Kumar Gala 43a7d26603 drivers: entropy: replace CONFIG_ENTROPY_NAME with DT macro
Replace CONFIG_ENTROPY_NAME with DT_CHOSEN_ZEPHYR_ENTROPY_LABEL.  We now
set zephyr,entropy in the chosen node of the device tree to the entropy
device.

This allows us to remove CONFIG_ENTROPY_NAME from dts_fixup.h.  Also
remove any other stale ENTROPY related defines in dts_fixup.h files.

Peter Bigot 10075991cc drivers: gpio_esp32: add support for pin validation
Add a config structure for each port and use the devicetree GPIO pin
count to initialize it.  Simplify device initialization by using
instance number as only variation point.

Mohamed ElShahawi 2d2f4de5b8 drivers: watchdog: esp32: Add Watchdog Device tree support
- Add WDT(0,1) to esp32.dtsi
- Extend the module to be able to use WDT(0,1)
- Some minor refactoring due to usage of device tree

Tests:
- samples/drivers/watchdog
- tests/drivers/watchdog/wdt_basic_api

Note:
- timer module interrupt registers shall be removed when
timer driver implemented.

Mohamed ElShahawi 0705be344c drivers: esp32: UART Fix yaml/dts binding name
replace "xtensa" with "espressif", as the latter is the correct
vendor name.

Mohamed ElShahawi 2d035c4191 drivers: esp32: Add UART Driver with FIFO/Interrupt support
- Fixes #3981
- Implement UART Polling functions
- Implement UART Interrupt APIs
- Remove dependency on esp32_rom_uart_xxx functions
- Update Device tree with UART addresses and pin config
- Update ESP32 UART KConfig

Notes about implementation:
- Interrupts now defined as a local macros, and should be removed
later on, when interrupts for esp32 are supported in dts

- Threshold interrupts are used for TX/RX
- Reseting FIFOs using _RST bit will corrupt FIFO of UART2 when used for
UART1 and vice-versa, so a generic way is used for all three UARTs

- Old Silicon rev is not supported

Piotr Zięcik 7d56fc35fd dts: Add information about CPU frequency to the cpu nodes
This commit adds 'clock-frequency' property to the cpu nodes.
The clock frequency specified in the added property is used
during platform configuration. Examples:

- The SWO logger uses clock frequency to configure SWO output.
- Plenty of platforms need CPU clock specified for their HAL.
- Most of devices with USB needs information about CPU clock
  in order to configure USB clock source.
