From 865e2eb08f51820bdefa37a80abe771b5979d440 Mon Sep 17 00:00:00 2001 From: Jakub Kicinski Date: Tue, 26 Apr 2022 10:54:36 -0700 Subject: net: hamradio: remove support for DMA SCC devices Another incarnation of Z8530, looks like? Again, no real changes in the git history, and it needs VIRT_TO_BUS. Unlikely to have users, let's spend less time refactoring dead code... Signed-off-by: Jakub Kicinski Signed-off-by: David S.

They are detected automatically. - If you have one of these cards, say Y here and read the AX25-HOWTO, - available from . - - This driver can operate multiple boards simultaneously. If you - compile it as a module (by saying M instead of Y), it will be called - dmascc. If you don't pass any parameter to the driver, all - possible I/O addresses are probed. This could irritate other devices - that are currently not in use. You may specify the list of addresses - to be probed by "dmascc.io=addr1,addr2,..."
