commit 1a5fb99de4850cba710d91becfa2c65653048589 upstream.
Some boards with TC6393XB chip require full state restore during system
resume thanks to chip's VCC being cut off during suspend (Sharp SL-6000
tosa is one of them). Failing to do so would result in ohci Oops on
resume due to internal memory contentes being changed. Fail ohci suspend
on tc6393xb is full state restore is required.
Recommended workaround is to unbind tmio-ohci driver before suspend and
rebind it after resume.

commit 775f4b297b upstream.
We've been moving away from add_interrupt_randomness() for various
reasons: it's too expensive to do on every interrupt, and flooding the
CPU with interrupts could theoretically cause bogus floods of entropy
from a somewhat externally controllable source.
This solves both problems by limiting the actual randomness addition
to just once a second or after 64 interrupts, whicever comes first.
During that time, the interrupt cycle data is buffered up in a per-cpu
pool. Also, we make sure the the nonblocking pool used by urandom is
initialized before we start feeding the normal input pool. This
assures that /dev/urandom is returning unpredictable data as soon as
possible.
(Based on an original patch by Linus, but significantly modified by
tytso.)

When multiple channels are used for a session (Rx/Tx), all bits in the
Rx/Tx port multichannel register needs to be Set. If a bit corresponding
to any channel is missing, the channel will not be aware that the other
channel (corresponding to the missing bit) is also part of the same group.
This will create ambiguity among the channels in the same PCM group and
will lead to shifting of Phase/delay in data in those channels.

vote. During CODEC path shutdown, CODEC driver will
receive slimbus slave interrupt in time indicating
port disconnection because slimbus channel has not
be been voted off. Then, CODEC driver blindly
shutdown rest of CODEC path. This results in

The current core assumes TABLA as the only codec driver registering.
To support single binary for multiple targets its essential that
we remove this restriction and move to a generic framework
to support multiple codec. This can be done by moving all codec
specific code to dedicated codec driver and use core driver to probe
the codec based on slimbus device id and do generic setup for the
codec. This also helps to have same boards with different flavours
of codec variants.
The WCD9XXX family of codecs share the initial codec register
mapping which holds the Slimbus device id to identify the
codec existing on the target.Core driver now registers the
codec device based on this check.
