ACPI / platform: Add support for build-in properties

2016-11-09T23:30:29Z

We have a couple of drivers, acpi_apd.c and acpi_lpss.c, that need to pass extra build-in properties to the devices they create. Previously the drivers added those properties to the struct device which is member of the struct acpi_device, but that does not work. Those properties need to be assigned to the struct device of the platform device instead in order for them to become available to the drivers. To fix this, this patch changes acpi_create_platform_device function to take struct property_entry pointer as parameter.

ACPI/PCI: pci_link: penalize SCI correctly

2016-10-24T12:18:14Z

Ondrej reported that IRQs stopped working in v4.7 on several platforms. A typical scenario, from Ondrej's VT82C694X/694X, is: ACPI: Using PIC for interrupt routing ACPI: PCI Interrupt Link [LNKA] (IRQs 1 3 4 5 6 7 10 *11 12 14 15) ACPI: No IRQ available for PCI Interrupt Link [LNKA] 8139too 0000:00:0f.0: PCI INT A: no GSI We're using PIC routing, so acpi_irq_balance == 0, and LNKA is already active at IRQ 11. In that case, acpi_pci_link_allocate() only tries to use the active IRQ (IRQ 11) which also happens to be the SCI. We should penalize the SCI by PIRQ_PENALTY_PCI_USING, but irq_get_trigger_type(11) returns something other than IRQ_TYPE_LEVEL_LOW, so we penalize it by PIRQ_PENALTY_ISA_ALWAYS instead, which makes acpi_pci_link_allocate() assume the IRQ isn't available and give up. Add acpi_penalize_sci_irq() so platforms can tell us the SCI IRQ, trigger, and polarity directly and we don't have to depend on irq_get_trigger_type().

ACPI / property: Allow holes in reference properties

2016-10-11T20:44:00Z

DT allows holes or empty phandles for references. This is used for example in SPI subsystem where some chip selects are native and others are regular GPIOs. In ACPI _DSD we currently do not support this but instead the preceding reference consumes all following integer arguments. For example we would like to support something like the below ASL fragment for SPI: Package () { "cs-gpios", Package () { ^GPIO, 19, 0, 0, // GPIO CS0 0, // Native CS ^GPIO, 20, 0, 0, // GPIO CS1 } } The zero in the middle means "no entry" or NULL reference. To support this we change acpi_data_get_property_reference() to take firmware node and num_args as argument and rename it to __acpi_node_get_property_reference(). The function returns -ENOENT if the given index resolves to "no entry" reference and -ENODATA when there are no more entries in the property. We then add static inline wrapper acpi_node_get_property_reference() that passes MAX_ACPI_REFERENCE_ARGS as num_args to support the existing behaviour which some drivers have been relying on.
