It introduces the for_each_gt() macro that loops over the tiles to perform per gt actions. This patch is a combination of two patches developed originally by Abdiel, who introduced some refactoring during probe, and then Tvrtko has added the necessary tools to start using the various tiles. The second patch re-organises the sysfs interface to expose the API for each of the GTs. I decided to prioritise this patch over others to unblock Sujaritha for further development. A third series will still follow this. Thanks, Andi Patchwork: https://patchwork.freedesktop.org/series/98741/ Changelog ========= v2 -> v3 - Added Matt and Sujaritha's r-b for patch 1 and 2. - Reworded the commit of patch 2 to underline the fact that the interface is useful also when used manually. v1 -> v2 - fixed a couple of coding style issues in patch 2.
