^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 23) * As it turns out, i2c-algo-pcf is really written with i2c-elektor's
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 24) * edge-triggered ISA interrupts in mind, while the Amiga's Zorro bus has
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 25) * level-triggered interrupts. This means that once an interrupt occurs, we
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 26) * have to tell the PCF8584 to shut up immediately, or it will keep the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 27) * interrupt line busy and cause an IRQ storm.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 28)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 29) * However, because of the PCF8584's host-side protocol, there is no good
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 30) * way to just quieten it without side effects. Rather, we have to perform
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 31) * the next read/write operation straight away, which will reset the /INT
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 32) * pin. This entails re-designing the core of i2c-algo-pcf in the future.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 33) * For now, we never request an IRQ from the PCF8584, and poll it instead.
