The commit defines a new common CPU symbol `CPU_COMMON_ESP32X` in Kconfig that is used by all `CPU_FAM_ESP32x` symbols which selects features, modules and packages that are common for all ESP32x SoC variants. This avoids the selection of features, modules and packages again and again for each ESP32x SoC variant.

CPU clock frequency used (default 80 MHz).
|
|
Please note that peripherals such as I2C or SPI might not work at
|
|
the specified clock frequency if the selected CPU clock frequency
|
|
is too low. These peripherals are clocked by the APB clock, which
|
|
has a clock rate of 80 MHz for CPU clock frequencies greater than
|
|
or equal to 80 MHz, but is equal to the CPU clock frequency for
|
|
CPU clock frequencies less than 80 MHz. Thus, for SPI, the APB
|
|
clock rate must be at least five times the SPI clock rate. For the
|
|
I2C hardware implementation, the APB clock rate must be at least
|
|
3 MHZ to use I2C in fast mode with a I2C clock rate of 400 kHz.
|
|
For the I2C software implementation, the maximum I2C clock rate
|
|
is 1/130 times the CPU clock rate.
