From fb3cfb1ff9745e0c3aab92cc141c1b353839b0ab Mon Sep 17 00:00:00 2001 From: Afzal Mohammed Date: Mon, 5 Mar 2012 16:11:01 -0800 Subject: [PATCH] ARM: OMAP2+: id: Add am33xx SoC type detection Determine SoC type, i.e. whether GP or HS Note: cpu_is_34xx() is true for am33xx also. Doing cpu_is_am33xx() check after cpu_is_34xx() will not achieve what we want due to the above reason. Hence cpu_is_am33xx() is done before cpu_is_34xx() Signed-off-by: Afzal Mohammed Signed-off-by: Vaibhav Hiremath Signed-off-by: Tony Lindgren --- arch/arm/mach-omap2/control.h | 5 +++++ arch/arm/mach-omap2/id.c | 2 ++ 2 files changed, 7 insertions(+) diff --git a/arch/arm/mach-omap2/control.h b/arch/arm/mach-omap2/control.h index 0ba68d3764bc..96c4bcc0a75c 100644 --- a/arch/arm/mach-omap2/control.h +++ b/arch/arm/mach-omap2/control.h @@ -338,6 +338,11 @@ #define AM35XX_HECC_SW_RST BIT(3) #define AM35XX_VPFE_PCLK_SW_RST BIT(4) +/* + * CONTROL AM33XX STATUS register + */ +#define AM33XX_CONTROL_STATUS 0x040 + /* * CONTROL OMAP STATUS register to identify OMAP3 features */ diff --git a/arch/arm/mach-omap2/id.c b/arch/arm/mach-omap2/id.c index 6c5826605eae..134739751107 100644 --- a/arch/arm/mach-omap2/id.c +++ b/arch/arm/mach-omap2/id.c @@ -44,6 +44,8 @@ int omap_type(void) if (cpu_is_omap24xx()) { val = omap_ctrl_readl(OMAP24XX_CONTROL_STATUS); + } else if (cpu_is_am33xx()) { + val = omap_ctrl_readl(AM33XX_CONTROL_STATUS); } else if (cpu_is_omap34xx()) { val = omap_ctrl_readl(OMAP343X_CONTROL_STATUS); } else if (cpu_is_omap44xx()) {
