## Summary <!-- This field should contain a summary of the changes. It will be pre-filled with the commit's message and descriptions. Adjust it accordingly --> * Documentation: update esp32p4-tab5 with LCD and touch info Adds documentation entries to the tab5 board, mentioning the new defconfigs and updates support features. * boards/risc-v: add LVGL examples on esp32p4-tab5 Adds two examples on esp32p4-tab5 that use LCD and touchscreen. Both redirect the serial console to UART0 instead of USB. * board/risc-v: touchscreen support on esp32p4-tab5 Adds support for ST7123 touchscreen controller on esp32p4-tab5. Includes new KConfig option and additions to hmi_power source. * boards/risc-v: LCD support on esp32p4-tab5 Adds support for st7121 and st7123 variants for LCD support on the esp32p4-tab5 board. Includes power management though IO expander under 'hmi_power' and new board KConfig options. * boards/risc-v: support pio4ioe IO Expander on esp32p4-tab5 Adds support for bringup of the two IO Expanders available on the esp32p4-tab5 board. Those IO Expanders allow for control of many peripherals such as radio, camera, display and touch. * arch/risc-v: MIPI-DSI support for Espressif devices Adds lowerhalf MIPI DSI driver for RISC-V Espressif devices, including KConfig options for LDO and MIPI_DSI. In summary, this PR adds the following: - Display + touchscreen support on `esp32p4-tab5` - PI4IOE expanders - ST7121/ST7123 MIPI-DSI LCD with framebuffer - ST7123 touch and power sequencing - `lvgl_demo`/`lvgl_term` defconfigs - update the board/platform docs accordingly, without changing default configs or breaking other hardware. ## Impact <!-- Please fill the following sections with YES/NO and provide a brief explanation --> Impact on user: Yes, M5Stack Tab5 board can now enable board HMI features that were not available before: PI4IOE IO expanders, MIPI-DSI LCD (/dev/fb0 with ST7121 or ST7123), ST7123 touchscreen, and new LVGL configs (`lvgl_demo`, `lvgl_term`). Impact on build: Yes. Board-only build changes: new Kconfig options (ESP32P4_TAB5_*), additions to in Make.defs/CMakeLists.txt, and two new defconfigs. No core toolchain or global build-system changes. Enabling LCD/touch pulls in I2C, IO expander, MIPI-DSI, framebuffer, and (for the demos) LVGL/graphics dependencies. Impact on hardware: Only affects `esp32p4` devices and the `tab5` board. Impact on documentation: Yes, updates `esp32p4-tab5` documents (supported features, I2C map, lvgl_demo/lvgl_term) and marks MIPI DSI as supported in `esp32p4` page. Impact on security: No. Impact on compatibility: No. ## Testing The target board is the `esp32p4-tab5`. Build each of the new configs: `lvgl_demo` and `lvgl_term`. ### Building - `./tools/configure.sh -S esp32p4-tab5:lvgl_term` - or `./tools/configure.sh -S esp32p4-tab5:lvgl_demo` - Make and flash ### Running Important: this board routes the serial console to UART0 instead of the USB Serial device, due to an issue on the USB-Serial driver. ### Results Link with working videos: [Imgur](https://imgur.com/a/nuttx-m5stack-tab5-display-touch-XxGUThD) - Testing nximage splash screen <img width="50%" alt="image" src="https://github.com/user-attachments/assets/1b9a0bc9-d3ae-41fb-bff6-d385c01dc577"; /> -- This is an automated message from the Apache Git Service.
