Subject: [PATCH 0/4] add mipi_csi_xx gate clocks for SC9863A
From: Chunyan Zhang <chunyan.zhang@...soc.com>
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).
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
