The Timer controller include 8 sets of 32-bit decrement counters. The base address of TIMER0 to TIMER7 as following. Base Address of Timer 0 = 0x12C1_0000 Base Address of Timer 1 = 0x12C1_0040 Base Address of Timer 2 = 0x12C1_0080 Base Address of Timer 3 = 0x12C1_00C0 Base Address of Timer 4 = 0x12C1_0100 Base Address of Timer 5 = 0x12C1_0140 Base Address of Timer 6 = 0x12C1_0180 Base Address of Timer 7 = 0x12C1_01C0 The interrupt of TIMER0 to TIMER7 as following. GICINT16 = TIMER 0 interrupt GICINT17 = TIMER 1 interrupt GICINT18 = TIMER 2 interrupt GICINT19 = TIMER 3 interrupt GICINT20 = TIMER 4 interrupt GICINT21 = TIMER 5 interrupt GICINT22 = TIMER 6 interrupt GICINT23 = TIMER 7 interrupt Signed-off-by: Jamin Lin Reviewed-by: Cédric Le Goater Link: https://lore.kernel.org/r/20250113064455.1660564-4-jamin_lin@aspeedtech.com Signed-off-by: Cédric Le Goater --- diff --git a/hw/arm/aspeed_ast27x0.c b/hw/arm/aspeed_ast27x0.c index fee3755837..4114e15ddd 100644 --- a/hw/arm/aspeed_ast27x0.c +++ b/hw/arm/aspeed_ast27x0.c @@ -66,6 +66,7 @@ static const hwaddr aspeed_soc_ast2700_memmap[] = { [ASPEED_DEV_GPIO] = 0x14C0B000, [ASPEED_DEV_RTC] = 0x12C0F000, [ASPEED_DEV_SDHCI] = 0x14080000, + [ASPEED_DEV_TIMER1] = 0x12C10000, }; #define AST2700_MAX_IRQ 256 @@ -397,6 +398,9 @@ static void aspeed_soc_ast2700_init(Object *obj) object_initialize_child(obj, "emmc-controller.sdhci", &s->emmc.slots[0], TYPE_SYSBUS_SDHCI); + + snprintf(typename, sizeof(typename), "aspeed.timer-%s", socname); + object_initialize_child(obj, "timerctrl", &s->timerctrl, typename); } /* @@ -716,6 +720,19 @@ static void aspeed_soc_ast2700_realize(DeviceState *dev, Error **errp) sysbus_connect_irq(SYS_BUS_DEVICE(&s->emmc), 0, aspeed_soc_get_irq(s, ASPEED_DEV_EMMC)); + /* Timer */ + object_property_set_link(OBJECT(&s->timerctrl), "scu", OBJECT(&s->scu), + &error_abort); + if (!sysbus_realize(SYS_BUS_DEVICE(&s->timerctrl), errp)) { + return; + } + aspeed_mmio_map(s, SYS_BUS_DEVICE(&s->timerctrl), 0, + sc->memmap[ASPEED_DEV_TIMER1]); + for (i = 0; i < ASPEED_TIMER_NR_TIMERS; i++) { + irq = aspeed_soc_get_irq(s, ASPEED_DEV_TIMER1 + i); + sysbus_connect_irq(SYS_BUS_DEVICE(&s->timerctrl), i, irq); + } + create_unimplemented_device("ast2700.dpmcu", 0x11000000, 0x40000); create_unimplemented_device("ast2700.iomem0", 0x12000000, 0x01000000); create_unimplemented_device("ast2700.iomem1", 0x14000000, 0x01000000);
