NAME

6       z8530_init - Initialise a Z8530 device

SYNOPSIS

9       int z8530_init(struct z8530_dev * dev);
10

ARGUMENTS

12       dev
13           Z8530 device to initialise.

DESCRIPTION

16       Configure up a Z8530/Z85C30 or Z85230 chip. We check the device is
17       present, identify the type and then program it to hopefully keep quite
18       and behave. This matters a lot, a Z8530 in the wrong state will
19       sometimes get into stupid modes generating 10Khz interrupt streams and
20       the like.
21
22       We set the interrupt handler up to discard any events, in case we get
23       them during reset or setp.
24
25       Return 0 for success, or a negative value indicating the problem in
26       errno form.
