Date: Thu,  9 Jun 2016 23:37:28 +0300	[thread overview]
Message-ID: <1465504648-15038-1-git-send-email-aaro.koskinen@iki.fi> (raw)

Document cavium-pip rx-delay/tx-delay properties. Currently the board
specific values need to be hardcoded in the platform code, which we
want to avoid when moving to DT-only booting.
