The cx23885 has a modified version of the cx25840 a/v decoder inside it.
It uses different firmware than the normal cx25840 driver already
present in Linux. As such, to support analog, I also have to push some
patches into that driver for the differing registers (and firmware).
Analog preview and analog encoder running well in lab conditions and
they are pretty stable, but I need to spend quality time cherry picking
pieces from multiple development trees to build something acceptable to
the linuxtv community.
Soon, think weeks not days.
