Subject: [PATCH v3 1/7] dt-bindings: clock: qcom: describe the GPUCC clock for SA8775P

From: Bartosz Golaszewski <bartosz.golaszewski@...aro.org>

Add the compatible for the Qualcomm Graphics Clock control module present
on sa8775p platforms. It matches the generic QCom GPUCC description. Add
device-specific DT bindings defines as well.
