This is the first time I am submitting the PS3 device tree
for inclusion in the mainline kernel, so there is no breakage
or even bugfix, just new code.
I understand that Olaf would like to match what the out-of-tree
2.6.16 legacy kernel port did, but that port was never accepted
nor even recognized by the Linux community. I do not plan to
keep compatibility with that work in the mainline linux kernel.
Correctness will always take precedence over compatibility
in the mainline kernel. I will maintain what patches I can to
ease the transition from the legacy kernel to the mainline
kernel in the 'ps3-hacks' directory of my ps3-linux-patches.git
repository. I will not submit those patches for mainline
inclusion though. I'm sorry for any inconvenience.
