Hi Paul! :) Im working to get Motorola EZX Phones[1] supported by mainline linux. Our audio codec is a proprietary PMIC, manufactured by TI for Motorola, named PCAP2(PTWL93017). The audio codec is connected to PXA SSP2, PXA SSP3, Baseband Processor and BCM20x5(bluetooth) in network mode. PXA is always the _slave_ of bitclock and frame, so I don't have to care about clock settings on PXA side, the codec always provides me the correct clock for the selected rate. You can find our code on git://git.openezx.org/openezx.git, ezx/current branch. (sound/soc/pxa/ezx.c and sound/soc/codecs/pcap2.c). Most of our work is based on the 2.4 kernel source releases by motorola[2], and on the atlas(MC13783) PMIC documentation[3] from Freescale (used by Motorola on newer(MAGX) phones), as we don't have documentation for PCAP2.
