From 241fc4367b3ca5d407b043599ed980304a70b91f Mon Sep 17 00:00:00 2001 From: Russell King Date: Wed, 27 Jul 2005 11:35:54 +0100 Subject: [SERIAL] Expose 8250_pci setup/removal/suspend/resume functions Re-jig the setup/removal/suspend/resume of 8250 pci ports so that they know slightly less about how they're attached to a PCI device. Expose this as the new interface for registering PCI serial ports, as well as the pciserial_board structure and associated flag definitions.

This also unuses the SPCI_* definitions in serialP.h, which can now be removed.
