* [media] media: soc_camera: don't clear pix->sizeimage in JPEG modeAlbert Wang2012-08-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In JPEG mode, the size of image is variable due to different JPEG compression rate. We only can get the pix->sizeimage from the user. If we clear pix->sizeimage in soc_camera_try_fmt() then we will get it from: ret = soc_mbus_image_size(xlate->host_fmt, pix->bytesperline, pix->height); if (ret < 0) return ret; pix->sizeimage = max_t(u32, pix->sizeimage, ret); In general, this sizeimage will be larger than the actul JPEG image size. But vb2 will check the buffer and size of image in __qbuf_userptr(): /* Check if the provided plane buffer is large enough */ if (planes[plane].length < q->plane_sizes[plane]) So we shouldn't clear the pix->sizeimage and also shouldn't re-calculate the pix->sizeimage in soc_mbus_image_size() in JPEG mode We also shouldn't re-calculate pix->bytesperline: ret = soc_mbus_bytes_per_line(pix->width, xlate->host_fmt); if (ret < 0) return ret; pix->bytesperline = max_t(u32, pix->bytesperline, ret); pix->bytesperline also should be set by the user or by the driver's try_fmt() implementation.

* [media] media: mx3_camera: buf_init() add buffer state checkAlex Gershgorin2012-08-15
| | | | | | | | | | | | | | | This patch checks the state of the buffer when calling .buf_init() method. This is needed for the USERPTR buffer type, because in that case .buf_init() is called every time a buffer is queued, and not only once during the preparation stage, like in the MMAP case. Without this check buffers get initialised repeatedly, which also leads to the allocation of new DMA descriptors, of which there is only a final relatively small number available. Both MMAP and USERPTR methods were successfully tested.

* [media] drivers/media/platform/mx2_emmaprp.c: use devm_kzalloc and devm_clk_getJulia Lawall2012-08-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Using devm_kzalloc simplifies the code and ensures that the use of devm_request_irq is safe. When kzalloc and kfree were used, the interrupt could be triggered after the handler's data argument had been freed. This also introduces some missing initializations of the return variable ret, and uses devm_request_and_ioremap instead of the combination of devm_request_mem_region and devm_ioremap. The problem of a free after a devm_request_irq was found using the following semantic match (http://coccinelle.lip6.fr/) // <smpl> @r exists@ expression e1,e2,x,a,b,c,d; identifier free; position p1,p2; @@ devm_request_irq@p1(e1,e2,...,x) ... when any when != e2 = a when != x = b if (...) { ... when != e2 = c when != x = d free@p2(...,x,...); ... return ...; } // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

* [media] soc-camera: Push probe-time power management to driversLaurent Pinchart2012-08-15
| | | | | | | | | | | | | | | | | Several client drivers access the hardware at probe time, for instance to read the probe chip ID. Such chips need to be powered up when being probed. soc-camera handles this by powering chips up in the soc-camera probe implementation. However, this will break with non soc-camera hosts that don't perform the same operations. Fix the problem by pushing the power up/down from the soc-camera core down to individual drivers on a needs basis.

* [media] soc-camera: Add and use soc_camera_power_[on|off]() helper functionsLaurent Pinchart2012-08-15
| | | | | | | | | | | | | Instead of forcing all soc-camera drivers to go through the mid-layer to handle power management, create soc_camera_power_[on|off]() functions that can be called from the subdev .s_power() operation to manage regulators and platform-specific power handling. This allows non soc-camera hosts to use soc-camera-aware clients.

* [media] soc-camera: Continue the power off sequence if one of the steps failsLaurent Pinchart2012-08-15
| | | | | | | | | | | | Powering off a device is a "best effort" task: failure to execute one of the steps should not prevent the next steps to be executed. For instance, an I2C communication error when putting the chip in stand-by mode should not prevent the more agressive next step of turning the chip's power supply off.

* [media] soc_camera: Don't call .s_power() during probeLaurent Pinchart2012-08-15
| | | | | | | | | | | The .s_power() call only covers the .g_mbus_fmt() operation call. Several clients required to be powered on to retrieve the current mbus format but have now been fixed. The .s_power() call is thus not needed anymore and can be removed.

* [media] rename drivers/media/video as .../platformMauro Carvalho Chehab2012-08-15
The remaining drivers are mostly platform drivers. Name the dir to reflect it. It makes sense to latter break it into a few other dirs. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
