## Summary Implement 3-wire 9-bit SPI for LCD's SPIIF and therefore for ILI9341. This is needed for communication with ILI9341 displays over 3-wire 9-bit SPI. ## Impact When appropriate option is selected in menuconfig, it is possible to communicate with supported display over 3-wire 9-bit SPI. ## Testing I have used changes in this PR along with the BSP for our arm-based board, enabled LVGL in menuconfig, and run `lvgldemo` command. I compiled the code with the option switched off. Host machine: `Linux yahiko 6.12.57+deb13-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.12.57-1 (2025-11-05) x86_64 GNU/Linux` Board: Our Kinetis K60-based board with Densitron DET24QVF2H-C LCD display that supports ILI9341 over 3-wire 9-bit SPI. I run `lvgldemo` command. -- This is an automated message from the Apache Git Service. To respond to the message, please log on to GitHub and use the URL above to go to the specific comment.
