2020-08-18soc/intel/common: Add support for LPSS UART in ACPI modePatrick Rudolph
Emit ACPI code for LPSS UARTs operating in ACPI mode. In this mode the device vendor ID reads as 0xffff, the PCI devices is still operate. Add ACPI device IDs for APL, GLK, SPT, SPT_H and CNP_H. The mainboard's devicetree needs to be adapted to include the chip driver and the PCI ID when it wouldn't have been hidden. Example: chip soc/intel/common/block/uart device pci 19.2 hidden register "devid" = "PCI_DEVICE_ID_INTEL_CNP_H_UART2" end # UART #2 end Tested on Linux 5.6 with Sunrise Point ACPI ID for UART2. Tested on Windows for all other UARTs.
