The DMA_MCUX_EDMA_V5 configuration option has been removed and replaced with DMA_MCUX_EDMA_V4, as both versions share the same register layout and can use the same driver implementation. Key changes: - Remove CONFIG_DMA_MCUX_EDMA_V5 Kconfig option - Replace DMA_MCUX_EDMA_V5 conditionals with DMA_MCUX_EDMA_V4 - Remove DMAx_Type typedef, use DMA_Type directly - Update EDMA_HW_TCD macros for V4 to use HAL-provided accessor macros - Add DMA_MCUX_EDMA_DMAMUX Kconfig option to control DMAMUX support based on device tree property - Update device tree binding to add has-dmamux property - Update HAL driver selection to use DMA_MCUX_EDMA_DMAMUX instead of DMA_MCUX_EDMA for DMAMUX component - Add SOC_SERIES_MCXE31X to DMA_MCUX_TEST_SLOT_START configuration - Calculate DMA_TCD_ALIGN_SIZE from edma_tcd_t structure size Signed-off-by: Qiang Zhang <[email protected]>
