From 5a84dc5bc5d7d35d3788f4d1a9c928912c3ad41b Mon Sep 17 00:00:00 2001 From: Tero Kristo Date: Tue, 25 Sep 2012 19:33:42 +0300 Subject: [PATCH] ARM: OMAP: TWL: change the vddmin / vddmax voltages to spec As vddmin / vddmax voltages for the pmic only describe the pmic capabilities now, change the voltages to be according to spec. TWL data manuals give following values: TWL4030 (SWCS019L) : VDD1: 600mV ... 1450mV, VDD2: 600mV ... 1500mV TWL5030 (SWCS030E) : VDD1: 600mV ... 1450mV, VDD2: 600mV ... 1500mV TWL6030 (SWCS045A) : 0V ... 2100mV Signed-off-by: Tero Kristo Signed-off-by: Kevin Hilman --- arch/arm/mach-omap2/omap_twl.c | 27 ++++++++++----------------- 1 file changed, 10 insertions(+), 17 deletions(-) diff --git a/arch/arm/mach-omap2/omap_twl.c b/arch/arm/mach-omap2/omap_twl.c index dca1d662d5e0..188f21027c9a 100644 --- a/arch/arm/mach-omap2/omap_twl.c +++ b/arch/arm/mach-omap2/omap_twl.c @@ -145,8 +145,8 @@ static struct omap_voltdm_pmic omap3_mpu_pmic = { .vp_erroroffset = OMAP3_VP_CONFIG_ERROROFFSET, .vp_vstepmin = OMAP3_VP_VSTEPMIN_VSTEPMIN, .vp_vstepmax = OMAP3_VP_VSTEPMAX_VSTEPMAX, - .vddmin = OMAP3430_VP1_VLIMITTO_VDDMIN, - .vddmax = OMAP3430_VP1_VLIMITTO_VDDMAX, + .vddmin = 600000, + .vddmax = 1450000, .vp_timeout_us = OMAP3_VP_VLIMITTO_TIMEOUT_US, .i2c_slave_addr = OMAP3_SRI2C_SLAVE_ADDR, .volt_reg_addr = OMAP3_VDD_MPU_SR_CONTROL_REG, @@ -162,8 +162,8 @@ static struct omap_voltdm_pmic omap3_core_pmic = { .vp_erroroffset = OMAP3_VP_CONFIG_ERROROFFSET, .vp_vstepmin = OMAP3_VP_VSTEPMIN_VSTEPMIN, .vp_vstepmax = OMAP3_VP_VSTEPMAX_VSTEPMAX, - .vddmin = OMAP3430_VP2_VLIMITTO_VDDMIN, - .vddmax = OMAP3430_VP2_VLIMITTO_VDDMAX, + .vddmin = 600000, + .vddmax = 1450000, .vp_timeout_us = OMAP3_VP_VLIMITTO_TIMEOUT_US, .i2c_slave_addr = OMAP3_SRI2C_SLAVE_ADDR, .volt_reg_addr = OMAP3_VDD_CORE_SR_CONTROL_REG, @@ -179,8 +179,8 @@ static struct omap_voltdm_pmic omap4_mpu_pmic = { .vp_erroroffset = OMAP4_VP_CONFIG_ERROROFFSET, .vp_vstepmin = OMAP4_VP_VSTEPMIN_VSTEPMIN, .vp_vstepmax = OMAP4_VP_VSTEPMAX_VSTEPMAX, - .vddmin = OMAP4_VP_MPU_VLIMITTO_VDDMIN, - .vddmax = OMAP4_VP_MPU_VLIMITTO_VDDMAX, + .vddmin = 0, + .vddmax = 2100000, .vp_timeout_us = OMAP4_VP_VLIMITTO_TIMEOUT_US, .i2c_slave_addr = OMAP4_SRI2C_SLAVE_ADDR, .volt_reg_addr = OMAP4_VDD_MPU_SR_VOLT_REG, @@ -197,8 +197,8 @@ static struct omap_voltdm_pmic omap4_iva_pmic = { .vp_erroroffset = OMAP4_VP_CONFIG_ERROROFFSET, .vp_vstepmin = OMAP4_VP_VSTEPMIN_VSTEPMIN, .vp_vstepmax = OMAP4_VP_VSTEPMAX_VSTEPMAX, - .vddmin = OMAP4_VP_IVA_VLIMITTO_VDDMIN, - .vddmax = OMAP4_VP_IVA_VLIMITTO_VDDMAX, + .vddmin = 0, + .vddmax = 2100000, .vp_timeout_us = OMAP4_VP_VLIMITTO_TIMEOUT_US, .i2c_slave_addr = OMAP4_SRI2C_SLAVE_ADDR, .volt_reg_addr = OMAP4_VDD_IVA_SR_VOLT_REG, @@ -215,8 +215,8 @@ static struct omap_voltdm_pmic omap4_core_pmic = { .vp_erroroffset = OMAP4_VP_CONFIG_ERROROFFSET, .vp_vstepmin = OMAP4_VP_VSTEPMIN_VSTEPMIN, .vp_vstepmax = OMAP4_VP_VSTEPMAX_VSTEPMAX, - .vddmin = OMAP4_VP_CORE_VLIMITTO_VDDMIN, - .vddmax = OMAP4_VP_CORE_VLIMITTO_VDDMAX, + .vddmin = 0, + .vddmax = 2100000, .vp_timeout_us = OMAP4_VP_VLIMITTO_TIMEOUT_US, .i2c_slave_addr = OMAP4_SRI2C_SLAVE_ADDR, .volt_reg_addr = OMAP4_VDD_CORE_SR_VOLT_REG, @@ -251,13 +251,6 @@ int __init omap3_twl_init(void) if (!cpu_is_omap34xx()) return -ENODEV; - if (cpu_is_omap3630()) { - omap3_mpu_pmic.vddmin = OMAP3630_VP1_VLIMITTO_VDDMIN; - omap3_mpu_pmic.vddmax = OMAP3630_VP1_VLIMITTO_VDDMAX; - omap3_core_pmic.vddmin = OMAP3630_VP2_VLIMITTO_VDDMIN; - omap3_core_pmic.vddmax = OMAP3630_VP2_VLIMITTO_VDDMAX; - } - /* * The smartreflex bit on twl4030 specifies if the setting of voltage * is done over the I2C_SR path.
