- New drivers: - SD SPI - spi_peripheral - touch_placeholder - display_placeholder - Devicetree compiler: - Implement phandle-arrays - Implement device addresses - Add placeholder drivers to all devices with a SPI display - SPI driver: add `cs-pins` and set them to high on driver start - FileSystem: add `file_system_set_owner()` and `file_system_get_owner()` - File locking is now checking if the related `FileSystem` is part of a shared SPI bus - Add `device_get_child_count()` - SDMMC driver: Remove default of `slot` value - Fix for Crowpanel Basic 3.5" display (add delay to booting) - Fix for LilyGO T-HMI SD card mounting (delayed mounting by disabling it initially in the dts)
