You should base your work off the master branch. The tda18271 driver in that tree should work well enough for you. I don't know anything about the IF within the saa7136 -- I would guess it is something like a tda8290 or tda8295, which may need some work for analog support. For digital tv, you can attach the tda18271 the same way as is done in cx23885-dvb for the hvr1800, with alt_tuner=1.
You'll have some work to do to get the saa7136 analog video decoder working as well... I've heard it may be compatible with the saa7134 code, but that driver currently expects to be used as a PCI bridge.
Given the CY7C68013A, you probably don't want to touch any of the dib0700 code, although we still don't know what digital demod / channel decoder is used in your device. Are there any other chips inside?
