Hi George,
A data point from the Intel model, which has the same sensor: revision
0x1111, firmware patch 2.11, and 0x0329 reads 0x01 after power-on there
too. My vd55g0 driver writes ISL_ENABLE = 0 once per power-on, in
software standby right after boot, together with the clock and output
settings, and with LINE_LENGTH 1200 the sensor then streams Y8 and Y10 in
every mode. So here, writing 0 there does not stop the output by
itself. vd55g1 writes it at every stream start instead, which may be the
difference.
Thank you for offering to test my driver on the Snapdragon model. I will
Cc you when it is posted.
Sergey
