For both BT.656 and BT.1120 video, the pixel format
used by VPIF is Y/CbCr 4:2:2 in semi-planar format
(Luma in one plane and Chroma in another). This
corresponds to NV16 pixel format.
This is documented in section 36.2.3 of OMAP-L138
Technical Reference Manual, SPRUH77A.
The VPIF driver incorrectly sets the default format
to V4L2_PIX_FMT_YUV422P. Fix it.

====================
Introduce bpf ID
This patch series:
1) Introduce ID for both bpf_prog and bpf_map.
2) Add bpf commands to iterate the prog IDs and map
IDs of the system.
3) Add bpf commands to get a prog/map fd from an ID
4) Add bpf command to get prog/map info from a fd.
The prog/map info is a jump start in this patchset
and it is not meant to be a complete list. They can
be extended in the future patches.
v3:
- I suspect v2 may not have applied cleanly.
In particular, patch 1 has conflict with a recent
change in struct bpf_prog_aux introduced at a similar time frame:
8726679a0f ("bpf: teach verifier to track stack depth")
v3 should have fixed it.
v2:
Compiler warning fixes:
- Remove lockdep_is_held() usage. Add comment
to explain the lock situation instead.
- Add static for idr related variables
- Add __user to the uattr param in bpf_prog_get_info_by_fd()
and bpf_map_get_info_by_fd().

A single BPF_OBJ_GET_INFO_BY_FD cmd is used to obtain the info
for both bpf_prog and bpf_map. The kernel can figure out the
fd is associated with a bpf_prog or bpf_map.
The suggested struct bpf_prog_info and struct bpf_map_info are
not meant to be a complete list and it is not the goal of this patch.
New fields can be added in the future patch.
The focus of this patch is to create the interface,
BPF_OBJ_GET_INFO_BY_FD cmd for exposing the bpf_prog's and
bpf_map's info.
The obj's info, which will be extended (and get bigger) over time, is
separated from the bpf_attr to avoid bloating the bpf_attr.

In the error path of bpf_map_inc_not_zero(), it may have to

This patch generates an unique ID for each BPF_PROG_LOAD-ed prog.
It is worth to note that each BPF_PROG_LOAD-ed prog will have
a different ID even they have the same bpf instructions.
The ID is generated by the existing idr_alloc_cyclic().
The ID is ranged from [1, INT_MAX). It is allocated in cyclic manner,
so an ID will get reused every 2 billion BPF_PROG_LOAD.
The bpf_prog_alloc_id() is done after bpf_prog_select_runtime()
because the jit process may have allocated a new prog. Hence,
we need to ensure the value of pointer 'prog' will not be changed
any more before storing the prog to the prog_idr.
After bpf_prog_select_runtime(), the prog is read-only. Hence,
the id is stored in 'struct bpf_prog_aux'.

In commit 9a075265c6 ("ASoC: Intel: sst: Remove unused function
sst_restore_shim64()"), we deleted the sst_restore_shim64() since it
was never used. ...but a quick look at the code shows that we should
also be able to remove the sst_save_shim64() function and the
structure members we were storing data in.
Once we delete sst_save_shim64() there are no longer any users of the
'sst_shim_regs64' structure. That means we can delete it completely
and also avoid allocating memory for it. This saves a whopping 136
bytes of devm allocated memory. We also get the nice benefit of
avoiding an error path in the init code.
Note that the saving code that we're removing (and the comments
talking about how important it is to do the save) has been around
since commit 336cfbb05e ("ASoC: Intel: mrfld- add ACPI module").

afterwards. Since LZO support itself has its own size, it currently is
rather a deoptimization.
So make it optional by introducing a symbol that can be selected by
drivers wanting to make use of it.
Saves e.g. ~46 kB on MIPS (size of LZO support + regcache LZO code).
