powerpc: backport AST graphic driver updates for OpenPower
Dear Maintainers,
When Using the newest Jessie kernel in TYAN TN71-BP012 server, we
found that the AST graphic driver can't work properly(no output from
vga).
There are bug reports already in Ubuntu:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1420627
and they provide patches here: we have test these patches, it can work.
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1420627/+attachment/4318303/+files/ast-backports.tar.gz
But the Ubuntu Kernel Team only backport these patches in 3.19.y,
not in 3.16.y, so should Debian Jessie do these?
regards,
Eric
