This clock controller feeds the Multimedia Display SubSystem (MDSS). It's a porting of dispcc-scuba GPL-2.0 driver from CAF msm-4.19 kernel: https://source.codeaurora.org/quic/la/kernel/msm-4.19/tree/drivers/clk/qcom/dispcc-scuba.c?h=LE.UM.4.4.1.r3 Global clock name references (parent_names) have been replaced by parent_data and parent_hws.
