On the Freescale P1022DS reference board, the SSI audio controller is connected in "asynchronous" mode to the codec's clocks, so the device tree needs an "fsl,ssi-asynchronous" property. Also remove the clock-frequency property from the wm8776 node, because the clock is enabled only if U-Boot enables it, and U-Boot will set the property if the clock is enabled. A future version of the P1022DS audio driver will configure the clock itself, but for now, the driver should not be told that the clock is running when it isn't. Signed-off-by: Timur Tabi <timur@freescale.com> --- Without this patch, audio is broken on the P1022DS. I don't know why I missed this on the initial version of the device tree. I will also post this patch for the -stable trees. arch/powerpc/boot/dts/p1022ds.dts | 7 +++++-- 1 files changed, 5 insertions(+), 2 deletions(-)
