Subject: [PATCH 0/4] dmaengine: fsl-edma: fix eDMAv4 uart dma loop test failure
Date: Tue, 14 Nov 2023 10:48:20 -0500 [thread overview]
Message-ID: <20231114154824.3617255-1-Frank.Li@nxp.com> (raw)
The commit a725990557e7d ("arm64: dts: imx93: Fix the dmas entries order")
trigger a hidden eDMAv4 hardware limitation.
Some channel require stick to odd number, some require stick to even
number.
This fixes include 3 part.
1. add limitation at eDMA driver.
2. create dt-binding header file to share define between driver and dts
3. add ODD and EVEN requirement for uart driver at dts file.
