This patchset adds pinctrl driver to support pin configuration for LPASS
(Low Power Audio SubSystem) LPI (Low Power Island) pinctrl on SM8450.
This IP is an additional pin control block for Audio Pins on top the
existing SoC Top level pin-controller.
Tested this on SM8450 MTP
Thanks,
Srini
Changes since v2:
- removed unnecessary quotes in bindings
- remove lable in bindings
- fixed gpio pattern and remove an extra line

2.21.0
Add pinctrl driver to support pin configuration for LPASS
(Low Power Audio SubSystem) LPI (Low Power Island) pinctrl
on SM8450.
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.

Patch applied, the patch looks innocent and bindings are reviewed.
If Bjorn has any further remarks I can always pull it out (or you can make
patches on top).
