ESP32 in revision0 and revision1 uses touchpad to provide
current to oscillate xtal 32k. But revision2 and revision3
do not need to do that.
Note: touchpad can not work and toupad/ULP wakeup sources
are not available when toupad provides current to xtal 32k
ESP32 lets the user choose from using Vref, Lookup Table, and Two-Point Calibration. In ESP32S2 only two-point calibration is supported. This commit support these changes in idf.

This commit adds TWAI driver support for the
ESP32-S2. The following features were added:
- Expanded BRP support
- Expanded CLKOUT Divider Support
- Updated example READMEs
Bugfix(I2S): Fix i2s_comm_format_t configuration parameter does not match the TRM bug
Closes IDFGH-3040, IDFGH-2913, IDFGH-578, IDFGH-2408, and IDFGH-3117

* Replaced crypotoauthlib with esp-cryptoauthlib
* Added menuconfig option for esp-tls about using HSM
* Added error codes for HSM in esp-tls,
* Added support to select different type of ATECC608A chips
* Added README, updated docs
* tcp_transport: Added option to enable secure_element for ssl
Closes https://github.com/espressif/esp-idf/issues/4432
* Add options to mbedtls for hardware acceleration
* Disable mbedtls EC curves if hardware acceleration is selected
since the hardware will have to define the curves supported
* Add a hardware ecdsa example
The SPI bus lock on SPI1 introduces two side effects:
1. The device lock for the main flash requires the
`CONFIG_FREERTOS_SUPPORT_STATIC_ALLOCATION` to be selected, however this
option is disabled by default in earlier IDF versions. Some developers
may find their project cannot be built by their old sdkconfig files.
2. Usually we don't need the lock on the SPI1 bus, due to it's
restrictions. However the overhead still exists in this case, the IRAM
cost for static version of semaphore functions, and the time cost when
getting and releasing the lock.
This commit:
1. Add a CONFIG_SPI_FLASH_BYPASS_MAIN_LOCK option, which will forbid the
space cost, as well as the initialization of the main bus lock.
2. When the option is not selected, the bus lock is used, the
`CONFIG_FREERTOS_SUPPORT_STATIC_ALLOCATION` will be selected explicitly.
3. Revert default value of `CONFIG_FREERTOS_SUPPORT_STATIC_ALLOCATION`
to `n`.

* fix dac dma mode issue
The interrupt line (DAT1) is an extra pin comparing to SD memory,
allowing the slave to actively inform the host some events.
It's possible for two ESP32 chips to communicate with each other in
1-bit mode or SPI mode without the DAT1 line by polling the slave's
interrupt registers. But this will increase the CPU load of the host,
and do harm to the response speed to slave events.
This wave generator example does following:
- An analog signal generator.
- Offering four kinds of waveform:
sine, triangle, sawtooth, square.
- Customer can select their expected waveform, frequency, etc. All of them can be configured in menuconfig.
