Add bindings, a driver supporting the PLLs and the requisite changes to the devicetrees for PolarFire SoC based boards. These clocks were already in use, but which clock specifically was chosen was decided by the synthesis tool. In our end-of-September release of our FPGA reference design, constraints will be added to force the synthesis tool to pick the "north west" CCC, making it possible to read the configuration from the CCC's registers. There are no maintainers changes in this series, but they are required due to the binding rename. I am waiting for some changes queued in the soc tree before rebasing on a later -rc before including that patch. The dts patch conflicts with some other dts patches I have submitted, so I will take the final patch myself once the rest of this is applied. Thanks, Conor. Changes since v3: - return devm_of_clk_add_hw_provider() directly in probe - add a `hw_data.num = num_clks` that got lost along the way somewhere - mark all output clocks as CLK_DIVIDER_ONE_BASED Changes since v2: - Removed the unintentionaly leftover clock-output-names - Dropped the riscv/microchip dt-binding update. I am moving it to another series so that another series for the dts, which is likely to be applied first would not depend on this series. Changes since v1: - Stopped using the dt node name to generate the clk name. Rather than use clock-output-names etc, I just opted to call each PLL after it's individual base address: cccrefclk ccc@38100000_pll0 ccc@38100000_pll0_out3 ccc@38100000_pll0_out2 ccc@38100000_pll0_out1 ccc@38100000_pll0_out0 - dt nodes are now all called "clock-controller" Conor Dooley (5): dt-bindings: clk: rename mpfs-clkcfg binding dt-bindings: clk: document PolarFire SoC fabric clocks dt-bindings: clk: add PolarFire SoC fabric clock ids clk: microchip: add PolarFire SoC fabric clock support riscv: dts: microchip: add the mpfs' fabric clock control .../bindings/clock/microchip,mpfs-ccc.yaml | 80 +++++ ...p,mpfs.yaml => microchip,mpfs-clkcfg.yaml} | 2 +- .../dts/microchip/mpfs-icicle-kit-fabric.dtsi | 27 +- .../boot/dts/microchip/mpfs-icicle-kit.dts | 4 + .../dts/microchip/mpfs-polarberry-fabric.dtsi | 5 + arch/riscv/boot/dts/microchip/mpfs.dtsi | 34 +- drivers/clk/microchip/Makefile | 1 + drivers/clk/microchip/clk-mpfs-ccc.c | 290 ++++++++++++++++++ .../dt-bindings/clock/microchip,mpfs-clock.h | 23 ++ 9 files changed, 453 insertions(+), 13 deletions(-) create mode 100644 Documentation/devicetree/bindings/clock/microchip,mpfs-ccc.yaml rename Documentation/devicetree/bindings/clock/{microchip,mpfs.yaml => microchip,mpfs-clkcfg.yaml} (96%) create mode 100644 drivers/clk/microchip/clk-mpfs-ccc.c base-commit: b90cb1053190353cc30f0fef0ef1f378ccc063c5
