From 82b7d0cf8c426b98ac8a737531f053585f7d4a58 Mon Sep 17 00:00:00 2001 From: Cliff Huang Date: Mon, 11 Apr 2022 18:49:57 -0700 Subject: mb/intel/adlrvp: Add 5G WWAN ACPI support for ADL-P RVP Add FM350GL 5G WWAN support using drivers/wwan/fm and additional PM features from RTD3. PCIe root port: 6 (1 based) clock source & request: 5 (0 based) GPIOs: WWAN_PERST_N: GPPC_C5 WWAN_RST_N: GPPC_F14 WWAN_FCP_OFF_N: GPPC_F15 WWAN_WAKE_N: GPPC_D18 WWAN_PWREN: GPPC_F21 WWAN_DISABLE_N: GPPC_D15 CLKREQ5_WWAN_N: GPPC_H23 TEST=Check SSDT table to see if the PXSX device and PowerResource RTD3 are generated under the root port.
