ARM: ux500: add CoreSight blocks to DTS file
This registers all the CoreSight blocks on the DB8500 SoC: each core has a PTM (v1.0, r1p0-00rel0) connected, both connected to a funnel (DK-TM908-r0p1-00rel0) which in turn connects to a replicator (DM-TM909-r0p1-00rel0). The replicator has two outputs, port 0 to a TPIU interface and port 1 to an ETB (DK-TM907-r0p3-00rel0). The CoreSight blocks are all clocked by the APEATCLK from the PRCMU and their AHB interconnect is clocked from a separate clock called APETRACECLK. The SoC also has a CTI/CTM block which can be added later as we have upstream support in the CoreSight subsystem. Acked-by: Mathieu Poirier <mathieu.poirier@linaro.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
