The cs89x0 driver is really two in one, and they are mutually exclusive: - the ISA driver was used on 486-era PCs. It likely has no remaining users, like the other ethernet drivers that got removed in linux-7.1. The DMA support in here is the last device driver use of the deprecated isa_bus_to_virt() interface, all other users are either x86 specific or or got converted to the normal dma-mapping interface. The driver was maintained by Andrew Morton at the time, based on the linux-2.2 vendor driver from Cirrus Logic. - the platform_driver instance was used on some embedded Arm boards around the same time, such as the EP7211 Development Kit. This is the same chip, but uses modern devicetree based probing and no DMA. This was added by Alexander Shiyan. Remove the ISA driver as a cleanup, including all of the outdated documentation referring to its configuration.

If you have a network (Ethernet) card belonging to this class, say Y.
