Subject: V4L/DVB (6386): Add support for radio on CX88_BOARD_MSI_TVANYWHERE_MASTER
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=55c88610fe974c95a62e495305a7386aaac3df39;p=openwrt%2Fstaging%2Fblogic.git

V4L/DVB (6386): Add support for radio on CX88_BOARD_MSI_TVANYWHERE_MASTER

This board has some special tea5767 configuration. Basically, radio
XTAL uses a different frequency than the other supported radios. It
uses a 13 MHz XTAL.

This patch adds the proper radio gpio and tea5767 configurations for
the board.

Also, with PAL/BG, the board requires some special init for tda9887:
port1=0 port2=0 qss=1

Thanks to Serge Kolotylo and MIDImaster for their help on identifying
the proper needs for this driver.
