X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1d4bed0d9cb25ea40852a782973b821af520f73a;p=thirdparty%2Flinux.git

ARM: dts: renesas: r8a7740: Add ZT/ZTR trace clocks

Add ZT trace bus and ZTR trace clocks on R-Mobile A1.
These clocks supply the coresight tracing modules, PTM, TPIU, ETB and
replicator.  Without these clock, coresight tracing can not be operated.
