2008-05-29[POWERPC] Convert remaining dts-v0 files to v1David Gibson
At the moment we have a mixture of left-over version 0 and new-format version 1 files in arch/powerpc/boot/dts. This is potentially confusing to people new to the dts format attempting to figure it out. So, this patch converts all the as-yet unconverted dts v0 files and converts them to v1. They're mechanically-converted, and not hand tweaked so in some cases they're not 100% in keeping with usual v1 style, but the convertor program does have some heuristics so the discrepancies aren't too bad. I have checked that this patch produces no changes to the resulting dtb binaries.

2007-09-14[POWERPC] DTS cleanupKumar Gala
Removed the following cruft from .dts files: * 32-bit in cpu node -- doesn't exist in any spec and not used by kernel * removed built-in (chrp legacy) * Removed #interrupt-cells in places they don't need to be set * Fixed ranges on lite5200* * Removed clock-frequency from i8259 pic node, not sure where this came from * Removed big-endian from i8259 pic nodes, this was just bogus Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2007-09-07[POWERPC] Remove dtc build cruft from DTS filesJosh Boyer
The patch below removes the dtc incantation instructions from the in-kernel DTS files. It's not needed, and is prone to being out-of-date most of the time. Signed-off-by: Josh Boyer <jwboyer@linux.vnet.ibm.com> Acked-by: David Gibson <david@gibson.dropbear.id.au>
2007-06-14[POWERPC] Fix problems with device tree representation of TSI-1xx bridgesDavid Gibson
This fixes some problems with the way the some things represented in the device tree for the Holly and Taiga boards. This means changes both to the dts files, and to the code which instantiates the tsi108 ethernet platform devices based on the device tree. - First, and most importantly, the ethernet PHYs are given with an identical 'reg' property. This reg currently encodes the accessible register used to initiate mdio interaction with the PHYs, rather than a meaningful address on the parent bus (mdio in this case), which is incorrect. Instead we give the address of these registers as 'reg' in the mdio node itself, and encode the ID of each phy in their 'reg' propertyies. - Currently the platform device constructor enables a workaround in the tsi108 ethernet driver based on the compatible property of the PHY. This is incorrect, because the workaround in question is necessary due to the board's wiring of the PHY, not the model of PHY itself. This patch alters the constructor to instead enable the workaround based on a new special property in the PHY node. - The compatible properties on a number of nodes in the device tree are insufficiently precise. In particular the PHYs give only "bcm54xx", which is broken, since there are many bcm54xx PHY models, and they have differences which matter. The mdio had a compatible property of "tsi-ethernet" identical to the ethernet MAC nodes, which doesn't make sense. The ethernet, i2c, bridge and PCI nodes were given only as "tsi-*" which is somewhat inprecise, we replace with "tsi108-*" in the case of Taiga (which has a TSI108 bridge), and "tsi109-*", "tsi108-*" in the case of Holly (which has a TSI109 bridge). - We remove some "model" properties from the ethernets on Taiga board which were neither useful nor adequately precise. - On Holly we change to using a dtc label instead of a full path to reference the MPIC node, which makes the dts a little more readable.

2007-06-14[POWERPC] Don't store a command line in the Holly device treeDavid Gibson
Currently, the Holly device tree includes a bootargs property in /chosen, which gives a commandline. This is somewhat inconvenient, because it means an alternative default command line can't be given in the kernel config - the value obtained from the dts via the bootwrapper will always override CONFIG_CMDLINE. This removes the command line from the dts, and instead puts the same command line as a default in holly_defconfig.
