PATCH 1/1 ARM: dts: imx6q: Use correct SDMA script for SPI5 core
Quoted 8 lines · Sean Nyekjaer
According to the reference manual the
shp_2_mcu/mcu_2_shpscripts must be used for devices connected through the SPBA.This fixes an issue we saw with DMA transfers. Sometimes the SPI controller RX FIFO was not empty after a DMA transfer and the driver got stuck in the next PIO transfer when it read one word more than expected.
