The common ESP board RMT bring-up files are built whenever ESP_RMT is
enabled, but the esp_lirc declarations are only visible when DRIVERS_RC
is enabled.
Guard the esp_lirc header include and esp_lirc_rx_initialize() /
esp_lirc_tx_initialize() calls with CONFIG_DRIVERS_RC so non-RC ESP
configs continue to build while keeping the LIRC registration path for
the rmt configs.

Add documentation for the RC/LIRC character driver subsystem covering

Remove placeholder empty files under drivers/rmt that were left over

Replace the ESP-specific rmtchar upper-half with arch-local esp_lirc
adapters for Xtensa and RISC-V.
This moves the RMT upper-half out of drivers/rmt, registers LIRC
devices from the ESP board bring-up paths, and removes the old common
rmtchar driver and headers.
Also update the ESP Kconfig and build wiring to build esp_lirc when
ESP_RMT and DRIVERS_RC are enabled.
Fixes discovered during hardware validation:
- register TX as /dev/lirc1 so RX and TX do not collide
- parse the RX worker thread argument from the correct argv slot
- keep RX devices from advertising TX capability

For LCD drivers that implement putarea(), use it to copy the entire
rectangle in a single call instead of per-row putrun() calls. This
avoids the per-row overhead of setting the display window
(CASET+RASET over SPI) for every scanline.

Add board-level support for ES7210 4-ch ADC on lckfb-szpi-esp32s3:
- configs/es7210/defconfig: Board configuration with I2C0, I2S0,
ES7210 driver enabled. I2S pins: BCLK=14, DIN=12, MCLK=38, WS=13,
sample rate 48kHz.
- src/esp32s3_board_es7210.c: Board init registering ES7210 on I2C0
bus with I2S0 as audio transport
- src/esp32s3_bringup.c: Call ES7210 board init on startup; skip
generic I2S audio device registration on I2S0 when ES7210 is
enabled to avoid conflicting audio device on the same port
- src/esp32s3-szpi.h: ES7210 I2C address and device path defines
- src/Make.defs: Build integration for CONFIG_AUDIO_ES7210
Tested: 48kHz/2ch/16bit recording on ESP32-S3 (lckfb-szpi N16R8),
verified with nxrecorder and es7210_test.

Add ES7210 audio ADC driver for NuttX implementing the audio
lower-half interface. Supports 4-channel recording via I2S with
configurable sample rate, bit depth, and mic gain.
- drivers/audio/es7210.c: Codec driver using LPWORK for async buffer
management, I2C register access, and NuttX audio buffer management
- drivers/audio/es7210.h: Internal register definitions and macros
- include/nuttx/audio/es7210.h: Public header with platform config
structure and es7210_initialize() API
- drivers/audio/Kconfig, Make.defs, CMakeLists.txt: Build system
integration for CONFIG_AUDIO_ES7210
Key implementation details:
- ES7210_SDP_NORMAL (normal I2S) instead of TDM, matching NuttX
I2S standard Philips mode
- ES7210_ADC_PGA_POWER_ON bit in gain registers REG43-46, required
for analog front-end amplifier power-on
- 50ms startup delay in es7210_start for codec clock stabilization
- I2S_IOCTL(AUDIOIOC_STOP) in es7210_stop to notify I2S layer,
preventing DMA from running without buffers after stop

The I2S BCLK frequency is calculated as:
bclk = sample_rate * total_slot * data_width
Previously, total_slot was always taken from the static config
(esp_i2s0_config / esp_i2s1_config), which is hardcoded to 2.
This is correct for mono and stereo, but wrong for TDM modes
with more than 2 channels (e.g. 4-channel recording with ES7210).
With 4 channels but total_slot=2, the BCLK is only half of what
it should be, causing the actual sample rate to be half of the
requested rate (e.g. requesting 16 kHz actually samples at 8 kHz).
Replace priv->config->total_slot with MAX(priv->channels, 2) in
all three BCLK calculation sites (i2s_check_mclkfrequency and
i2s_set_clock for both master and slave paths). The MIN of 2
preserves the I2S protocol requirement that at least 2 slots
exist even for mono, while correctly scaling for multi-channel
TDM configurations.

Fix multiple bugs in the I2S RX receive path on ESP32-S3 with GDMA:
- Set streaming=true in i2s_rxdma_start so completed buffers are not
incorrectly marked AUDIO_APB_FINAL
- Restore up_enable_irq calls for DMA interrupt after esp_dma_load
resets the channel
- Skip i2s_hal_rx_reset/rx_reset_fifo on ESP32-S3 which clears the
TDM slot configuration set by i2s_configure
- Accept 1-16 RX channels on ESP32-S3 (was limited to 2)
- Add getreg32 read-back after DMA start to flush CPU write buffer
- Auto-stop RX channel when no pending buffers remain, preventing
hardware from running without DMA descriptors after stop
- Remove duplicate return OK in i2s_rxdma_start
- Fix i2s_ll_tx_enable_mono_mode to i2s_ll_rx_enable_mono_mode in
i2s_rxchannels
- Fix tx_slot_cfg.std to rx_slot_cfg.std in RX PCM slot config
- Fix DMA direction, peripheral ID, data_width, rx_start sequencing,
and rx_eof_num word count in RX path
- Fix esp32s3_board_i2s.c I2S port index

Move conn_unlock() after the data event handling in can_callback()
and udp_callback(). Previously, the connection lock was released
immediately after devif_conn_event(), leaving the subsequent
can_data_event()/net_dataevent() and read-ahead buffer operations
unprotected. This could lead to a race condition where another
context modifies the connection state while data is being stored.
Hold the lock until the entire callback processing is complete to
ensure thread safety.

Use static lower-half instances per timer and select the channel
through Kconfig and board data instead of passing runtime PWM
routing into the driver.
This keeps the HT32 PWM support aligned with the existing NuttX

On ESP32-P4 rev < v3, the 768KB HP L2MEM is split into two
non-contiguous regions: sram_low and sram_high. Previously only
sram_low was used for the heap, wasting 384KB of sram_high.

include/cxx contains NuttX's mini C++ ABI shims and must only be added
to the include path when CONFIG_LIBMINIABI is selected. tools/Config.mk
was adding it unconditionally for every non-LIBCXX/non-UCLIBCXX build,
and the platform.cmake files for arm, arm64, risc-v, x86_64 and tricore
were adding it inside the CONFIG_LIBCXXTOOLCHAIN block.
With an unpatched downloaded ARM GNU Toolchain, <cstdlib> uses
newlib's stdlib.h, defining div_t as an anonymous struct. A later
inclusion of NuttX's stdlib.h via <cstdio>->stdio.h->kmalloc.h then
redefines div_t with struct tag div_s, causing a conflicting declaration
error.
Guard the div_t/ldiv_t/lldiv_t definitions in stdlib.h with
redefinitions when a toolchain stdlib.h was already processed.
Also fix lldiv_s members typed as long instead of long long.
