Subject: spi/bcm63xx: move message control word description to register offsets
X-Git-Tag: firefly_0821_release~176^2~790^2~4^3~1
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=f13a5e8a856cda0626da316d853a71952f14b1d7;p=firefly-linux-kernel-4.4.55.git

spi/bcm63xx: move message control word description to register offsets

Make the message control word parameters part of the register offsets
array so we have them all in one struct.
