refactor(clk): split clock HAL into separate component Closes IDF-14108 See merge request espressif/esp-idf!44768
esp_hal_i2c
⚠️ This HAL component is still under heavy development at the moment, so we don't guarantee the stability and backward-compatibility among versions.
The esp_hal_i2c component provides a Hardware Abstraction Layer of I2C for all targets supported by ESP-IDF.
In a broad sense, the HAL layer consists of two sub-layers: HAL (upper) and Low-Level(bottom). The HAL layer defines the steps and data that is required to operate a peripheral (e.g. initialization, start and stop). The low-level is a translation layer above the register files under the soc component, it only covers general conceptions to register configurations.
The functions in this file mainly provide hardware abstraction for IDF peripheral drivers. For advanced developers, the HAL layer functions can also be directly used to assist in implementing their own drivers. However, it needs to be mentioned again that the interfaces here do not guarantee stability.
