The HD-audio CORB/RIRB communication was programmed in a way that was
documented in the reference in decades ago, which is essentially a
polling in the waiter side. It's working fine but costs CPU cycles on
some platforms that support only slow communications. Also, for some
platforms that had unreliable communications, we put longer wait time
(2 ms), which accumulate quite long time if you execute many verbs in
a shot (e.g. at the initialization or resume phase).
This patch attempts to improve the situation by introducing the
standard waitqueue in the RIRB waiter side instead of polling. The
test results on my machine show significant improvements. The time
spent for "cat /proc/asound/card*/codec#*" were changed like:
* Intel SKL + Realtek codec
before the patch:
0.00user 0.04system 0:00.10elapsed 40.0%CPU
after the patch:
0.00user 0.01system 0:00.10elapsed 10.0%CPU
* Nvidia GP107GL + Nvidia HDMI codec
before the patch:
0.00user 0.00system 0:02.76elapsed 0.0%CPU
after the patch:
0.00user 0.00system 0:00.01elapsed 17.0%CPU
So, for Intel chips, the total time is same, while the total time is
greatly reduced (from 2.76 to 0.01s) for Nvidia chips.
The only negative data here is the increase of CPU time for Nvidia,
but this is the unavoidable cost for faster wakeups, supposedly.

The current use of mode flags to us SPI_MODE_3 and
SPI_CS_HIGH is fragile: it overwrites anything already
assigned by the SPI core. Change it thusly:
- Just |= the SPI_MODE_3 so we keep other flags
- Assign ^= SPI_CS_HIGH since we might be active high
already, and that is usually the case with GPIOs used
for chip select, even if they are in practice active low.
Add a comment clarifying why ^= SPI_CS_HIGH is the right
choice here.

Gen12 can improve bandwidth efficiency by pairing up memory requests
with similar addresses. We need to program the BW_BUDDY1 and BW_BUDDY2
registers according to the memory configuration during display
initialization to take advantage of this capability.
The magic numbers we program here feel like something that could
definitely change on future platforms, so let's use a table-based
programming scheme to make this easy to extend in the future.
v2:
- Add separate table for Wa_1409767108. (Stan)
- Reorder structure reduce size by a word. Page mask can still be up
to 28 bits (even though current values are small) so we should keep
it as a u32, but just using a u8 for DRAM type instead of the actual
enum type saves space. (Lucas, Ville)
- Rename function to tgl_bw_buddy_init() to be more precise about what
it does. (Lucas)

On non-samefs overlay without xino, non pure upper inodes should use a
pseudo_dev assigned to each unique lower fs and pure upper inodes use the
real upper st_dev.
It is fine for an overlay pure upper inode to use the same st_dev;st_ino
values as the real upper inode, because the content of those two different
filesystem objects is always the same.
In this case, however:
- two filesystems, A and B
- upper layer is on A
- lower layer 1 is also on A
- lower layer 2 is on B
Non pure upper overlay inode, whose origin is in layer 1 will have the same
st_dev;st_ino values as the real lower inode. This may result with a false
positive results of 'diff' between the real lower and copied up overlay
inode.
Fix this by using the upper st_dev;st_ino values in this case. This breaks
the property of constant st_dev;st_ino across copy up of this case. This
breakage will be fixed by a later patch.
