[PATCH 0/2] saa7115: add detection code for gm7113c

[Mauro Carvalho Chehab]

Hi Jen,

Ezequiel pinged me today on IRC warning me that, at least on his
stk1160 device with gm1113c, the analog demod, labeled as GM1113C 1145,
returns 0x10 on all reads (e. g. version 0).

So, I decided to write a patch with the ideas I exposed on my last
emails, plus a code that would allow saa7115 to work with both
auto-detection and manual binding.

I didn't add there the part of your code with the gm7113c specifics,
as I prefer if you can rebase your patch on the top of those two,
of course assuming that they'll work.

Patches weren't test yet.

Jen/Ezequiel,

Could you please test them?

[PATCH 1/2] saa7115: move the autodetection code out of the probe function

[Mauro Carvalho Chehab]

As we're now seeing other variants from chinese clones, like
gm1113c, we'll need to add more bits at the detection code.

So, move it into a separate function.

Tiny nitpick: weird indentation and inconsistent

[PATCH 2/2] saa7115: add detection code for gm7113c

[Mauro Carvalho Chehab]

Adds a code that (auto)detects gm7113c clones. The auto-detection
here is not perfect, as, on contrary to what it would be expected
by looking into its datasheets some devices would return, instead:

	saa7115 0-0025: chip 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 @ 0x4a is unknown

(found on a device labeled as GM7113C 1145 by Ezequiel Garcia)

Is this weird comment indentation correct?

Hi Mauro,

Thanks for the patch!

I've done some quick testing on stk1160+saa7113 and also stk1160+gm7113c,
everything looks OK (except from the minor misname comment, see the patch 2/2).

Let me do some more testing just to be sure.

@Jon: Do you mind sending the standard fix for gm7113c? We need those
to make stk1160+gm7113c work. I'll put my Tested-by so we can merge it!

FWIW, some user reported he didn't need those quirks to capture a PAL (?)
source. But in my experience, I *do* need them, otherwise I get a noisy
PAL-Nc output and no video capture at all on NTSC/PAL-M.

Thanks a lot for the good work!

Thanks for testing and for the comments.

Just respin a v2 fixing the pointed minor pitnicks.

Ok. I don't intend to merge it without Jon's patches.
