Enable DWAPB I2C controller support on FUJITSU-MONAKA. This will be used in the FUJITSU-MONAKA server scheduled for shipment in 2027. The DSDT information obtained when verified using an in-house simulator is presented below. Device (SMB0) { Name (_HID, "FUJI200B") // _HID: Hardware ID Name (_UID, Zero) // _UID: Unique ID ... Name (_CRS, ResourceTemplate () { Memory32Fixed (ReadWrite, 0x2A4B0000, // Address Base 0x00010000, // Address Length ) Interrupt (ResourceConsumer, Level, ActiveHigh, Exclusive, ,, ) { 0x00000159, } }) ... } The expression SMB0 is used to indicate SMBus HC#0, a string of up to four characters. Created the SMB0 object according to the following specifications: ACPI Specification 13.2. Accessing the SMBus from ASL Code https://uefi.org/htmlspecs/ACPI_Spec_6_4_html/13_ACPI_System_Mgmt_Bus_Interface_Spec/accessing-the-smbus-from-asl-code.html IPMI Specification Example 4: SSIF Interface(P574) https://www.intel.co.jp/content/www/jp/ja/products/docs/servers/ipmi/ipmi-second-gen-interface-spec-v2-rev1-1.html Signed-off-by: Yoshihiro Furudera <fj5100bi@fujitsu.com> --- Changes in v2: - Updated the commit message as per previous discussion.
