The ASL syntax of this new resource looks like: PinConfig (Shared/Exclusive, PinConfigType, PinConfigValue, ResourceSource, ResourceSourceIndex, ResourceUsage, DescriptorName, Vendordata) {Pin List} PinConfigType is an integer with following accepted values: 0x00 (Default) - No configuration is applied to the pin 0x01 (Bias Pull-up) - Pin is pulled up using certain size resistor 0x02 (Bias Pull-down) - Pin is pulled down using certain size resistor 0x03 (Bias Default) - Set to default biasing 0x04 (Bias Disable) - All bias settings will be disabled 0x05 (Bias High Impedance) - Configure the pin as hi_z 0x06 (Bias Bus Hold) - Configure the pin in a weak latch state where it drives the last value on a tristate bus 0x07 (Drive Open Drain) - Configure the pin into open drain state 0x08 (Drive Open Source) - Configure the pin into open source state 0x09 (Drive Push Pull) - Configure the pin into push-pull state 0x0a (Drive Strength) - How much the pin can supply current 0x0b (Slew Rate) - Configure slew rate of the pin 0x0c (Input Debounce) - Enable input debouncer for the pin 0x0d (Input Schmitt Trigger) - Enable schmitt trigger for the pin 0x0e - 0x7f - Reserved 0x80 - 0xff - Vendor defined types The PinConfigValue depends on the type and is expressed as units suitable for that type (for example bias uses Ohms).

This resource is referenced by new PinGroupFunction() and PinGroupConfig() resources using ResourceSource and ResourceLabel fields. The PinGroup() resource looks like this: PinGroup (ResourceLabel, ResourceUsage, DescriptorName, VendorData) {Pin List} This resource should be listed in _CRS under the GPIO/pincontroller device providing these pins.

It is used with PinGroup() to configure specific mode for a set of pins exposed by a GPIO controller. The format of the resource is: PinGroupFunction (Shared/Exclusive, FunctionNumber, ResourceSource, ResourceSourceIndex, ResourceSourceLabel, ResourceUsage, DescriptorName, VendorData) The resource_source and ResourceSourceLabel fields are used to specify the PinGroup() resource referenced by PinGroupFunction(). Device (GPIO) { Name (_CRS, ResourceTemplate () { PinGroup ("group1") {2, 3} PinGroup ("group2") {4, 5} ... }) } Device (I2C) { Name (_CRS, ResourceTemplate () { PinGroupFunction (Exclusive, 6, "^GPIO", 0, "mygroup2") }) } In the above example the PinGroupFunction() references the second PinGroup() resource (using label "mygroup2" and configures pins 4 and 5 into mode 6.

The format of this new resource is: PinGroupConfig (Shared/Exclusive, PinConfigType, PinConfigValue, ResourceSource, ResourceSourceIndex, ResourceSourceLabel, ResourceUsage, DescriptorName, VendorData) The PinConfigType/PinConfigValue are the same used by PinConfig() resource. Here also the combination of ResourceSource and ResourceSourceLabel is used to specify the PinGroup() this resource refers to.
