[PATCH v3 1/3] [media] si2157: Add support for Si2141-A10

[PATCH v3 1/3] [media] si2157: Add support for Si2141-A10

[Stefan Brüns]

The Si2141 needs two distinct commands for powerup/reset, otherwise it
will not respond to chip revision requests. It also needs a firmware
to run properly.

[PATCH v3 3/3] [media] dvbsky: MyGica T230C support

[Stefan Brüns]

Mygica T230 DVB-T/T2/C USB stick support. It uses the same FX2/Si2168
bridge/demodulator combo as the other devices supported by the driver,
but uses the Si2141 tuner.
Several DVB-T (MPEG2) and DVB-T2 (H.265) channels were tested, as well as
the included remote control.

Instead of this series, a different patchset was accepted, although
Antti raised concerns about at least 2 of the 3 patches accpeted, more
specifically the si2157 patch contains some bogus initialization code,
and the T230C support were better added to the dvbsky driver instead of
 cxusb.

Kind regards,

Patch set looks good. I ordered that device and it arrived yesterday. I 
will handle that during 2 weeks - it is now skiing holiday and I am at 
France alps whole next week. So just wait :)

Sorry, I likely missed those comments when reviewed the patch series.

As the applied series won't cause regressions, as all init code seem
specific to the new tuner, I won't be reverting the patchsets, but
wait for Antti to be able to do a deeper look on it.

Please submit a patch removing the bogus init code, for Antti's
review.

IMHO, the better here would be to merge both drivers into one, as they
seem to be doing very similar stuff. So, I can't find a good reason
why we should keep both drivers upstream. As dvbsky uses dvb-usb-v2,
the best would be to move the board-specific code from cxusb into
the dvbsky driver, and drop the cxusb driver.

Feel free to submit such patch too.

"Merging" the drivers comes down to reverting the patch to cxusb, and instead 
applying Patch 3 from my series. I won't port support for any other stick, as 
I lack the hardware for testing.

@Annti - hope you enjoyed skiing, did you have time for looking into the

[PATCH v3 0/3] Add support for MyGica T230C DVB-T2 stick

[Stefan Brüns]

The required command sequence for the new tuner (Si2141) was traced from the
current Windows driver and verified with a small python script/libusb.
The changes to the Si2168 and dvbsky driver are mostly additions of the
required IDs and some glue code.
