From 4dea547fef1ba23f9d23f5e7f5218187a7dcf1b3 Mon Sep 17 00:00:00 2001 From: Grant Likely Date: Sat, 25 Apr 2009 12:52:46 +0000 Subject: phylib: rework to prepare for OF registration of PHYs This patch makes changes in preparation for supporting open firmware device tree descriptions of MDIO busses. Changes include: - Cleanup handling of phy_map[] entries; they are already NULLed when registering and so don't need to be re-cleared, and it is good practice to clear them out when unregistering. - Split phy_device registration out into a new function so that the OF helpers can do two stage registration (separate allocation and registration steps).

This patch is useful for OF device tree descriptions of phy devices where the driver doesn't need or know what the bus_id value in order to get a phy_device pointer.

Miller" Date: Tue, 26 May 2009 21:16:25 -0700 Subject: phy: Eliminate references to BUS_ID_SIZE. Just use the constant 20 to keep things working. If someone is so motivated, this can be converted over to dynamic strings. I tried and it's a lot of work. But for now this is good enough. Signed-off-by: David S.
