Subject: [PATCH] drm/radeon: set correct number of banks for CIK chips in DCE
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

We don't have the NUM_BANKS parameter, so we have to calculate it
from the other parameters. NUM_BANKS is not constant on CIK.

This fixes 2D tiling for the display engine on CIK.
