It is nicer to have enable/disable functions instead of set(bool enable)
style function.

Split tc_main_link_stream into tc_stream_enable and tc_stream_disable.

The driver currently sets the video stream registers in
tc_main_link_setup. One should be able to establish the DP link without
any video stream, so a more logical place is to configure the stream in
the tc_main_link_stream. So move them there.

The driver sets up AUX link at probe time, but, for some reason, also
sets the main link's number of lanes using tc->link.base.num_lanes. This
is not needed nor correct, as the number of lanes has not been decided
yet. The number of lanes will be set later during main link setup.

Modify aux_link_setup so that it does not use tc->link, and thus makes
aux setup independent of the link probing.

DP always uses ANSI 8B10B encoding. Some monitors (old?) may not have
the ANSI 8B10B bit set in DPCD, even if it should always be set.

The tc358767 driver currently respects that flag, and turns the encoding
off if the monitor does not have the bit set, which then results in the
monitor not working.

This patch makes the driver to always use ANSI 8B10B encoding, and drops
the 'coding8b10b' field which is no longer used.

Drop use of the deprecated drmP.h header file.

While touching the list of include files:
- Divide include files in blocks of linux/* drm/* etc.
- Sort individual blocks of include files
- Remove duplicated header file

v2:
- Be consistent in the order of the include blocks (Laurent)

Fixes: eb9d1bf0: "random: only read from /dev/random after its pool has received 128 bits"
Reported-by: Nkernel test robot <lkp@intel.com>
Signed-off-by: NTheodore Ts'o <tytso@mit.edu>

Starting with GCC 9, -Warray-bounds detects cases when memset is called
starting on a member of a struct but the size to be cleared ends up
writing over further members.

Such a call happens in the trace code to clear, at once, all members
after and including `seq` on struct trace_iterator:

    In function 'memset',
        inlined from 'ftrace_dump' at kernel/trace/trace.c:8914:3:
    ./include/linux/string.h:344:9: warning: '__builtin_memset' offset
    [8505, 8560] from the object at 'iter' is out of the bounds of
    referenced subobject 'seq' with type 'struct trace_seq' at offset
    4368 [-Warray-bounds]
      344 |  return __builtin_memset(p, c, size);
          |         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~

In order to avoid GCC complaining about it, we compute the address
ourselves by adding the offsetof distance instead of referring
directly to the member.

Since there are two places doing this clear (trace.c and trace_kdb.c),
take the chance to move the workaround into a single place in
the internal header.

it can compatible with techstar ts8550b bsp timings this patch swap
