This IP is an additional pin control block for Audio Pins on top the existing SoC Top level pin-controller. Hardware setup looks like: TLMM GPIO[165 - 187] --> LPASS LPI GPIO [0 - 22] This pin controller has some similarities compared to Top level msm SoC Pin controller like 'each pin belongs to a single group' and so on. However this one is intended to control only audio pins in particular, which can not be configured/touched by the Top level SoC pin controller except setting them as gpios. Apart from this, slew rate is also available in this block for certain pins which are connected to SLIMbus or SoundWire Bus.
