Hauppauge device HVR1955 and HVR1975 are old Cypress based
devices. When originally produced the demods were lacking
upstream drivers and the tuner was unsupported. Well fast
forward to now and the only thing missing is the identification
of si2177 tuner in the si2157 driver, as well as extension
of the pvrusb2 driver to accomodate i2c client devices
and multiple frontends. This series addresses what is necessary.

QAM/ATSC are fully tested and work, the DVB tuning
*should* work, but is completely untested. Both demod
drivers are compatible with multiple frontend usage due
to previous patches I've submitted, so things should
work in pvrusb2 as well.

Composite video input is tested. Unable to test s-video,
but it should work. Radio is fully untested. Analog TV is
a work in progress, coming soon.

HVR-1955:
- LGDT3306a ATSC/QAM demod
- si2177 tuner
- cx25840 decoder for analog tv/composite/s-video/audio

HVR-1975 dual-frontend:
- LGDT3306a ATSC/QAM demod
- si2168 DVB-C/T/T2 demod
- si2177 tuner
- cx25840 decoder for analog tv/composite/s-video/audio

Works in ATSC and QAM as is, DVB is completely untested.

Firmware required.

All changes are equivalent and backwards compatible.
All current devices have been changed to use fe[0]
Cleanup has been added to dvb init to support cleanup after failure.

Hauppauge device HVR1955 and HVR1975 are old Cypress based
devices. When originally produced the demods were lacking
upstream drivers and the tuner was unsupported. Well fast
forward to now and the only thing missing is the identification
of si2177 tuner in the si2157 driver, as well as extension
of the pvrusb2 driver to accomodate i2c client devices
and multiple frontends. This series addresses what is necessary.

QAM/ATSC are fully tested and work, the DVB tuning
*should* work, but is completely untested. Both demod
drivers are compatible with multiple frontend usage due
to previous patches I've submitted, so things should
work in pvrusb2 as well.

Composite video input is tested. Unable to test s-video,
but it should work. Radio is fully untested. Analog TV is
a work in progress, coming soon.

HVR-1955:
- LGDT3306a ATSC/QAM demod
- si2177 tuner
- cx25840 decoder for analog tv/composite/s-video/audio

HVR-1975 dual-frontend:
- LGDT3306a ATSC/QAM demod
- si2168 DVB-C/T/T2 demod
- si2177 tuner
- cx25840 decoder for analog tv/composite/s-video/audio

Changes since v1:
- Patch 4/4 build fixes and reorganization

Works in ATSC and QAM as is, DVB is completely untested.

Firmware required.

  To: linux-media, mchehab; +Cc: Brad Love

Hauppauge device HVR1955 and HVR1975 are old Cypress based
devices. When originally produced the demods were lacking
upstream drivers and the tuner was unsupported. Well fast
forward to now and the only thing missing is the identification
of si2177 tuner in the si2157 driver, as well as extension
of the pvrusb2 driver to accomodate i2c client devices
and multiple frontends. This series addresses what is necessary.

QAM/ATSC are fully tested and work, the DVB tuning
*should* work, but is completely untested. Both demod
drivers are compatible with multiple frontend usage due
to previous patches I've submitted, so things should
work in pvrusb2 as well.

Composite video input is tested. Unable to test s-video,
but it should work. Radio is fully untested. Analog TV is
a work in progress, coming soon.

HVR-1955:
- LGDT3306a ATSC/QAM demod
- si2177 tuner
- cx25840 decoder for analog tv/composite/s-video/audio

HVR-1975 dual-frontend:
- LGDT3306a ATSC/QAM demod
- si2168 DVB-C/T/T2 demod
- si2177 tuner
- cx25840 decoder for analog tv/composite/s-video/audio

Since v2:
- Patch 4/4 build fix
Changes since v1:
- Patch 4/4 build fixes and reorganization


Brad Love (4):
  si2157: add detection of si2177 tuner
  pvrusb2: Add multiple dvb frontend support
  pvrusb2: Add i2c client demod/tuner support
  pvrusb2: Add Hauppauge HVR1955/1975 devices

All changes are equivalent and backwards compatible.
All current devices have been changed to use fe[0]
Cleanup has been added to dvb init to support cleanup after failure.

Why you added 05 to that file name? I added that spare number for cases 
you have to replace firmware to another for some reason thus by default 
case it should be 01.

Barring any explanation of the naming convention, I made it look similar
to the previous two, while reflecting the firmware version. This is
firmware 3.0.5. I have no problem "starting from 1", but reflecting the
firmware version seemed like the sane idea. I'll resubmit if desired.

