I forgot about that. Well, everything I said is true about the ngpixis, so I guess I should use "ngpixis" instead of just "pixis" here. I'll have to check if the old pixis can be used this way. > >>> Also you need "pixis" on MPC8544DS, MPC8572DS, MPC8536DS. >> >> Ok. >> >>> Also fpga-cpld makes no sense if we keep this.

Is there a name for the CPLD we use on these chips? I'm having a hard time getting proper documentation on the CPLD. York expressed similar frustration. Perhaps these should be called board-control devices. How about fsl,boardcontrol-cpld fsl,boardcontrol-ngpixis fsl,boardcontrol-qixis -- Timur Tabi Linux kernel developer at Freescale _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
