Subject: [PATCH v3] using mii-bitbang on different processor ports - update the booting-without-of.txt-file
Date: Mon, 10 Mar 2008 16:02:44 +0100 [thread overview]
Message-ID: <1205161364.4627.12.camel@p60365-ste> (raw)
In-Reply-To: <200803101205.16158.laurentp@cse-semaphore.com>
The patch updates the booting-without-of.txt-file.
There is a description for the case
if mdio data and clock pins are on different processor ports.
It extends the "[PATCH v3] using mii-bitbang on different processor ports".

Properties for fsl,cpm2-mdio-bitbang:
- fsl,mdio-pin : pin of port C controlling mdio data
