[PATCH v3 0/2] soc: qcom: pd-mapper: Add support for SA8775P and QCS8300

[Mohammad Rafi Shaik]

Add support for the Qualcomm SA8775P and QCS8300 SoCs to the
protection domain mapper. Add an entry to the kernel, to avoid
the need for userspace to provide this service.

changes in [v3]:
 - Added a separate protection domain from QCS8300 as suggested by Dmitry.
 - Link to V2: https://lore.kernel.org/all/20260127144315.4125110-1-mohammad.rafi.shaik@oss.qualcomm.com/

changes in [v2]:
 - Added missing GPDSP protection domain configuration as suggested by Dmitry.
 - Link to V1: https://lore.kernel.org/all/20251230102508.1491296-1-mohammad.rafi.shaik@oss.qualcomm.com/

[PATCH v3 1/2] soc: qcom: pd-mapper: Add support for SA8775P

[Mohammad Rafi Shaik]

Add support for the Qualcomm SA8775P SoC to the protection
domain mapper. SA8775P share the same protection domain
configuration as SC8280XP with an additional gpdsp domain,
except for charger_pd.

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

Is there no separate PD for CDSP1? What is the difference between CDSP
and CDSP1?

Yes, there is no dedicated PD entry for CDSP1 in the linux‑firmware,

In the device tree, there is no functional change in CDSP, only the base 
address is different.
