[U-Boot-Users] [PATCH] [ADS5121] Device tree updates

[John Rigby]

Changes to match 5121 device tree going mainline in 2.6.25.

Change OF_SOC from "soc5121" to plain "soc".
Remove unneeded "ref-frequency" fixups.
Remove "address" enetaddr fixup.

Add bus-frequency fixup for old OF_SOC so old
kernels with old device trees will work with new
u-boot with 66MHz IPS clock

This should be looked up by compatible, not by path.

This should be done with aliases.
