The ``adc_digi_config_t`` struct is modified on esp32c3: configuration
of clock divider factors are not provided anymore. The SARADC sampling
frequency is provided instead. In this way, we can handle the frequency
limit better.
The way the adc_dma_demo data was formatted caused it go get parsed as markdown syntax.
Changed it be more "human" readable as well as put all ADC examples in a common folder
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
During HAL layer refactoring and new chip bringup, we have several
caps.h for each part, to reduce the conflicts to minimum. But this is
The capabilities headers will be relataive stable once completely
written (maybe after the featues are supported by drivers).
Now ESP32 and ESP32-S2 drivers are relative stable, making it a good
time to combine all these caps.h into one soc_caps.h
This cleanup also move HAL config and pin config into separated files,
to make the responsibilities of these headers more clear. This is
helpful for the stabilities of soc_caps.h because we want to make it
public some day.
mcpwm_basic_config example calculates period incorrectly in high
frequency. The period calculation will move to ISR and the method of
calculation will be changed.
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.

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`.

* Delete the relevant codes of PDM of ESP32-S2 ll layer.
* 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.
The following commit refactors the CAN driver such that
it is split into HAL and Lowlevel layers. The following
changes have also been made:
- Added bit field members to can_message_t as alternative
to message flags. Updated examples and docs accordingly
- Register field names and fields of can_dev_t updated
1. add hal and low-level layer for timer group
2. add callback functions to handle interrupt
3. add timer deinit function
4. add timer spinlock take function
This commit fixes multiple bugs caused by incorrect calls to
can_enter_reset_mode() and can_exit_reset_mode. Example test
scripts also updated to match new runners.
