If anyone has any objections, please let me know. ------------------ From: Tim Harvey commit 0bdaca0922175478ddeadf8e515faa5269f6fae6 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.
