The arm-smmu-qcom driver needs to hook up qcom_smmu_impl for booting up
Snapdragon platforms. Such hook-up is being done for DT boot by
matching compatibles. The series tries to handle the hook-up for ACPI
boot by looking at model identifier, which is figured out by IORT driver
using acpi_match_platform_list() helper. It helps to get Debian
installer booting with ACPI work for Qualcomm SC8180X based laptops like
Lenovo Flex 5G.
Changes for v2:
- Rather than using asl_compiler_id in IORT table, follow suggestion
from Robin Murphy to use acpi_match_platform_list() to match platform.
Shawn Guo (3):
ACPI/IORT: Consolidate use of SMMU device platdata
ACPI/IORT: Add Qualcomm Snapdragon platforms to iort_plat_info[]
