Later it was decided to use SoC-specific compatibles instead, so "qcom,msm8916-mss-pil" is now the preferred compatible. Commit 60a05ed059a0 ("arm64: dts: qcom: msm8916: Add MSM8916-specific compatibles to SCM/MSS") updated the MSM8916 device tree to make use of the new compatible but still kept the old "qcom,q6v5-pil" as fallback. This is inconsistent with other SoCs and conflicts with the description in the binding documentation (which says that only one compatible should be present). Also, it has no functional advantage since older kernels could not handle this DT anyway (e.g. "power-domains" in the MSS node is only supported by kernels that also support "qcom,msm8916-mss-pil"). Make this consistent with other SoCs by using only the "qcom,msm8916-mss-pil" compatible.
