From d41ad52040dee5043ce6b1d49a1c8864706d2bfd Mon Sep 17 00:00:00 2001 From: Paul Walmsley Date: Thu, 5 Feb 2009 20:45:25 -0700 Subject: [PATCH] [ARM] OMAP3: update ES level flags to discriminate between post-ES2 revisions Some OMAP3 chip behaviors change in ES levels after ES2. Modify the existing omap_chip flags to add options for ES3.0 and ES3.1. Add a new macro, CHIP_GE_OMAP3430ES2, to cover ES levels from ES2 onwards - a common pattern for OMAP3 features. Update all current users of the omap_chip macros to use this new macro. Also add CHIP_GE_OMAP3430ES3_1 to cover the USBTLL SAR errata case (described and fixed in the following patch) Signed-off-by: Paul Walmsley Signed-off-by: Russell King --- arch/arm/mach-omap2/clockdomains.h | 6 +++--- arch/arm/mach-omap2/id.c | 7 ++++++- arch/arm/mach-omap2/powerdomains34xx.h | 6 +++--- arch/arm/plat-omap/include/mach/cpu.h | 26 ++++++++++++++++++++------ 4 files changed, 32 insertions(+), 13 deletions(-) diff --git a/arch/arm/mach-omap2/clockdomains.h b/arch/arm/mach-omap2/clockdomains.h index d7db796403dc..281d5da19188 100644 --- a/arch/arm/mach-omap2/clockdomains.h +++ b/arch/arm/mach-omap2/clockdomains.h @@ -182,7 +182,7 @@ static struct clockdomain sgx_clkdm = { .pwrdm = { .name = "sgx_pwrdm" }, .flags = CLKDM_CAN_HWSUP_SWSUP, .clktrctrl_mask = OMAP3430ES2_CLKTRCTRL_SGX_MASK, - .omap_chip = OMAP_CHIP_INIT(CHIP_IS_OMAP3430ES2), + .omap_chip = OMAP_CHIP_INIT(CHIP_GE_OMAP3430ES2), }; /* @@ -237,7 +237,7 @@ static struct clockdomain usbhost_clkdm = { .pwrdm = { .name = "usbhost_pwrdm" }, .flags = CLKDM_CAN_HWSUP_SWSUP, .clktrctrl_mask = OMAP3430ES2_CLKTRCTRL_USBHOST_MASK, - .omap_chip = OMAP_CHIP_INIT(CHIP_IS_OMAP3430ES2), + .omap_chip = OMAP_CHIP_INIT(CHIP_GE_OMAP3430ES2), }; static struct clockdomain per_clkdm = { @@ -287,7 +287,7 @@ static struct clockdomain dpll4_clkdm = { static struct clockdomain dpll5_clkdm = { .name = "dpll5_clkdm", .pwrdm = { .name = "dpll5_pwrdm" }, - .omap_chip = OMAP_CHIP_INIT(CHIP_IS_OMAP3430ES2), + .omap_chip = OMAP_CHIP_INIT(CHIP_GE_OMAP3430ES2), }; #endif /* CONFIG_ARCH_OMAP34XX */ diff --git a/arch/arm/mach-omap2/id.c b/arch/arm/mach-omap2/id.c index b52a02fc7cd6..34b5914e0f8b 100644 --- a/arch/arm/mach-omap2/id.c +++ b/arch/arm/mach-omap2/id.c @@ -217,8 +217,13 @@ void __init omap2_check_revision(void) omap_chip.oc = CHIP_IS_OMAP3430; if (omap_rev() == OMAP3430_REV_ES1_0) omap_chip.oc |= CHIP_IS_OMAP3430ES1; - else if (omap_rev() > OMAP3430_REV_ES1_0) + else if (omap_rev() >= OMAP3430_REV_ES2_0 && + omap_rev() <= OMAP3430_REV_ES2_1) omap_chip.oc |= CHIP_IS_OMAP3430ES2; + else if (omap_rev() == OMAP3430_REV_ES3_0) + omap_chip.oc |= CHIP_IS_OMAP3430ES3_0; + else if (omap_rev() == OMAP3430_REV_ES3_1) + omap_chip.oc |= CHIP_IS_OMAP3430ES3_1; } else { pr_err("Uninitialized omap_chip, please fix!