2014-12-02[media] staging/media: fix querycapHans Verkuil3-9/+9
Querycap shouldn't set the version field (the core does that for you), but it should set the device_caps field. Signed-off-by: Hans Verkuil <[email protected]> Acked-by: Lad, Prabhakar <[email protected]> Signed-off-by: Mauro Carvalho Chehab <[email protected]>

2014-12-02[media] vivid: add new colorspacesHans Verkuil3-18/+36
Add AdobeRGB and BT.2020 support. The colorspace control now orders the colorspaces according to how often they are used. So rarely used colorspaces are moved to the end. This makes it more logical when testing colorspace support. Signed-off-by: Hans Verkuil <[email protected]> Signed-off-by: Mauro Carvalho Chehab <[email protected]>
2014-12-02[media] vivid-tpg: improve colorspace supportHans Verkuil2-107/+258

2014-12-02[media] vivid-tpg-colors: add AdobeRGB and BT.2020 supportHans Verkuil2-43/+665
This extends the precalculated tpg_csc_colors matrix with AdobeRGB and BT.2020 colorspace support. It also adds two precalculated tables that convert between linear RGB and non-linear Rec.709 R'G'B' values, i.e. the Rec. 709 transfer function. This is needed to efficiently handle the BT.2020 Constant Luminance Yc'CbcCrc encoding and decoding.

Amlogic Meson SoCs include a infrared remote control receiver that can operate in two modes: "NEC" mode in which the hardware decodes frames using the NEC IR protocol, and "general" mode in which the receiver simply reports the duration of pulses and spaces for software decoding. This is a driver for the IR receiver that implements software decoding of received frames.

2014-11-25[media] vb2: use dma_map_sg_attrs to prevent unnecessary syncHans Verkuil2-10/+47
By default dma_map_sg syncs the mapped buffer to the device. But buf_prepare expects a buffer syncs for the cpu and the buffer will be synced to the device in the prepare memop. The reverse is true for dma_unmap_sg, buf_finish and the finish memop. To prevent unnecessary syncs we ask dma_(un)map_sg to skip the sync.

2014-11-25[media] vb2-dma-sg: move dma_(un)map_sg hereHans Verkuil14-130/+64
This moves dma_(un)map_sg to the get_userptr/put_userptr and alloc/put memops of videobuf2-dma-sg.c and adds dma_sync_sg_for_device/cpu to the prepare/finish memops. Now that vb2-dma-sg will sync the buffers for you in the prepare/finish memops we can drop that from the drivers that use dma-sg. For the solo6x10 driver that was a bit more involved because it needs to copy JPEG or MPEG headers to the buffer before returning it to userspace, and that cannot be done in the old place since the buffer there is still setup for DMA access, not for CPU access. However, the buf_finish op is the ideal place to do this. By the time buf_finish is called the buffer is available for CPU access, so copying to the buffer is fine.
