From 1d3bb996481e116f5f2b127cbd29b83365d2cf62 Mon Sep 17 00:00:00 2001 From: David Gibson Date: Thu, 23 Aug 2007 13:56:01 +1000 Subject: Device tree aware EMAC driver Based on BenH's earlier work, this is a new version of the EMAC driver for the built-in ethernet found on PowerPC 4xx embedded CPUs. The same ASIC is also found in the Axon bridge chip. This new version is designed to work in the arch/powerpc tree, using the device tree to probe the device, rather than the old and ugly arch/ppc OCP layer. This driver is designed to sit alongside the old driver (that lies in drivers/net/ibm_emac and this one in drivers/net/ibm_newemac). The old driver is left in place to support arch/ppc until arch/ppc itself reaches its final demise (not too long now, with luck). This driver still has a number of things that could do with cleaning up, but I think they can be fixed up after merging. Specifically: - Should be adjusted to properly use the dma mapping API. Axon needs this. - Probe logic needs reworking, in conjuction with the general probing code for of_platform devices. The dependencies here between EMAC, MAL, ZMII etc. make this complicated. At present, it usually works, because we initialize and register the sub-drivers before the EMAC driver itself, and (being in driver code) runs after the devices themselves have been instantiated from the device tree.
