Z8530_INIT(9)                       Public Functions Provided                       Z8530_INIT(9)



NAME
       z8530_init - Initialise a Z8530 device

SYNOPSIS
       int z8530_init(struct z8530_dev * dev);

ARGUMENTS
       dev
           Z8530 device to initialise.

DESCRIPTION
       Configure up a Z8530/Z85C30 or Z85230 chip. We check the device is present, identify the
       type and then program it to hopefully keep quite and behave. This matters a lot, a Z8530
       in the wrong state will sometimes get into stupid modes generating 10Khz interrupt streams
       and the like.

       We set the interrupt handler up to discard any events, in case we get them during reset or
       setp.

       Return 0 for success, or a negative value indicating the problem in errno form.
