From 7abc8cabad977aeccbbb6e6b2026e68ab8e32c65 Mon Sep 17 00:00:00 2001 From: Guenter Roeck Date: Mon, 17 Feb 2020 12:48:12 -0800 Subject: [PATCH] arm: allwinner: Wire up USB ports Instantiate EHCI and OHCI controllers on Allwinner A10. OHCI ports are modeled as companions of the respective EHCI ports. With this patch applied, USB controllers are discovered and instantiated when booting the cubieboard machine with a recent Linux kernel. ehci-platform 1c14000.usb: EHCI Host Controller ehci-platform 1c14000.usb: new USB bus registered, assigned bus number 1 ehci-platform 1c14000.usb: irq 26, io mem 0x01c14000 ehci-platform 1c14000.usb: USB 2.0 started, EHCI 1.00 ehci-platform 1c1c000.usb: EHCI Host Controller ehci-platform 1c1c000.usb: new USB bus registered, assigned bus number 2 ehci-platform 1c1c000.usb: irq 31, io mem 0x01c1c000 ehci-platform 1c1c000.usb: USB 2.0 started, EHCI 1.00 ohci-platform 1c14400.usb: Generic Platform OHCI controller ohci-platform 1c14400.usb: new USB bus registered, assigned bus number 3 ohci-platform 1c14400.usb: irq 27, io mem 0x01c14400 ohci-platform 1c1c400.usb: Generic Platform OHCI controller ohci-platform 1c1c400.usb: new USB bus registered, assigned bus number 4 ohci-platform 1c1c400.usb: irq 32, io mem 0x01c1c400 usb 2-1: new high-speed USB device number 2 using ehci-platform usb-storage 2-1:1.0: USB Mass Storage device detected scsi host1: usb-storage 2-1:1.0 usb 3-1: new full-speed USB device number 2 using ohci-platform input: QEMU QEMU USB Mouse as /devices/platform/soc/1c14400.usb/usb3/3-1/3-1:1.0/0003:0627:0001.0001/input/input0 Reviewed-by: Gerd Hoffmann Signed-off-by: Guenter Roeck Tested-by: Niek Linnenbank Message-id: 20200217204812.9857-4-linux@roeck-us.net Signed-off-by: Peter Maydell --- hw/arm/allwinner-a10.c | 43 ++++++++++++++++++++++++++++++++++ include/hw/arm/allwinner-a10.h | 6 +++++ 2 files changed, 49 insertions(+) diff --git a/hw/arm/allwinner-a10.c b/hw/arm/allwinner-a10.c index 1cde165611..2ae9c15311 100644 --- a/hw/arm/allwinner-a10.c +++ b/hw/arm/allwinner-a10.c @@ -24,11 +24,15 @@ #include "hw/arm/allwinner-a10.h" #include "hw/misc/unimp.h" #include "sysemu/sysemu.h" +#include "hw/boards.h" +#include "hw/usb/hcd-ohci.h" #define AW_A10_PIC_REG_BASE 0x01c20400 #define AW_A10_PIT_REG_BASE 0x01c20c00 #define AW_A10_UART0_REG_BASE 0x01c28000 #define AW_A10_EMAC_BASE 0x01c0b000 +#define AW_A10_EHCI_BASE 0x01c14000 +#define AW_A10_OHCI_BASE 0x01c14400 #define AW_A10_SATA_BASE 0x01c18000 static void aw_a10_init(Object *obj) @@ -49,6 +53,17 @@ static void aw_a10_init(Object *obj) sysbus_init_child_obj(obj, "sata", &s->sata, sizeof(s->sata), TYPE_ALLWINNER_AHCI); + + if (machine_usb(current_machine)) { + int i; + + for (i = 0; i < AW_A10_NUM_USB; i++) { + sysbus_init_child_obj(obj, "ehci[*]", OBJECT(&s->ehci[i]), + sizeof(s->ehci[i]), TYPE_PLATFORM_EHCI); + sysbus_init_child_obj(obj, "ohci[*]", OBJECT(&s->ohci[i]), + sizeof(s->ohci[i]), TYPE_SYSBUS_OHCI); + } + } } static void aw_a10_realize(DeviceState *dev, Error **errp) @@ -121,6 +136,34 @@ static void aw_a10_realize(DeviceState *dev, Error **errp) serial_mm_init(get_system_memory(), AW_A10_UART0_REG_BASE, 2, qdev_get_gpio_in(dev, 1), 115200, serial_hd(0), DEVICE_NATIVE_ENDIAN); + + if (machine_usb(current_machine)) { + int i; + + for (i = 0; i < AW_A10_NUM_USB; i++) { + char bus[16]; + + sprintf(bus, "usb-bus.%d", i); + + object_property_set_bool(OBJECT(&s->ehci[i]), true, + "companion-enable", &error_fatal); + object_property_set_bool(OBJECT(&s->ehci[i]), true, "realized", + &error_fatal); + sysbus_mmio_map(SYS_BUS_DEVICE(&s->ehci[i]), 0, + AW_A10_EHCI_BASE + i * 0x8000); + sysbus_connect_irq(SYS_BUS_DEVICE(&s->ehci[i]), 0, + qdev_get_gpio_in(dev, 39 + i)); + + object_property_set_str(OBJECT(&s->ohci[i]), bus, "masterbus", + &error_fatal); + object_property_set_bool(OBJECT(&s->ohci[i]), true, "realized", + &error_fatal); + sysbus_mmio_map(SYS_BUS_DEVICE(&s->ohci[i]), 0, + AW_A10_OHCI_BASE + i * 0x8000); + sysbus_connect_irq(SYS_BUS_DEVICE(&s->ohci[i]), 0, + qdev_get_gpio_in(dev, 64 + i)); + } + } } static void aw_a10_class_init(ObjectClass *oc, void *data) diff --git a/include/hw/arm/allwinner-a10.h b/include/hw/arm/allwinner-a10.h index 40d0b1d9c0..8af724548f 100644 --- a/include/hw/arm/allwinner-a10.h +++ b/include/hw/arm/allwinner-a10.h @@ -8,12 +8,16 @@ #include "hw/intc/allwinner-a10-pic.h" #include "hw/net/allwinner_emac.h" #include "hw/ide/ahci.h" +#include "hw/usb/hcd-ohci.h" +#include "hw/usb/hcd-ehci.h" #include "target/arm/cpu.h" #define AW_A10_SDRAM_BASE 0x40000000 +#define AW_A10_NUM_USB 2 + #define TYPE_AW_A10 "allwinner-a10" #define AW_A10(obj) OBJECT_CHECK(AwA10State, (obj), TYPE_AW_A10) @@ -28,6 +32,8 @@ typedef struct AwA10State { AwEmacState emac; AllwinnerAHCIState sata; MemoryRegion sram_a; + EHCISysBusState ehci[AW_A10_NUM_USB]; + OHCISysBusState ohci[AW_A10_NUM_USB]; } AwA10State; #endif
