The "Display Engine 2.0" in Allwinner newer SoCs contains a clock management unit for its subunits, like the DE CCU in A80. Add a sunxi-ng style driver for it. Signed-off-by: Icenowy Zheng <icenowy@aosc.io> --- Changes in v4: - Fixed the inconsistence between mixer_div clocks' number and real clock. Changes in v2: - Rename sunxi-de2-ccu to sun8i-de2-ccu. drivers/clk/sunxi-ng/Kconfig | 5 + drivers/clk/sunxi-ng/Makefile | 1 + drivers/clk/sunxi-ng/ccu-sun8i-de2.c | 218 ++++++++++++++++++++++++++++++++++ drivers/clk/sunxi-ng/ccu-sun8i-de2.h | 28 +++++ include/dt-bindings/clock/sun8i-de2.h | 54 +++++++++ include/dt-bindings/reset/sun8i-de2.h | 50 ++++++++ 6 files changed, 356 insertions(+) create mode 100644 drivers/clk/sunxi-ng/ccu-sun8i-de2.c create mode 100644 drivers/clk/sunxi-ng/ccu-sun8i-de2.h create mode 100644 include/dt-bindings/clock/sun8i-de2.h create mode 100644 include/dt-bindings/reset/sun8i-de2.h
