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
If bluetooth modem sleep is enabled and "External 32kHz crystal" is used as bluetooth sleep clock, the power management lock "ESP_PM_NO_LIGHT_SLEEP" in bluetooth is released for the periods of time when Bluetooth enters modem sleep. In this case automatic light sleep is allowed.
This commit does the following
- Add power management lock to CAN driver so that APB frequency does not change
whilst CAN driver is in use
- Fix incorrect flag in can_transmit()
- Refactor can_driver_install() and can_driver_uninstall() so that critical sections
are shorter
- Fix CAN gpio configuration bug on RX pin. Closes#2302
- Add docs about multiple ID configuration and fix example links
