Driver for the PS Vita Audio CODEC chip.
The original PS Vita models and all PSTV models use a Wolfson Microelectronics WM1803 while late PS Vita Slim models (e.g. a USS-1002 unit from October 2015) use a Conexant CX20902.
The WM1803 is potentially derived from the WM8962B as the pinout and registers seem to match.
Module
This module only exists in Non-Secure world.
The module can be found in two versions at the following locations:
os0:kd/codec.skprx
/bootimage:codec.skprx
for the WM chip.bootimage:codec_cx.skprx
for the Conexant chip.
PSTV always uses the former whilst PS Vita uses the latter if SceSysStateMgr's AU_CODEC_IC_CONEXANT
check evaluates to true.
