This commit updates the common-source integration for Xtensa-based
Espressif devices (ESP32, ESP32-S2, and ESP32-S3). This is part of a larger
common-source update split by architecture for better maintainability.
Major components updated:
- IRQ allocator refactoring with intr_alloc integration
- Common-source drivers (GPIO, RMT, I2C, SPI, UART, etc.)
- Espressif components upgrade to release/master.b-test
- Peripheral drivers (ADC, PWM, LEDC, MCPWM, PCNT, Temperature Sensor, etc.)
- Wireless adapters (Wi-Fi and BLE)
- esp_timer migration to the common-source path for Xtensa devices
- Common-source power management implementation (auto-sleep and wakeup paths)
- Board defconfigs for all Xtensa Espressif boards
- SMP support improvements for ESP32-S3
- Critical section handling improvements
Key architectural changes:
- IRQ Allocator: The new interrupt allocator enables multiple mapping
options from interrupt sources to CPU interrupts, providing flexibility
required by modern peripherals. Although this introduces breaking changes
to the interrupt handling API, the required ARCH_MINIMAL_VECTORTABLE
Kconfig option is explicitly checked during startup to ensure proper
configuration. This validation prevents runtime issues from configuration
mismatches.
- Xtensa-specific interrupt handling via esp_xtensa_intr.c providing
NuttX-native implementations of xt_ints_on/off and interrupt handlers,
avoiding conflicts with NuttX's core Xtensa macros.
- Timer/RTC unification: ESP32/ESP32-S2/ESP32-S3 move from chip-specific
RTC/RT-timer code to common-source Espressif integration, including
esp_timer_adapter/esp_rtc paths and the required bringup/defconfig updates.
- Power management consolidation: Xtensa PM follows the common-source
implementation, including common-source auto-sleep behavior, UART/Wi-Fi
wakeup coordination, and tickless-safe sleep flow compatibility.
Note: This is a large commit to maintain bisectability. Breaking the
changes into smaller commits would result in non-building intermediate
states across the common-source infrastructure update.
Tested configurations:
- All defconfigs were tested, including `ostest`.

This commit implements the common RMT driver (already available for
the other Espressif's xtensa-based devices) for ESP32.
This allows us to have a proper separation between the lower and
upper-half drivers and use the 'ws2812' example to drive WS2812 RGB
LEDs.
Enable with ./tools/configure.sh -l esp32-devkitc:dac
DAC channel 0 = GPIO 25
DAC channel 1 = GPIO 26
default path: /dev/dac0
Resolution 8 bits = values 0~255
Voltage: 0~Vref
The reference voltage 'Vref' here is input from the pin VDD3P3_RTC
which ideally equals to the power supply VDD (3.3V).
The RMT (Remote Control) character driver allows to use the RMT
peripheral (usually, a one-wire peripheral dedicated to driving
IR remote control) as a character driver.
Please note that this perpiheral depends on the lower-half specific
driver implementation.
This commit provides an interface to register ISRs that run from
IRAM and keeps track of the non-IRAM interrupts. It enables, for
instance, to avoid disabling all the interrupts during a SPI flash
operation: IRAM-enabled ISRs are, then, able to run during these
operations.
It also makes the code look more similar to the ESP32-S3 SPI flash
implementation by creating a common `esp32_spiflash_init` that is
responsible to create the SPI flash operation tasks. The function
intended to initialize the SPI flash partions was, then, renamed to
`board_spiflash_init`.

As ESP32 has 2 I2C interfaces and BMP180 is a I2C sensor, the criterias to use BMP180 in I2C0 or I2C1 are:
1- First, bring-up routines search for BMP180 in I2C0.
If BMP180 is found in I2C0, then /dev/press0 is created.
2- If BMP180 cannot be registered in I2C0, bring-up routines search for it in I2C1.
If BMP180 is found in I2C1, then /dev/press0 is created.
It means only one BMP180 could be suported in Nuttx. In my tests I've observed
that BMP180 example application doesn't seem to work with /dev/press1 BMP180 device,
therefore even BMP180 is found in I2C1, it'll be registered as /dev/press0 device.
It was missing and it wasn't possible to enable I2C (0 and/or 1)
before this fix.
To sum up, this fix implements a I2C register function in ESP32
bring-up routines (esp32_bringup.c) and call if for I2C0 and/or
I2C1 during ESP32 bringup (these function callings are conditioned
by CONFIG_ESP32_I2C (to check if I2C support has been configured),
CONFIG_ESP32_I2C0 (to check if I2C0 support has been configured)
and CONFIG_ESP32_I2C1 (to check if I2C1 support has been configured).
Once this fix is implemented, /dev/i2c0 and/or /dev/i2c1 interfaces
become available and work fine.
