The YP-CP3's tuner is a Silicon Labs Si470x at I2C address 0x20, an Si4703 by the RDS the original firmware enables. The firmware drives it the Si470x way - writes from register 2, reads from 0x0A - starts its oscillator with TEST1 = 0x8100 and a 500 ms wait before ENABLE, and has no power or reset line for it. - config: CONFIG_TUNER SI4700 with RDS, polled (no interrupt line needed), and FM radio as an input source - si4700.c: the YP-CP3 starts the oscillator as the Sansas do - power-ypcp3.c: tuner power stubs - there is nothing to switch - the rk27xx tuner I2C glue, and "radio" in the target's configure entry - wm8751.c: audiohw_set_monitor() for a WM8750 target that plays the radio but cannot record (rk27xx has no recording yet). The tuner, on LINPUT1/RINPUT1, goes through the input PGA at +12 dB - as in the original firmware - into the output mixers, the DAC staying in the mix. The existing monitor routing lives in the recording code and switches OUT2 off, which is the YP-CP3's headphone output. Tested on a YP-CP3: stations tune and play at a sane level.
