AM1705 spidev1.4 and spidev1.5 accesses hang processor

Hi all,

I have need to create 6 spi devices on bus1 of our custom board using am1705 SoC. I have successfully created the spidevs and installed the proper structures for using gpio chip selects with each one. There are also two such spidevs on bus 0 along with the spi flash similar to evm board.

The problem I am seeing is that I can successfully talk to all spi devices except spidev1.4 and spidev1.5. The processor hangs and must be rebooted. To prove these particular devices are not the issue I moved them up in the modalias list of spi_board_info so that they were spidev1.2 and 1.3 and the spidev_test did not hang. I also verified with a o-scope that the cs pin did fire at the device.

Is there a bug here, or a limit on the number of devices on each spi bus?

thanks as always,

Dan
