| Subject: arm64: dts: imx8mn: Change SDMA1 ahb clock for imx8mn |
| |
| From: Adam Ford <aford173@gmail.com> |
| |
| commit 15ddc3e17aec0de4c69d595b873e184432b9791d 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. |
| |
| Fixes: 6c3debcbae47 ("arm64: dts: freescale: Add i.MX8MN dtsi support") |
