From 99e09eac25f752b25f65392da7bd747b77040fea Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Thu, 27 Mar 2008 23:18:30 -0300 Subject: V4L/DVB (7448): Add support for Kworld ATSC 120 This board has a s5h1409 demod, plus a xc30x8 tuner (probably, xc3018). This patch adds proper support for radio, video, s-video, composite and ATSC. However, support for radio and video depends on having s5h1409 i2c gate open, otherwise, xc30x8 chip won't be visible. For a better support, some rework is needed on cx88 driver, to allow adding xc30x8 to i2c bus without sending i2c 0 byte reading to 0xc2 address. Thanks to Vanessa Ezekowitz for helping to figure out the proper parameters for s5h1409 and the GPIO pins used by each configuration.
