2017-07-12ACPI / irq: Fix return code of acpi_gsi_to_irq()Mark Salter1-2/+2
The function acpi_gsi_to_irq() must return 0 on success as the caller ghes_probe expects an 0 for success. This change also matches x86 implementation. This patch was submitted around 4.5 timeframe but wasn't pushed because it didn't fix a real problem. Now that RAS/GHES patches are in kernel, this fixes an error seen on a Mustang (arm64) platform: GHES: Failed to map GSI to IRQ for generic hardware error source: 2 GHES: probe of GHES.2 failed with error 81 Signed-off-by: Tuan Phan <tphan@apm.com> Signed-off-by: Loc Ho <lho@apm.com> Signed-off-by: Mark Salter <msalter@redhat.com> Acked-by: Lorenzo Pieralisi <lorenzo.pieralisi@arm.com> Signed-off-by: Rafael J.

2017-02-03ACPI: Add support for ResourceSource/IRQ domain mappingAgustin Vega-Frias1-0/+297
ACPI extended IRQ resources may contain a ResourceSource to specify an alternate interrupt controller. Introduce acpi_irq_get and use it to implement ResourceSource/IRQ domain mapping. The new API is similar to of_irq_get and allows re-initialization of a platform resource from the ACPI extended IRQ resource, and provides proper behavior for probe deferral when the domain is not yet present when called.
