Lucas Stach 02ccdbc75c drm/etnaviv: fix TS cache flushing on GPUs with BLT engine ... commit f232d9ec029ce3e2543b05213e2979e01e503408 upstream. As seen in the Vivante kernel driver, most GPUs with the BLT engine have a broken TS cache flush. The workaround is to temporarily set the BLT command to CLEAR_IMAGE, without actually executing the clear. Apparently this state change is enough to trigger the required TS cache flush. As the BLT engine is completely asychronous, we also need a few more stall states to synchronize the flush with the frontend.
