Changelog: v4: - Rebased older patch series onto latest drm-misc-next - Added patch for renaming JM functions to reflect their actual role - Fixed treatment of error code in perfcnt when enabling sample buffer AS v3: - Minor convenience fixes to patches 3 and 4 in the series - Move unmapping of maped range of BO to the function's error path in case of BO mapping failure, also for putting BO's pages - Split patch 6/8 into two: one makes sure the Job IRQ enablement mask isn't recalculated at every device reset and uses the same expression everywhere in the driver, and another one that breaks the enablement function into two stages. v2: - Removed commit that provided an explicit fence cleanup function - Added commit for removing unused Panfrost device structure member - Refactored how optional job interrupt reenabling during reset is handled - Make the way errors and successful return values are delivered from inside panfrost_mmu_as_get more according to standard. - Simplify unmapping of already mapped area when mapping the pages of a BO - Fixing management of runtime-PM reference counts when failing HW job submission.
