Merge branch 'feature/rtc_clk_impl' into 'master'
Introduce soc component, add source of rtc_clk and rtc_pm libraries This MR adds parts of the RTC library source code (initialization, clock selection functions, sleep functions). WiFi-related power management functions are kept inside the precompiled library. Most of RTC library APIs have been renamed. Default CPU frequency option in Kconfig is set to 160MHz, pending qualification of 240MHz mode at high temperatures. Register header files are moved into the new soc component, which will contain chip-specific header files and low-level non-RTOS-aware APIs (such as rtc_ APIs). Some of the files from ESP32 component were also moved: cpu_util.c, brownout.c, and the corresponding header files. Further refactoring of ESP32 component into more meaningful layers (chip-specific low level functions; chip-specific RTOS aware functions; framework-specific RTOS-related functions) will be done in future MRs. See merge request !633

* @brief Low-level RTC power, clock, and sleep functions.
|
||||
*
|
||||
* Functions in this file facilitate configuration of ESP32's RTC_CNTL peripheral.
|
||||
* RTC_CNTL peripheral handles many functions:
|
||||
* - enables/disables clocks and power to various parts of the chip; this is
|
||||
* done using direct register access (forcing power up or power down) or by
|
||||
* allowing state machines to control power and clocks automatically
|
||||
* - handles sleep and wakeup functions
|
||||
* - maintains a 48-bit counter which can be used for timekeeping
|
||||
*
|
||||
* These functions are not thread safe, and should not be viewed as high level
|
||||
* APIs. For example, while this file provides a function which can switch
|
||||
* CPU frequency, this function is on its own is not sufficient to implement
|
||||
* frequency switching in ESP-IDF context: some coordination with RTOS,
|
||||
* peripheral drivers, and WiFi/BT stacks is also required.
|
||||
*
|
||||
* These functions will normally not be used in applications directly.
|
||||
* ESP-IDF provides, or will provide, drivers and other facilities to use
|
||||
* RTC subsystem functionality.
|
||||
*
|
||||
* The functions are loosely split into the following groups:
|
||||
* - rtc_clk: clock switching, calibration
|
||||
* - rtc_time: reading RTC counter, conversion between counter values and time
|
||||
* - rtc_sleep: entry into sleep modes
|
||||
* - rtc_init: initialization
