If you haven't already resolved this, could you enable verbose debug
info (or use gdb) to get the line number?

I don't see the WARNING when booting mpc8379rdb with SPI enabled (though
I do see the master is unqueued message).  I don't have easy access to
an mpc8313erdb to test on.

spi, spi_fsl-spi.c not working?

2014-07-17 Thread Heiko Schocher 

Hello all,

I just tried a mpc83xx based board (similiar to the mpc8313erdb)
with linux v3.16-rc4 using the drivers/spi/spi-fsl-spi.c driver.

reg = 0x7000 0x1000;

mode = cpu;
};

Did someone detected such a problem with this driver?

Is it maybe the missing support for the SPI subsystem's queue SPI messages?

Any hints?

Thanks!

It shouldn't be that, that's still optional (sadly).
