Cover letter [PATCH V2 0/6] serial: 8250_fintek: Fix the IRQ mode and code refactoring
The following patches will fix the Fintek LPC to UARTs IRQ mode mismatch issue and code refactoring.
Some BIOS only use _OSI("Linux") to distinguish between Linux & Windows. Apply Level/Low to UART trigger mode if Windows, Edge/High otherwise. But since 2.6.23 the mainline kernel no longer returns true for _OSI("Linux"). The BIOS ASL should avoid to use _OSI() to check system type and use ACPI MADT override IRQ mode instead.
We'll try to refactoring the source code more readable with SuperIO read/write register functions.
