I accidentally removed some mux code for omap4 that I thought was 

dead code as omap4 has been booting with device tree only since
 v3.10. Turns out I also removed some display related mux code,
 so let's revert that except for the dead code parts.

Invalidation is removing an entry from the cache without writing it
back. Cache blocks can be invalidated via the invalidate_cblocks
message, which takes an arbitrary number of cblock ranges. Each cblock
must be expressed as a decimal value, in the future a variant message
that takes cblock ranges expressed in hexidecimal may be needed to
better support efficient invalidation of larger caches. The cache must
be in passthrough mode when invalidate_cblocks is used.

@ -123,6 +123,16 @@ Transmission process is similar to capture as shown below.
[shutdown] close() --------> destruction of the transmission socket and
deallocation of all associated resources.
Socket creation and destruction is also straight forward, and is done
the same way as in capturing described in the previous paragraph:
int fd = socket(PF_PACKET, mode, 0);
The protocol can optionally be 0 in case we only want to transmit
via this socket, which avoids an expensive call to packet_rcv().
In this case, you also need to bind(2) the TX_RING with sll_protocol = 0
set. Otherwise, htons(ETH_P_ALL) or any other protocol, for example.
Binding the socket to your network interface is mandatory (with zero copy) to
know the header size of frames used in the circular buffer.