Brad

Hi Antti,

Whatever firmware name convention policy you decide works for me, but
it would be really cool if you could send a patch ading a comment just
before the firmware naming macros documenting it, as it would avoid 
further discussions and patch resubmissions ;-)

Thanks,

Hauppauge device HVR1955 and HVR1975 are old Cypress based
devices. When originally produced the demods were lacking
upstream drivers and the tuner was unsupported. Well fast
forward to now and the only thing missing is the identification
of si2177 tuner in the si2157 driver, as well as extension
of the pvrusb2 driver to accomodate i2c client devices
and multiple frontends. This series addresses what is necessary.

QAM/ATSC are fully tested and work, the DVB tuning
*should* work, but is completely untested. Both demod
drivers are compatible with multiple frontend usage due
to previous patches I've submitted, so things should
work in pvrusb2 as well.

Composite video input is tested. Unable to test s-video,
but it should work. Radio is fully untested. Analog TV is
a work in progress, coming soon.

HVR-1955:
- LGDT3306a ATSC/QAM demod
- si2177 tuner
- cx25840 decoder for analog tv/composite/s-video/audio

HVR-1975 dual-frontend:
- LGDT3306a ATSC/QAM demod
- si2168 DVB-C/T/T2 demod
- si2177 tuner
- cx25840 decoder for analog tv/composite/s-video/audio

Since v3:
- Fix firmware name to be consistent
Since v2:
- Patch 4/4 build fix
Changes since v1:
- Patch 4/4 build fixes and reorganization

Works in ATSC and QAM as is, DVB is completely untested.

Firmware required.

All changes are equivalent and backwards compatible.
All current devices have been changed to use fe[0]
Cleanup has been added to dvb init to support cleanup after failure.

Includes support to identify and use two Hauppauge device.
HVR-1955:
- LGDT3306a ATSC/QAM demod
- si2177 tuner
- cx25840 decoder for analog tv/composite/s-video/audio

HVR-1975 dual-frontend:
- LGDT3306a ATSC/QAM demod
- si2168 DVB-C/T/T2 demod
- si2177 tuner
- cx25840 decoder for analog tv/composite/s-video/audio

Since v2:
- Fix build with VIDEO_PVRUSB2_DVB enabled
Changes since v1:
- Fix build with VIDEO_PVRUSB2_DVB disabled
- Insert 160xxx code lower, so 75xxx profile is not split
- Reorganize 160xxx board profile
- Share config where possible

Just very minor note. Here you are adding suppport for 2 frontends, but
you're not explaining why. I would add something like "This is to add support
for Hauppauge HVR1955/1975 devices which will be done in a later commit",
to the commit message. Alternatively you could merge the two commits.

These need le16_to_cpu() else it will not work on big-endian machines.

usleep_range() is preferred (for delays <= 10), I think. Maybe 10ms is too
long anyway and msleep(1) is enough.

Sorry that was wrong. usleep_range() is preferred 1ms - 20ms, see:

Hi Shawn,

Thanks for reviewing things. Please explain what your rationale is for
arbitrarily reducing the delay to 1ms? I'm a Hauppauge engineer, this is
a Hauppauge device, I'm going off Hauppauge documentation and reference
code...and it says 10ms. I'll change to the proper sleep function,
apologies for missing this instance, but the delay will stay at 10ms as
that is what my documentation says.

Regards,

Brad

Hi Sean,

I'll add a note to the commit message. Combining the commits seems
bizarre and contrary to "one issue in a commit."

I had not seen a device before that needed reset to be asserted for so long.
Clearly I was completely wrong there.

All I was trying to point out that either the msleep() should be reduced
if possible else usleep_range() should be used. I probably could have
expressed that more clearly.

Hi Shawn,

Just found time to get back to this. I fixed all the checkpatch strict
warnings, no problem. Then I noticed a few comments of yours that I
somehow missed first time around. I've replied inline to those.

I did not originate the board profile part. I do see the similar
notation used throughout this particular driver, but I cannot state the
rational in setting it like that. In v5 I have this just set these
properties to 1.

Are you sure about this? This isn't doing byte order comparison, this is
a simple number equivalence. The compiler should be taking the two byte
hex values, and inserting them into memory however the architecture
dictates, correct? All constant values are interpreted by the compiler
as little endian, but they're stored based on endianess.

Same comment here. The rest of your concerns have been handled.

I'm pushing up a v5 of this series now, without the le16_to_cpu bit
done, until that detail is reviewed again.

Cheers,

Brad

Hi Sean,

Discussed this with Mauro on irc. I went ahead and made the le16_to_cpu
fixes and set up v6. The series should be good to go now.

Cheers,

Brad

Yes. Values don't have endianness, only memory loads/stores. So the
constant doesn't have endianness but the fields idProduct and idVendor do.
Those fields are __le16. 

__le16 is a typedef to __u16. The compiler won't do endian conversion
for you. The __le16 typedef is just there for static analysis.

If you run sparse you should see an warning (make C=1).
