This series adds CRG driver for Hi3798MV100 SoC.
v2: move bindings to a separate patch
v3: fix bindings commit message, reorganize patches
v4: add ethernet and gpu clocks
v5: add complex clock
David Yang (5):
clk: hisilicon: Rename Hi3798CV200 to Hi3798
clk: hisilicon: Extract common functions
clk: hisilicon: Add complex clock for Hi3798
dt-bindings: clock: Add Hi3798MV100 CRG
clk: hisilicon: Add CRG driver for Hi3798MV100 SoC
