From eb77b6a78ac7f63985a3f592baf80ff33d213c48 Mon Sep 17 00:00:00 2001 From: Afzal Mohammed Date: Fri, 5 Oct 2012 11:39:54 +0530 Subject: [PATCH] ARM: OMAP2+: onenand: connected soc info in pdata onenand driver needs to know whether soc is falling under 34xx family to properly handle onenand. But driver is not supposed to do cpu_is_* check, hence educate platform data with this information. Driver can make use of it to avoid cpu_is_* check.
