      [media] bttv: Convert to generic TEA575x interface · 1b500373
      由 Ondrej Zary 提交于 
      Remove tea575x-specific code from bttv and use the common driver instead.

Only set_frequency is implemented (signal/stereo detection or seek would
require more changes to bttv).

It works fine on Video Highway Xtreme (it actually makes the radio usable as
it currently cannot be tuned properly).

Miro/Pinnacle is untested but seems to be simple and should work.

However, I don't understand the Terratec Active Radio Upgrade code. The HW
seems to need IOR, IOW and CSEL signals that were taken from ISA bus on
older cards (IOR and IOW directly and CSEL from some address decoder) and
are emulated here using GPIOs. But the code manipulating these signals in
bttv seems to be broken - it never asserts the IOR signal. If anyone has
this HW, please test if I got that right.

      [media] [REGRESSION] bt8xx: Fix too large height in cropcap · 35ccecef
      由 Hans de Goede 提交于 
      Since commit a1fd2877:
"[media] bttv-driver: fix two warnings"
cropcap.defrect.height and cropcap.bounds.height for the PAL entry are 32
resp 30 pixels too large, if a userspace app (ie xawtv) actually tries to use
the full advertised height, the resulting image is broken in ways only a
screenshot can describe.
The cause of this is the fix for this warning:
drivers/media/pci/bt8xx/bttv-driver.c:308:3: warning: initialized field overwritten [-Woverride-init]
In this chunk of the commit:

                .name           = "NTSC",
Which replaces the overriding of cropcap.bounds.height initialization outside
of the CROPCAP macro (which also initializes it), with passing a
different sheight value to the CROPCAP macro.
There are 2 problems with this warning fix:
1) The sheight value is used twice in the CROPCAP macro, and the old code
   only changed one resulting value.
2) The old code increased the .cropcap.bounds.height value (and did not
   touch the .cropcap.defrect.height value at all) by 2, where as the fixed
   code increases it by 32, as the fixed code passes (576 + 2) + 0x20 - 2
   to the CROPCAP macro, but the + 0x20 - 2 is already done by the macro so
   now is done twice for .cropcap.bounds.height, and also is applied to
   .cropcap.defrect.height where it should not be applied at all.
This patch fixes this by adding an extraheight parameter to the CROPCAP entry
and using it for the PAL entry.