\n"); } diff --git a/arch/arm/mach-omap2/powerdomains34xx.h b/arch/arm/mach-omap2/powerdomains34xx.h index 15c346c627dd..78acfce8bbdc 100644 --- a/arch/arm/mach-omap2/powerdomains34xx.h +++ b/arch/arm/mach-omap2/powerdomains34xx.h @@ -244,7 +244,7 @@ static struct powerdomain dss_pwrdm = { static struct powerdomain sgx_pwrdm = { .name = "sgx_pwrdm", .prcm_offs = OMAP3430ES2_SGX_MOD, - .omap_chip = OMAP_CHIP_INIT(CHIP_IS_OMAP3430ES2), + .omap_chip = OMAP_CHIP_INIT(CHIP_GE_OMAP3430ES2), .wkdep_srcs = gfx_sgx_wkdeps, .sleepdep_srcs = cam_gfx_sleepdeps, /* XXX This is accurate for 3430 SGX, but what about GFX? */ @@ -312,7 +312,7 @@ static struct powerdomain neon_pwrdm = { static struct powerdomain usbhost_pwrdm = { .name = "usbhost_pwrdm", .prcm_offs = OMAP3430ES2_USBHOST_MOD, - .omap_chip = OMAP_CHIP_INIT(CHIP_IS_OMAP3430ES2), + .omap_chip = OMAP_CHIP_INIT(CHIP_GE_OMAP3430ES2), .wkdep_srcs = per_usbhost_wkdeps, .sleepdep_srcs = dss_per_usbhost_sleepdeps, .pwrsts = PWRSTS_OFF_RET_ON, @@ -354,7 +354,7 @@ static struct powerdomain dpll4_pwrdm = { static struct powerdomain dpll5_pwrdm = { .name = "dpll5_pwrdm", .prcm_offs = PLL_MOD, - .omap_chip = OMAP_CHIP_INIT(CHIP_IS_OMAP3430ES2), + .omap_chip = OMAP_CHIP_INIT(CHIP_GE_OMAP3430ES2), }; diff --git a/arch/arm/plat-omap/include/mach/cpu.h b/arch/arm/plat-omap/include/mach/cpu.h index a8e1178a9468..4166a970daa4 100644 --- a/arch/arm/plat-omap/include/mach/cpu.h +++ b/arch/arm/plat-omap/include/mach/cpu.h @@ -355,13 +355,27 @@ IS_OMAP_TYPE(3430, 0x3430) * use omap_chip_is(). * */ -#define CHIP_IS_OMAP2420 (1 << 0) -#define CHIP_IS_OMAP2430 (1 << 1) -#define CHIP_IS_OMAP3430 (1 << 2) -#define CHIP_IS_OMAP3430ES1 (1 << 3) -#define CHIP_IS_OMAP3430ES2 (1 << 4) +#define CHIP_IS_OMAP2420 (1 << 0) +#define CHIP_IS_OMAP2430 (1 << 1) +#define CHIP_IS_OMAP3430 (1 << 2) +#define CHIP_IS_OMAP3430ES1 (1 << 3) +#define CHIP_IS_OMAP3430ES2 (1 << 4) +#define CHIP_IS_OMAP3430ES3_0 (1 << 5) +#define CHIP_IS_OMAP3430ES3_1 (1 << 6) + +#define CHIP_IS_OMAP24XX (CHIP_IS_OMAP2420 | CHIP_IS_OMAP2430) + +/* + * "GE" here represents "greater than or equal to" in terms of ES + * levels.
