Subject: Questions on how to add support for DVB-C/T on HVR4400 and HVR5500
Date: Fri, 20 Dec 2013 06:58:41 +0100 [thread overview]
Message-ID: <52B3DC91.5070709@gentoo.org> (raw)
Hi there,
I am trying to also add support for for using SI2165 driver on HVR4400
and HVR5500 cards.
The pci subdevice id of the HVR5500 (0x0070:0xc138) is assigned to
HVR4400 in cx23885-cards.c.
Is that just because the DVB-S2 part is identical, to not add redundant
code? In this case I could just modify it to a new HVR5500 enum value.
How is a second demod wired to cx23885 in this case? Is this done via
another port, so portb for DVB-S/S2 and portc for DVB-C/T?
On HVR5500, there is a device at i2c addr 0x60, this could either be a
tuner (NXP 18271C2?) or the demod SI2165.
Or is there a need to change gpio values to get the demod out of the reset?
Does the HVR4400 contain a SI2161 demod? I cannot read the name on the
pictures, but it looks very similar the SI2165.
Regards
Matthias
