If anyone has any objections, please let me know. ------------------ From: Tim Harvey commit 528e2d3125ad8d783e922033a0a8e2adb17b400e upstream. The IMX8MPDS Table 37 [1] shows that the max SPI master read frequency depends on the pins the interface is muxed behind with ECSPI2 muxed behind ECSPI2 supporting up to 25MHz. Adjust the spi-max-frequency based on these findings.
