Subject: [PATCH v2 00/11]  Add c8sectpfe LinuxDVB demux driver

Hi Maruro and linux-media folks,

This patchset adds support for a LinuxDVB demux driver for the
ST STB stih407 family SoC's. Mauro - it is what I spoke to you about
when we met at ELC-E in Dusseldorf last year.

One big advantage of having a upstream demux driver for ST
SoC's is that it will be easier to maintain support for the ST demodulators
and tuners which are already upstream (and also add support for newer demods
such as the stv6120 and stv910). As this driver allows ST NIM reference boards
(which typically have a tuner/demod combination on)
to be used easily with a upstream kernel on ST STB reference designs.

Up until now it is not easy to test stv0367, stv6110 stv90x.c demod and tuner
drivers which are supported upstream with ST STB reference hardware,
and as such makes helping support these devices difficult.

It also furthers the aim of having a completely open source A/V pipeline for STi
chipsets. A upstream DRM driver is already merged for STi SoC's. ALSA SoC is
current under review, and when this driver is accepted we would have a totaly
open source frontend support (tuner->demod->demux) :-)

This initial patchset adds support for the following demux HW called c8sectpfe: -
* Input Block HW
* HW PID filtering
* memdma engine (moves TS from input block sram to RAM)

The driver creates one Linux DVB adapter, and each tsin channel which is
described in DT has a set of LDVB device nodes.

Currently the driver supports 7 tsin channels. This driver has been tested with
the stih407-b2120 board and stih410-b2120 reference design boards, and currently
we support the following DVB fronend cards:
 - STMicroelectronics DVB-T B2100A (STV0367 + TDA18212)
 - STMicroelectronics DVB-S/S2 STV0903 + STV6110 + LNBP24 board

This patchset also includes some small changes to stv0367.c to get
the upstream driver working correctly with the ST NIM reference board. Also Joe
Perches dvb-pll patch is included with this series.

regards,

Peter.
