This series adds support for the MPLL block that is present in MStar/SigmaStar ARMv7 SoCs. This block is intended to be set and forgotten about before Linux is running so all it actually does it read the registers and calculate what the output frequencies should be. We only care about this block because there are upstream dividers, gates, muxes etc that need something between the input crystal and themselves to calculate their own rates. I think this needs to be applied after the GPIO series[0] that is currently inflight. 0 - https://lore.kernel.org/linux-gpio/20201109121731.1537580-1-daniel@xxxxxxxx/ Daniel Palmer (6): dt-bindings: clk: mstar msc313 mpll binding header dt-bindings: clk: mstar msc313 mpll binding description clk: mstar: MStar/SigmaStar MPLL driver ARM: mstar: Select MSTAR_MSC313_MPLL ARM: mstar: Add the external clocks to the base dsti ARM: mstar: Add mpll to base dtsi .../bindings/clock/mstar,msc313-mpll.yaml | 58 ++++++ MAINTAINERS | 3 + arch/arm/boot/dts/mstar-v7.dtsi | 27 +++ arch/arm/mach-mstar/Kconfig | 1 + drivers/clk/Kconfig | 1 + drivers/clk/Makefile | 1 + drivers/clk/mstar/Kconfig | 5 + drivers/clk/mstar/Makefile | 6 + drivers/clk/mstar/clk-msc313-mpll.c | 177 ++++++++++++++++++ include/dt-bindings/clock/mstar-msc313-mpll.h | 19 ++ 10 files changed, 298 insertions(+) create mode 100644 Documentation/devicetree/bindings/clock/mstar,msc313-mpll.yaml create mode 100644 drivers/clk/mstar/Kconfig create mode 100644 drivers/clk/mstar/Makefile create mode 100644 drivers/clk/mstar/clk-msc313-mpll.c create mode 100644 include/dt-bindings/clock/mstar-msc313-mpll.h -- 2.29.2
