From ef557d76dfbdf74c240f76be15fa90d62f1ae61f Mon Sep 17 00:00:00 2001 From: Andrzej Zaborowski Date: Wed, 6 Dec 2006 17:13:48 -0800 Subject: [PATCH] ARM: OMAP: correct misc 15xx and non-15xx platform code Disable accesses to SOFT_REQ_REG2 and ULPD_SOFT_DISABLE_REQ_REG registers for 15xx processors that don't have these registers. Enable level 2 interrupt handler for processors that identify as OMAP 15xx (e.g 310) and not 1510 specifically. Also fix the following compiler warning (only visible with CONFIG_OMAP_RESET_CLOCKS): arch/arm/mach-omap1/clock.c: In function 'omap1_clk_disable_unused': arch/arm/mach-omap1/clock.c:634: warning: 'return' with a value, in function returning void Signed-off-by: Andrzej Zaborowski Signed-off-by: Tony Lindgren --- arch/arm/mach-omap1/clock.c | 5 +++-- arch/arm/mach-omap1/irq.c | 2 +- arch/arm/mach-omap1/pm.c | 6 ++++-- 3 files changed, 8 insertions(+), 5 deletions(-) diff --git a/arch/arm/mach-omap1/clock.c b/arch/arm/mach-omap1/clock.c index 638490e62d5f..f8e12946862c 100644 --- a/arch/arm/mach-omap1/clock.c +++ b/arch/arm/mach-omap1/clock.c @@ -496,7 +496,7 @@ static int omap1_clk_enable_generic(struct clk *clk) } } - return 0; + return; } static void omap1_clk_disable_generic(struct clk *clk) @@ -654,7 +654,8 @@ int __init omap1_clk_init(void) /* USB_REQ_EN will be disabled later if necessary (usb_dc_ck) */ reg = omap_readw(SOFT_REQ_REG) & (1 << 4); omap_writew(reg, SOFT_REQ_REG); - omap_writew(0, SOFT_REQ_REG2); + if (!cpu_is_omap15xx()) + omap_writew(0, SOFT_REQ_REG2); clk_init(&omap1_clk_functions); diff --git a/arch/arm/mach-omap1/irq.c b/arch/arm/mach-omap1/irq.c index 6383a12ad970..410d3e78dd0f 100644 --- a/arch/arm/mach-omap1/irq.c +++ b/arch/arm/mach-omap1/irq.c @@ -238,7 +238,7 @@ void __init omap_init_irq(void) if (cpu_is_omap730()) omap_unmask_irq(INT_730_IH2_IRQ); - else if (cpu_is_omap1510()) + else if (cpu_is_omap15xx()) omap_unmask_irq(INT_1510_IH2_IRQ); else if (cpu_is_omap16xx()) omap_unmask_irq(INT_1610_IH2_IRQ); diff --git a/arch/arm/mach-omap1/pm.c b/arch/arm/mach-omap1/pm.c index 4834758d340c..8ff232034871 100644 --- a/arch/arm/mach-omap1/pm.c +++ b/arch/arm/mach-omap1/pm.c @@ -256,7 +256,8 @@ void omap_pm_suspend(void) tps65010_set_led(LED1, OFF); } - omap_writew(0xffff, ULPD_SOFT_DISABLE_REQ_REG); + if (!cpu_is_omap15xx()) + omap_writew(0xffff, ULPD_SOFT_DISABLE_REQ_REG); /* * Step 1: turn off interrupts (FIXME: NOTE: already disabled) @@ -434,7 +435,8 @@ void omap_pm_suspend(void) MPUI1610_RESTORE(OMAP_IH2_3_MIR); } - omap_writew(0, ULPD_SOFT_DISABLE_REQ_REG); + if (!cpu_is_omap15xx()) + omap_writew(0, ULPD_SOFT_DISABLE_REQ_REG); /* * Reenable interrupts -- 2.20.1
