acpi: drop serial/parallel enable bits from dsdt
The _STA methods for COM+LPT used to reference them, but that isn't the case any more. piix4 DSDT changes: Scope (_SB.PCI0) { Device (ISA) { Name (_ADR, 0x00010000) // _ADR: Address OperationRegion (P40C, PCI_Config, 0x60, 0x04) - Field (^PX13.P13C, AnyAcc, NoLock, Preserve) - { - Offset (0x5F), - , 7, - LPEN, 1, - Offset (0x67), - , 3, - CAEN, 1, - , 3, - CBEN, 1 - } } } ich9 DSDT changes: Scope (_SB.PCI0) { Device (ISA) { Name (_ADR, 0x001F0000) // _ADR: Address OperationRegion (PIRQ, PCI_Config, 0x60, 0x0C) OperationRegion (LPCD, PCI_Config, 0x80, 0x02) Field (LPCD, AnyAcc, NoLock, Preserve) { COMA, 3, , 1, COMB, 3, Offset (0x01), LPTD, 2 } - - OperationRegion (LPCE, PCI_Config, 0x82, 0x02) - Field (LPCE, AnyAcc, NoLock, Preserve) - { - CAEN, 1, - CBEN, 1, - LPEN, 1 - } } } Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Reviewed-by: Igor Mammedov <imammedo@redhat.com> Message-Id: <20200619091905.21676-10-kraxel@redhat.com> Reviewed-by: Michael S.
