Hi, The cx22702 demod has an i2c gate which is opened and closed on demand to allow traffic to pass through to the pll. By default it's open. With the Nova-T-PCI this is fine, because all access to the PLL naturally happens via the demod driver. The cx22702 driver is the obvious place to unlock and lock the gate... it's a function of the part. However, the breaks the upcoming HVR1100 driver (and will also break the next two drivers to come after the HVR1100). The HVR1100 driver is a Hybrid Analog (V4L) and DVB-T animal. The same PLL is used in both cases. Analog works normally on a clean boot, but as soon a DVB is used, the gate is locked and subsequent V4L analog I2C activity fails with -REMOTEIO errors. As you'd expect, DVB continue to work happily. For the time being I've removed the gate locking mechanism from the cx22702 driver. However, other than removing the gate/lock permanently, or manually via a parameter, does anyone have any suggestions? Anyone know how the other demods do this? (Or if they have this feature?) Steve
