[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) Signed-off-by: Ivan Kalvachev <ikalvachev@gmail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
