## Summary <!-- This field should contain a summary of the changes. It will be pre-filled with the commit's message and descriptions. Adjust it accordingly --> * boards/risc-v/espressif: Add DFS board support Add DFS board support for risc-v based Espressif devices * arch/risc-v/espressif: Add DFS feature Add DFS feature for riscv based Espressif devices * arch/risc-vespressif: Fix i2c slave irq callback build error Fix i2c slave irq callback build error for risc-v based Espressif devices ## Impact <!-- Please fill the following sections with YES/NO and provide a brief explanation --> Impact on user: Yes, user can use dynamic frequency scaling features to decrease power consumption <!-- Does it impact user's applications? How? --> Impact on build: No <!-- Does it impact on building NuttX? How? (please describe the required changes on the build system) --> Impact on hardware: Clock frequency can be vary instead of constant with DFS feature <!-- Does it impact a specific hardware supported by NuttX? --> Impact on documentation: No <!-- Does it impact the existing documentation? Please provide additional documentation to reflect that --> Impact on security: No <!-- Does it impact NuttX's security? --> Impact on compatibility: No <!-- Does it impact compatibility between previous and current versions? Is this a breaking change? --> ## Testing <!-- Please provide all the testing procedure. Consider that upstream reviewers should be able to reproduce the same testing performed internally --> These configs used with these variables enabled: ``` esp32c6-devkitc:pm esp32c3-devkit:pm esp32h2-devkitc:pm esp32p4-function-ev-board:pm ``` ``` CONFIG_ESPRESSIF_DFS CONFIG_ESPRESSIF_MIN_CPU_FREQ_40 ``` ### Building <!-- Provide how to build the test for each SoC being tested --> Here is the command to build: ``` make distclean && ./tools/configure.sh esp32c6-devkitc:pm && kconfig-tweak -e CONFIG_ESPRESSIF_DFS && kconfig-tweak -e CONFIG_ESPRESSIF_MIN_CPU_FREQ_40 && make olddefconfig && make -j && make download ESPTOOL_PORT=/dev/ttyUSB0 ESPTOOL_BAUD=921600 ESPTOOL_BINDIR=./ ``` ### Running <!-- Provide how to run the test for each SoC being tested --> Device connected to a USB power meter and tested ### Results <!-- Provide tests' results and runtime logs --> Here are the results - `esp32c6-devkitm`: | | picocom connected | picocom disconnected | |---------|-------------------|----------------------| | DFS on | 24 mA | 15.5 mA | | DFS off | 31.85 mA | 22.5 mA | - `esp32c3-devkit`: | | picocom connected | picocom disconnected | |---------|-------------------|----------------------| | DFS on | 20.9 mA | 12.2 mA | | DFS off | 28.5 mA | 19.9 mA | Also peripherals tested -- This is an automated message from the Apache Git Service.
