In DPG mode jpeg_v5_0_0_ring_reset() takes the DPG stop path, which only clears the JPEG_PG_MODE bit and never resets the JRBC. A hung ring is not recovered: the post-reset ring test times out and the driver falls back to a full MODE1 reset. Temporarily force the static power-gating path during the reset so the stop/start sequence power-cycles the JPEG block (JMI soft reset + power off/on), matching the jpeg_v4_0 reset which has no DPG path.
