Subject: [PATCH v2 0/3] arm-smmu-qcom: Create qcom_smmu_impl for ACPI boot
Date: Fri,  2 Apr 2021 11:55:59 +0800	[thread overview]
Message-ID: <20210402035602.9484-1-shawn.guo@linaro.org> (raw)

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.
