Subject: [RFC PATCH] ARM: OMAP3630: Add generic machine descriptor
Date: Fri, 20 Sep 2013 11:08:52 -0500	[thread overview]
Message-ID: <1379693332-10585-1-git-send-email-nm@ti.com> (raw)

Add generic machine which can handle inits for omap3630.
Currently beagle-xm would matchup with ti,omap3 which invokes
omap3430_init_early instead of omap3630_init_early

This defeats the purpose of having SoC specific init_early handlers,
example: clock nodes are not the same between 3430 and 3630.

Signed-off-by: Nishanth Menon <nm@ti.com>

An alternative approach may be to (for all SoCs):
1. define every SoC entry - ti,omap3430 ti,omap3630...
2. have a generic omap3_init which uses "if (of_machine_is_compatible("ti,omap3630"))"
to invoke the appropriate omap3xxx_init_early.
