[PATCH 5/8] arm64: dts: imx8mm-kontron: Fix CAN SPI clock frequency
From: Frieder Schrempf
Date: Thu Sep 30 2021 - 11:57:14 EST
From: Frieder Schrempf <frieder.schrempf@xxxxxxxxxx>
The MCP2515 can be used with an SPI clock of up to 10 MHz. Set the
limit accordingly to prevent any performance issues caused by the
really low clock speed of 100 kHz.
Fixes: 21c4f45b335f ("arm64: dts: Add the Kontron i.MX8M Mini SoMs and baseboards")
