[media] em28xx: support for 2304:0242 PCTV QuatroStick (510e)
It is mostly copy/paste of the 520e code with setting GPIO7 removed
(no LED light).
I've worked on just released vanilla linux-3.3.0 kernel, so there may
be 1/2 lines offset to the internal working source, but most of the
code should apply cleanly.
I was able to get the DVB-C working (tuned and watched TV). Haven't
tested DVB-T (no signal atm).
Special thanks to everybody who worked on the code and to Antti
Palosaari and Devin Heitmueller who provided essential support on irc.
Hardware is based of:
Empia EM2884
Micronas DRX 3926K
NXP TDA18271HDC2
AVF4910 (not used atm)
