From 7e5e8c94a9dd6654285aff96e0ff45a353ed79fa Mon Sep 17 00:00:00 2001 From: Fabio Estevam Date: Thu, 26 Dec 2013 14:51:32 -0200 Subject: [PATCH] mx6: soc: Set the VDDSOC at 1.175 V mx6 datasheet specifies that the minimum VDDSOC at 792 MHz is 1.15 V. Add a 25 mV margin and set it to 1.175V. This also matches the VDDSOC voltages for 792MHz operation that the kernel configures: http://git.freescale.com/git/cgit.cgi/imx/linux-2.6-imx.git/tree/arch/arm/mach-mx6/cpu_op-mx6.c?h=imx_3.0.35_4.1.0 Signed-off-by: Fabio Estevam --- arch/arm/cpu/armv7/mx6/soc.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/arch/arm/cpu/armv7/mx6/soc.c b/arch/arm/cpu/armv7/mx6/soc.c index 486b870312..3e095aab84 100644 --- a/arch/arm/cpu/armv7/mx6/soc.c +++ b/arch/arm/cpu/armv7/mx6/soc.c @@ -151,7 +151,7 @@ int arch_cpu_init(void) { init_aips(); - set_vddsoc(1200); /* Set VDDSOC to 1.2V */ + set_vddsoc(1175); /* Set VDDSOC to 1.175V */ imx_set_wdog_powerdown(false); /* Disable PDE bit of WMCR register */ -- 2.30.2
