Add support for ST7796 TFT LCD controller (320x480). The driver
implements the NuttX framebuffer interface for SPI-connected displays.
Features:
- SPI interface with CONFIG_SPI_CMDDATA for D/C pin control;
- RGB565 (16-bit) and RGB666 (18-bit) color formats;
- Runtime rotation support (0, 90, 180, 270 degrees) via MADCTL;
- Board-provided configuration via st7796_config_s structure;
- Partial screen update via updatearea for efficient rendering;
- Persistent swap buffer to avoid per-frame allocations;
- Proper ST7796S initialization sequence with documented timing;
The driver uses a board-provided configuration structure allowing
flexible setup of resolution, SPI frequency, color depth, and
initial MADCTL value without requiring Kconfig options in the
generic driver.
Architecture changes in this revision as per request:
- Moved internal register commands to .c file (private)
- Moved MADCTL bit definitions to .c file (private)
- Moved struct st7796_cmd_s to .c file (private)
- Converted MADCTL orientation macros to absolute values
- Moved CONFIG_SPI_CMDDATA error check to beginning of file
- Removed duplicated CONFIG_SPI_CMDDATA guards
- Public header contains only board configuration API
- Changed the Kconfig auto-select FB from 'select' to 'depends on'
Tested with LVGL graphics library on STM32H753ZI board (my own port).

- Fix byte count calculation for 16-bit SPI words
using shift-by-1 instead of shift-by-2
- Use word count instead of byte count for DMA

ASF Infrastructure Team has flagged a GitHub Actions workflow policy violation, inside our PR Labeling. We must remove pull_request_target before 6 Apr 2026, or ASF Infra will turn off all GitHub Builds: https://github.com/apache/nuttx/issues/18359
This PR reimplements the PR Labeling with two triggers: pull_request and workflow_run. We no longer need pull_request_target, which is an unsafe trigger and may introduce security vulnerabilities.
GitHub Actions `codelytv/pr-size-labeler` and `actions/labeler` don't work with the pull_request trigger, so we replaced them with our own code. The implementation is explained here: https://github.com/apache/nuttx/issues/18359
### Modified Files
`.github/workflows/labeler.yml`: Changed the (read-write) pull_request_target trigger to (read-only) pull_request trigger. Compute the Size Label (e.g. Size: XS) and Arch Labels (e.g. Arch: arm). Save the PR Labels into a PR Artifact.
`.github/labeler.yml`: Added comment to clarify that NuttX PR Labeler only supports a subset of the `actions/labeler` syntax: `changed-files` and `any-glob-to-any-file`
### New Files
`.github/workflows/pr_labeler.yml`: Contains the workflow_run trigger, which is executed upon completion of the pull_request trigger. Download the PR Labels from the PR Artifact. Write the PR Labels into the PR.

This is the nominal speed according to the TRM, and using higher
root clock gives more frequency selections (possible dividers) for
the SD card clock configuration.

- Change the board's sd-card speed configuration to just specify the wanted frequency
- Calculate the proper divisors in the driver
- If the sd card frequency exceeds 25 MHz, set the card to high-speed mode
This makes it easier to adjust the operating speed of the sd cards and fixes an error
where cards are being operated in standard mode at over 25MHz speeds. If the speed
is higher than 25MHz, the card needs to be set into high-speed mode.

All combinations of CONFIG_IMX9_USDHC_DMA and CONFIG_ARM64_DCACHE_DISABLE
are valid. Only the required alignment of the DMA buffers are different,
If the cache is enabled, cacle-line aligned buffers need to be used.
Otherwise, the USDHC DMA alignment requirement is just 32-bits.

This commit adds support for PlantUML to the Documentation build

track these UML diagrams as images, and we can modify them easily.

Add packed attribute to lzf header structs to prevent the compiler
from optimizing lzf_magic array initialization into wider store
instructions (e.g. st.h), which can cause misaligned access

The internal implementation of `file_mq_receive` did not allow
receiving a message from an interrupt handler. Although it is not
possible to wait for a message in an interrupt context, it is
perfectly possible to retrieve already-existing messages from the
message queue. This commit modifies file_mq_timedreceive_internal
to enable checking the message list and, if no messages exist, it
returns immediately. This enables receiving any existing messages
in an interrupt context.

Fix three issues in the STM32H7 FDCAN SocketCAN driver:
1. Clock configuration: Allow board.h to override STM32_FDCANCLK.
Previously the driver hardcoded STM32_HSE_FREQUENCY, ignoring
any board-specific clock configuration.
2. ILS register bug: Fix putreg32 call that was writing FDCAN_ILS_TCL
constant instead of the computed regval, causing interrupt routing
issues.
3. Extended ID filter size: Increase n_extid from 64 to 128. Despite
the reference manual (RM0433) suggesting 64 max, testing shows
that 128 is required for reliable extended ID frame reception.
With 64, some extended ID frames were silently dropped.
