I'm not sure if support for this tuner is not provided already by one of
the existing drivers. If not, it is ok to submit a driver for it, but you
should just call it as tda18212.
I'm c/c Antti, as he worked on some NXP drivers recently, and may be aware
if a driver already supports TDA18212.
Existing tda18212 driver I made is reverse-engineered and it is used
only for Anysee devices, which I am also responsible. That new tuner
driver is much more complete than what I have made and single driver is
naturally the correct approach.
But one thing which annoys nowadays is that endless talking of
regressions, which has led to situation it is very hard to make changes
drivers that are used for multiple devices and you don't have all those
devices to test. It is also OK to remove my old driver and use that, but
then I likely lose my possibility to make changes, as I am much
dependent on new driver maintainer. That is one existing problem which
is seen multiple times during recent years... So I am perfectly happy
with two drivers too.
I really prefer to have just one driver for each hardware component. That
makes life easier at long term. Of course, the driver needs to be properly
maintained.
I agree. Antti do you know which Anysee device you've used for reverse
engineering?
All those Anysee models are documented very well in driver file:
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/drivers/media/usb/dvb-usb-v2/anysee.c?id=refs/tags/v3.12
There seems to be 3 different Anysee models:
"anysee-E7TC(LP)" PCB: 508TC (rev0.6)
"anysee-E7T2C(LP)" PCB: 508T2C (rev0.3)
"anysee-E7PTC(LP)" PCB: 508PTC (rev0.5)
E7TC and E7PTC has TDA18212 inside tuner module DNOD44CDH086A. E7T2C has
TDA18212 inside of DNOQ44QCH106A NIM.
E7TC and E7PTC are basically same device, just different form. Other is
external USB and another internal USB. E7T2C is different device. So if
you are going to buy these, then I recommended to order E7T2C and E7TC.
regards
Antti
