Yeah, that just makes it simply not program the PLL at all.
I just booted Linus's current tree on my Samsung 216BW and it works
just fine. I'll try a few other monitors I have.
If you have the time can you try these two tests?
1) In atyfb_setup_sparc(), comment out the whole block of code protected
by:
if (IS_XL(pdev->device)) {
/*
* Fix PROMs idea of MEM_CNTL settings...
*/
2) Force the:
dp = pci_device_to_OF_node(pdev);
if (dp == of_console_device) {
test to fail.
I've always been suspect of all of the special mode and MEM_CNTRL handling
we have here for Sparc. If disabling it fixes stuff, I'd happily see this
code get tossed out completely.
Thanks!
