PS17, Line 263: 	  Since Lunarlake, OS pinctrl no long provides SOC GPIO pincntrl info.
              : 	  Rather, firmware is responsible for providing such info via APCI.
              : 	  Firmware can provide entire PADs or excluding those non GPP_[group]_[number]
              : 	  at the end of each community.

Subrata, Can you download Panther Lake SOC I/O BIOS Specification 830617_PTL_SOC_BIOS_Spec_Rev0p4.pdf? It has some info under 14.10 GPIO Device ACPI Requirement. Pls let me know. Thx.
