i2c: amd-asf: Clear remote IRR bit to get successive interrupt

Browse source

To ensure successive interrupts upon packet reception, it is necessary to
clear the remote IRR bit by writing the interrupt number to the EOI
register. The base address for this operation is provided by the BIOS and
retrieved by the driver by traversing the ASF object's namespace.
