Re: spi, spi_fsl-spi.c not working?

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.
DT nodes for spi are the same as in arch/powerpc/boot/dts/mpc8313erdb.dts:

                 spi@7000 {
                         cell-index = <0>;
                         compatible = "fsl,spi";
                         reg = <0x7000 0x1000>;
                         interrupts = <16 0x8>;
                         interrupt-parent = <&ipic>;
                         mode = "cpu";
                 };

Bootlog shows:

[    1.341411] fsl_spi f0007000.spi: master is unqueued, this is deprecated
[    1.554405] ------------[ cut here ]------------
[    1.559080] WARNING: at c023a958 [verbose debug info unavailable]

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.
