mipi_csi_xx clocks are used by camera sensors. These clocks cannot be
accessed (even read) if their parent gate clock is disabled. So this
patchset also add a check to parent clocks when reading these gate
clocks which marked with the specific flag (SPRD_GATE_NON_AON).

changes from v1:
* added Rob's acked-by;

Chunyan Zhang (4):
  clk: sprd: check its parent status before reading gate clock
  dt-bindings: clk: sprd: add mipi_csi_xx clocks for SC9863A
  clk: sprd: add dt-bindings include for mipi_csi_xx clocks
  clk: sprd: add mipi_csi_xx gate clocks
