X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=2c981e325f0c18e24ce252f16f5018b9ee805212;p=openwrt%2Fstaging%2Fblogic.git

MIPS: CPC: Use common CPS accessor generation macros

Switch the MIPS Cluster Power Controller (CPC) accessor functions to be
generated by the new common Coherent Processing System (CPS) macros
shared with the Coherence Manager (CM).
