function 'mx3_videobuf_queue': media/platform/soc_camera/mx3_camera.c:317:119: error: format '%x' expects argument of type 'unsigned int', but argument 5 has type 'dma_addr_t {aka long long unsigned int}' [-Werror=format=] media/platform/soc_camera/mx3_camera.c: In function 'mx3_videobuf_release': media/platform/soc_camera/mx3_camera.c:346:119: error: format '%x' expects argument of type 'unsigned int', but argument 5 has type 'dma_addr_t {aka long long unsigned int}' [-Werror=format=] This changes the code to use the special %pad format string, which always does the right thing.
