Manresa # Surface Pro 7+, IPU6 TGL 8086:9a19, INT33BE; 4-7 backported to a 6.19 linux-surface tree Coverage that was still missing from the other reports, all on the same machine and boot: - With the downstream unconditional 0x4800 = 0x2d write removed and only your gate in place, MIPI_CTRL00 reads 0x20 over i2c mid-stream (bit 5 only), so the result below is your code path and nothing else. - The sensor's 2x2 binned 1296x972 readout (a downstream mode, not in mainline) streams through the IPU6 hardware ISP (PSYS) at ~28.7 fps: three fresh stream starts x 60 frames, all frames unique and non-black, Bayer phase unchanged. A raw binned capture straight off the ISYS node had zero CSI-2 errors. - The CSI-2 receiver error signature at stream start/stop (the usual "Transfer FIFO overflow" / "Inter-frame packet discarded" bursts) is identical to the 0x2d build over the same five capture cycles: 15/15/20 in both. Consistent with Fil's sweep - bits 0, 2 and 3 of 0x2d were doing nothing. - Exercised on top of my ipu-bridge rebind series, with the "clock-noncontinuous" property name routed through ipu_property_names as suggested in my reply to 7/7: PCI remove -> module unload -> rescan -> reload re-enumerates all three sensors without -EEXIST and captures afterwards. The IR (OV7251) and rear (OV8865) cameras are unaffected before and after. Backport notes, in case they help anyone else on 6.19: 2/7 and the table hunks of 7/7 need hand placement (no OVTI5675/HIMX1092 entries there), and 5/7 changes the ipu_bridge_init()/ipu_bridge_parse_ssdb() CRCs, so intel-ipu6 has to be rebuilt alongside ipu-bridge under MODVERSIONS; isys and psys only import ipu_bridge_instantiate_vcm and are fine.
