[RFC/PATCH 1/5] HDQ/1-wire support for OMAP2430/3430

["Madhusudhan Chikkature Rajashekar" <madhu.cr@ti.com>]

Hi Tony,

I am reposting the patch after removing the defines from omap24xx.h/omap34xx.h and moved the define to devices.c as per your
suggestion.

Thanks,
Madhu
-------------------------------------------------------------------------------------

This patch adds HDQ base address defines and registers hdq as platform device.
