Where would I look for the appropriate git kernel source tree that is 
being used for i.MX53 development feeding the distribution kernel ?

You can use Linus' tree directly.

Linus's tree does not yet include numerous imx53 drivers. 
While I can get it to boot, there is lots of hardware that does not
work. 

Freescale and others are doing imx53 driver work and most drivers are
available somewhere, though I have not found them all in the same place.

Regardless, I am just looking for an appropriate reference/starting
point. 

What would be the normal route for i.MX53 work into the kernel ?

I can pull that, start there, merge what I need and submit patches if no
one else does.

Which drivers do you need?

That's the reason development for the mainline is done here on ALKML,
with the aim to get everything into the mainline if possible.

Start with Linus' top-of-tree, discuss what you have found here on the
list (before start coding), follow the coding rules and discuss the
patches here. Don't forget to set kernel at pengutronix.de on Cc:.

You might want to have a look to Linaro, too. E.g.

http://git.linaro.org/gitweb?p=bsp/freescale/linux-linaro.git;a=shortlog;h=refs/heads/lt-3.2-imx5

If I understood correctly, from Freescale point of view, the Linaro 
Freescale landing team is responsible to mainline the Freescale work.

Best regards
