[PATCH v2] soc: qcom: pd-mapper: Add support for SA8775P and QCS8300
Posted by Mohammad Rafi Shaik 1 week, 4 days ago 
Add support for the Qualcomm SA8775P and QCS8300 SoCs to the
protection domain mapper. SA8775P and QCS8300 share the same
protection domain configuration as SM8550 with an additional
gpdsp domain, except for charger_pd and mpss_pd.

Add an entry to the kernel, to avoid the need for userspace to
provide this service.

I don't see sensors PD in linux-firmware.

THis is definitely not correct, QCS8300 and SA8755P have different sets
of protection domains.

ACK,

Sorry for the incorrect mapping,

will make sure never happen again, will cross check with linux-firmware 
and update the change

Thank you for highlighting this.
