dma-mapping: use unsigned long for dma_attrs

2016-08-04T12:50:07+00:00

The dma-mapping core and the implementations do not change the DMA
attributes passed by pointer.  Thus the pointer can point to const data.
However the attributes do not have to be a bitfield.  Instead unsigned
long will do fine:

1. This is just simpler.  Both in terms of reading the code and setting
   attributes.  Instead of initializing local attributes on the stack
   and passing pointer to it to dma_set_attr(), just set the bits.

2. It brings safeness and checking for const correctness because the
   attributes are passed by value.

[media] vivid: don't handle CEC_MSG_SET_STREAM_PATH

2016-07-28T23:15:23+00:00

vivid shouldn't process the CEC_MSG_SET_STREAM_PATH message: this will confuse
userspace follower code because it isn't aware of the state change of becoming
an active source.

[media] mtk-vcodec: fix default OUTPUT buffer size

2016-07-15T16:19:35+00:00

When calculate OUTPUT buffer size in vidioc_try_fmt, it will
add more size hw need in each plane.
But in mtk_vcodec_enc_set_default_params, it do not add
same size in each plane.
This makes v4l2-compliance test fail.

[media] mtk-vcodec: fix more type mismatches

2016-07-15T15:37:17+00:00

The newly added mtk-vcodec driver produces a number of warnings in an
ARM allmodconfig build, mainly since it assumes that dma_addr_t is
32-bit wide:

mtk-vcodec/venc/venc_vp8_if.c: In function 'vp8_enc_alloc_work_buf':
mtk-vcodec/venc/venc_vp8_if.c:212:191: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast]
mtk-vcodec/venc/venc_h264_if.c: In function 'h264_enc_alloc_work_buf':
mtk-vcodec/venc/venc_h264_if.c:297:190: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast]

This rearranges the format strings and type casts to what they should
have been in order to avoid the warnings. e0f80d8d62f5 ("[media]
mtk-vcodec: fix two compiler warnings") fixed some of the problems that
were introduced at the same time, but missed two others.
