X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=09cf11806e4b4be92af76253ff9834c48b416129;p=pandora-kernel.git

viafb: split viafb_set_start_addr up

Move individual start address setting to viafb_set_primary_address and
viafb_set_secondary_address and make it more flexible to reuse it for
panning.  Using central functions makes it easier to follow HW
manipulations.

Remove crt locking as it should be only needed for timing manipulation.
Move iga_path manipulation to via_pci_probe.

Remove memset for screen cleaning as it is currently done only for the
second screen.  This is not needed for normal operation but has a little
chance of causing unwanted display artifacts.  This can be fixed later
more consistent and more efficient (using viafb_fillrect) if needed.

This is a code clenup, no notable runtime changes expected.
