| Subject: [PATCH] arm64: dts: imx8mm: Change SDMA1 ahb clock for imx8mm |
| |
| commit 24a572bf67994223e722cadfe663e15ba221882a upstream. |
| |
| Using SDMA1 with UART1 is causing a "Timeout waiting for CH0" error. |
| This patch changes to ahb clock from SDMA1_ROOT to AHB which |
| fixes the timeout error. |
