From: Thierry Reding <treding@xxxxxxxxxx> This series introduces the EMC clock scaling support for Tegra210. The EMC table of supported frequencies is passed to the kernel via a device tree reserved memory region. Joseph posted the v4 of this series[0] about a year ago. I've dusted it off a bit and tried to address all of the comments that Dmitry had made in response to v4. Changes in v4: - major rework to split this into a clk driver and an EMC driver - refactored some code to remove duplication and improve readability - removed some unused code and variables Thierry [0]: https://lore.kernel.org/linux-arm-kernel/20190529082139.5581-1-josephl@xxxxxxxxxx/ Joseph Lo (8): clk: tegra: Add PLLP_UD and PLLMB_UD for Tegra210 clk: tegra: Export functions for EMC clock scaling clk: tegra: Implement Tegra210 EMC clock dt-bindings: memory: tegra: Add external memory controller binding for Tegra210 memory: tegra: Add EMC scaling support code for Tegra210 memory: tegra: Add EMC scaling sequence code for Tegra210 arm64: tegra: Add external memory controller node for Tegra210 clk: tegra: Remove the old emc_mux clock for Tegra210 .../nvidia,tegra210-emc.yaml | 83 + arch/arm64/boot/dts/nvidia/tegra210.dtsi | 11 + drivers/clk/tegra/Makefile | 1 + drivers/clk/tegra/clk-tegra210-emc.c | 352 ++++ drivers/clk/tegra/clk-tegra210.c | 83 +- drivers/clk/tegra/clk.h | 3 + drivers/memory/tegra/Kconfig | 10 + drivers/memory/tegra/Makefile | 1 + drivers/memory/tegra/tegra210-emc-cc-r21021.c | 1782 ++++++++++++++++ drivers/memory/tegra/tegra210-emc.c | 1800 +++++++++++++++++ drivers/memory/tegra/tegra210-emc.h | 1065 ++++++++++ include/dt-bindings/clock/tegra210-car.h | 4 +- include/linux/clk/tegra.h | 26 + 13 files changed, 5202 insertions(+), 19 deletions(-) create mode 100644 Documentation/devicetree/bindings/memory-controllers/nvidia,tegra210-emc.yaml create mode 100644 drivers/clk/tegra/clk-tegra210-emc.c create mode 100644 drivers/memory/tegra/tegra210-emc-cc-r21021.c create mode 100644 drivers/memory/tegra/tegra210-emc.c create mode 100644 drivers/memory/tegra/tegra210-emc.h -- 2.24.1
