From 55035c1524b5b48ac7d267167c4895f7831897ad Mon Sep 17 00:00:00 2001 From: David Anders Date: Tue, 13 Dec 2011 10:46:44 -0800 Subject: ARM: OMAP: id: add chip id recognition for omap4430 es2.3 allow for the omap4430 es2.3 revision to be recognized in the omap4_check_revision() function. most aspects of all omap4430 es2.x versions are identical, however a number of small variations such as default pullup or pulldown resistor configurations vary between revisions. detailed information on silicon errata for omap4430 revisions can be found at http://focus.ti.com/pdfs/wtbu/swpz009D.pdf Signed-off-by: David Anders Signed-off-by: Tony Lindgren --- arch/arm/mach-omap2/id.c | 7 +++++-- 1 file changed, 5 insertions(+), 2 deletions(-) (limited to 'arch/arm/mach-omap2/id.c') diff --git a/arch/arm/mach-omap2/id.c b/arch/arm/mach-omap2/id.c index 7ab09f764600..5bb4ee18564a 100644 --- a/arch/arm/mach-omap2/id.c +++ b/arch/arm/mach-omap2/id.c @@ -393,8 +393,11 @@ static void __init omap4_check_revision(void) omap_revision = OMAP4430_REV_ES2_1; break; case 4: - default: omap_revision = OMAP4430_REV_ES2_2; + break; + case 6: + default: + omap_revision = OMAP4430_REV_ES2_3; } break; case 0xb94e: @@ -407,7 +410,7 @@ static void __init omap4_check_revision(void) break; default: /* Unknown default to latest silicon rev as default */ - omap_revision = OMAP4430_REV_ES2_2; + omap_revision = OMAP4430_REV_ES2_3; } pr_info("OMAP%04x ES%d.%d\n", omap_rev() >> 16, -- cgit v1.2.3
