The following patches will fix the Fintek LPC to UARTs IRQ mode mismatch
issue, code refactoring and this series patches should follow by patch
rename IRQ_MODE macro on
'commit 87a713c8ffca ("8250/fintek: rename IRQ_MODE macro")'.
with tty-linus branch.
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.
Ricardo Ribalda Delgado suggest fixing a potential NULL pointer
dereference with applied patch
fix the mismatched IRQ mode on
'commit 4da22f1418cb ("serial: 8250_fintek: fix the mismatched IRQ mode")'.
had been implemented with 8250_fintek: Set IRQ Mode when port probed.
