The table includes the acpi_device_id to match AMD Seattle SATA controller with following asl structure in DSDT: Device (SATA0) { Name(_HID, "AMDI0600") // Seattle AHSATA Name (_CCA, 1) // Cache-coherent controller Name (_CRS, ResourceTemplate () { Memory32Fixed (ReadWrite, 0xE0300000, 0x00010000) Interrupt (ResourceConsumer, Level, ActiveHigh, Exclusive,,,) { 387 } }) } Also, since ATA driver should not require PCI support for ATA_ACPI, this patch removes dependency in the driver/ata/Kconfig. --- drivers/ata/Kconfig | 2 +- drivers/ata/ahci_platform.c | 13 +++++++++++++ 2 files changed, 14 insertions(+), 1 deletion(-) diff --git a/drivers/ata/Kconfig b/drivers/ata/Kconfig index e1b9278..f2e6c9e 100644 --- a/drivers/ata/Kconfig +++ b/drivers/ata/Kconfig @@ -48,7 +48,7 @@ config ATA_VERBOSE_ERROR config ATA_ACPI bool "ATA ACPI Support" - depends on ACPI && PCI + depends on ACPI default y help This option adds support for ATA-related ACPI objects. diff --git a/drivers/ata/ahci_platform.c b/drivers/ata/ahci_platform.c index f61ddb9..3499bab 100644 --- a/drivers/ata/ahci_platform.c +++ b/drivers/ata/ahci_platform.c @@ -20,6 +20,9 @@ #include #include #include +#ifdef CONFIG_ATA_ACPI +#include +#endif #include "ahci.h" static const struct ata_port_info ahci_port_info = { @@ -87,6 +90,13 @@ static const struct of_device_id ahci_of_match[] = { }; MODULE_DEVICE_TABLE(of, ahci_of_match); +#ifdef CONFIG_ATA_ACPI +static const struct acpi_device_id ahci_acpi_match[] = { + { "AMDI0600", 0 }, /* AMD Seattle AHCI */ + { }, +}; +#endif + static struct platform_driver ahci_driver = { .probe = ahci_probe, .remove = ata_platform_remove_one, @@ -94,6 +104,9 @@ static struct platform_driver ahci_driver = { .name = "ahci", .owner = THIS_MODULE, .of_match_table = ahci_of_match, +#ifdef CONFIG_ATA_ACPI + .acpi_match_table = ACPI_PTR(ahci_acpi_match), +#endif .pm = &ahci_pm_ops, }, }; -- 1.9.3
