7560d7a4f9 V4L/DVB (3317): msp3400: use v4l2_std_id and determine chip capabilities.
- Replace old norm by the v4l2_std_id values.
- Add code to correctly detect the various capabilities of the
various msp chips. It's not yet used, that's going to be the next step.

0602fbb2c8 V4L/DVB (3309): SAA7134: GPIO IRQ improvements
- Saa7134-core.c saa7134_irq(): Separate GPIO16 and GPIO18 handling. Call
IR-remote-GPIO handler only if the GPIO IRQ is "owned" by it. Added
infrastructure to branch out to a future I2C-IR IRQ handler.
saa7134-core.c saa7134_hwinit2(): Enable only the one GPIO pin and edge to
trigger an IRQ that is wired as keyup/keydown mask. IRQ will only be
generated for an actual key-down event.
saa7134-input.c flyvideo_codes[]: Replace numpad keys with normal ones. Put
meaning to mystery keys. Change some key definitions to have their functions
match their labels better. Fix typos.
saa7134-input.c flydvb_codes[]: Added new table for the larger remote that
comes with the LifeView FlyDVB series.
saa7134-input.c build_key(): In IRQ mode, signal key-down and then key-up
straight in one go.

b7f355d23c V4L/DVB (3293): Added digital support for cx88 (cx88-alsa)

- Added digital audio support for cx88-based boards that have function
  01 enabled. These boards can be identified by having PCI id 1471:8801
  or 1471:8811.

- Increased DMA buffer from 512 to 4096 seems to fix audio distortion.

- Existing audio DMA uses conflict with cx88-alsa. Should be disabled when
  cx88-alsa module is compiled.
