Z8530_WRITE_PORT(9) Internal Functions Z8530_WRITE_PORT(9) NAME z8530_write_port - Architecture specific interface function SYNOPSIS void z8530_write_port(unsigned long p, u8 d); ARGUMENTS p port to write d value to write DESCRIPTION Write a value to a port with delays if need be. Note that the caller must hold locks to avoid read/writes from other contexts violating the 5uS rule In the longer term this should become an architecture specific section so that this can become a generic driver interface for all platforms. For now we only handle PC I/O ports with or without the dread 5uS sanity delay. AUTHOR Alan Cox <alan@lxorguk.ukuu.org.uk> Author. COPYRIGHT Kernel Hackers Manual 3.8.
