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 v6: - add support for derated tables which are used under high temperatures - add patches to support memory-region-names property in DT - address review comments Changes in v5: - 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 Thierry Reding (6): dt-bindings: reserved-memory: Introduce memory-region-names of: reserved-memory: Support lookup of regions by name of: reserved-memory: Support multiple regions per device clk: tegra: Rename Tegra124 EMC clock source file memory: tegra: Support derated timings on Tegra210 arm64: tegra: Hook up EMC cooling device .../nvidia,tegra210-emc.yaml | 82 + .../reserved-memory/reserved-memory.txt | 2 + arch/arm64/boot/dts/nvidia/tegra210.dtsi | 37 +- drivers/clk/tegra/Makefile | 3 +- .../tegra/{clk-emc.c => clk-tegra124-emc.c} | 0 drivers/clk/tegra/clk-tegra210-emc.c | 369 +++ drivers/clk/tegra/clk-tegra210.c | 87 +- drivers/clk/tegra/clk.h | 3 + drivers/memory/tegra/Kconfig | 14 + drivers/memory/tegra/Makefile | 4 + drivers/memory/tegra/mc.h | 1 + drivers/memory/tegra/tegra210-emc-cc-r21021.c | 1744 ++++++++++++++ drivers/memory/tegra/tegra210-emc-core.c | 2099 +++++++++++++++++ drivers/memory/tegra/tegra210-emc-table.c | 94 + drivers/memory/tegra/tegra210-emc.h | 1023 ++++++++ drivers/memory/tegra/tegra210-mc.h | 49 + drivers/of/of_reserved_mem.c | 41 +- include/dt-bindings/clock/tegra210-car.h | 4 +- include/linux/clk/tegra.h | 27 + include/linux/of_reserved_mem.h | 11 + 20 files changed, 5656 insertions(+), 38 deletions(-) create mode 100644 Documentation/devicetree/bindings/memory-controllers/nvidia,tegra210-emc.yaml rename drivers/clk/tegra/{clk-emc.c => clk-tegra124-emc.c} (100%) 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-core.c create mode 100644 drivers/memory/tegra/tegra210-emc-table.c create mode 100644 drivers/memory/tegra/tegra210-emc.h create mode 100644 drivers/memory/tegra/tegra210-mc.h -- 2.24.1
