From mboxrd@z Thu Jan 1 00:00:00 1970 From: linus.walleij@linaro.org (Linus Walleij) Date: Mon, 20 Apr 2015 15:14:04 +0200 Subject: [PATCH 3/5] ARM: ux500: add CoreSight blocks to DTS file Message-ID: <1429535644-9308-1-git-send-email-linus.walleij@linaro.org> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org 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.
