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 .../bindings/clock/sprd,sc9863a-clk.yaml | 1 + drivers/clk/sprd/gate.c | 7 ++++ drivers/clk/sprd/gate.h | 9 ++++++ drivers/clk/sprd/sc9863a-clk.c | 32 +++++++++++++++++++ include/dt-bindings/clock/sprd,sc9863a-clk.h | 5 +++ 5 files changed, 54 insertions(+)
