Subject: [PATCH 01/10] dt-bindings: clock: gcc-msm8917: Split to separate
 schema

From: Daniil Titov <daniilt971@...il.com>

The Qualcomm MSM8917 Global Clock controller after adding support for new
SoCs has different clock inputs, thus existing qcom,gcc-msm8909.yaml was
not describing it fully. Move the binding to it's own schema file and
document the clocks based on DTS. Add driver contributors as it's
maintainers.
