Trying to just send something to the SPI, but it fails with: tegra-dvfs: rate 408000000 too high for dvfs on sbc1 spi-tegra114 7000d400.spi: clk_prepare failed: -22 spi_master spi0: Failed to power device: -22 Currently using tegra210-p3448-0002-p3449-0000-b00.dtb and L4T R32.4.3 Previous tes…

Please try to reduce the “spi-max-frequency” in device tree to check.
