Attached is a patch that you may use as a starting point to develop a
more correct patch for this device. Please bear in mind that I do _not_
expect this patch to work properly with your device, although it is
possible that it might -- it would be a big surprise. Some things to
keep in mind:
This patch uses the experimental m920x driver, currently working on the
Megasky 580... I do not know much info about this TVGo device, but I
took some guesses, and left all unknowns set up the same way as the
megasky configuration... It is highly probable that these settings will
need to be changed. For instance:
Does the TVGo device use a firmware? If so, then you must capture that
firmware and alter the configuration to make it load the correct
firmware file.
What i2c address is used by the mt2060 tuner? I guessed 0x60.
Did I configure the mt2060 config options correctly? (probably not) ...
How about the zl10353? (again, probably not)
Are the endpoints configured properly? (check in usbview)
There isn't much that I can do to help besides this... You will probably
have to change a lot around in this patch in order to make it work --
please send in revised versions of this patch if you make any progress.
The attached patch should apply cleanly against the megasky repository:
http://linuxtv.org/hg/~mkrufky/megasky
Once we have a patch that is confirmed to work properly, I can merge it
into the experimental repository... but until then, happy hacking!
Cheers,
Michael Krufky
