Hi,
I am trying to fix the video output on the BeagleBoard xM (armv7) which is broken since a while.
I am nearly done with the config update, but I have a last problem. The TFP410 (HDMI transmitter) has a power-down GPIO handled by another chip, the TWL4030 (module also built-in). The problem is that that TWL4030 is probed _after_ the TFP410 which results in: "tfp410 encoder0: failed to parse PD gpio".
How could I probe TWL4030 _before_ the TFP410 (both modules built-in) ? In general the driver should handle the deferred probe if the dependency fails. The probe order of built-in drivers are more or less hard-coded. (If it's about modules, you can use softdep,

Indeed, deferred probe is not handled, it just fails. I will try to add it. Guillaume
In anyway, you'd better to report it to upstream to fix the issue.
