i.MX6Q/D/DL/S/SL CTI trigger mappings

We were looking for the CTI trigger mappings for the i.MX6 family. All of the documentation since the first published seems to have the following instead of the usual (as in i.MX27, i.MX51, i.MX53 for example) tables and descriptions of trigger input and output mapping: Cross-Trigger Interface (CTI)

The Cross-Trigger Interface (CTI) component is provided by ARM. A brief description

of the CTI is provided below.

There are 3 CTIs in the chip's ARM platform. Two are of which, dedicated to each Core,

while the 3rd is used for various other signals routing.

Each of these CTIs has 8 trigger inputs and 8 trigger outputs that connect to logic in the

domain to be debugged or profiled. Each CTI also includes a 4 channel interface to the

CTM (4 inputs and 4 outputs).

For more information, see ../../../block_guide_library/arm_a9/map_arm_a9.xml.


(This is from the IMX6SDLRM.pdf rev 1. 04/2013 but it is persistent across all the i.MX6 family reference manuals). As an example of what I mean, here's a shot of the i.MX51 version of this page:



Any ideas?
