Subject: [RFC 0/5] ARM: Add Cross Trigger Interface driver
Date: Wed, 12 Dec 2012 15:43:03 -0600	[thread overview]
Message-ID: <1355348588-22318-1-git-send-email-jon-hunter@ti.com> (raw)

Adds AMBA driver for ARM Coresight Cross Trigger Interface (CTI) driver
and device-tree binding for CTI module.

I have tested the driver on an OMAP4430 device and include the relevant
patches needed to enable CTI on OMAP4 devices for reference.

I would like to get some feedback on the binding, CTI APIs and usage of
the APB clock for OMAP4. I have seen that there has been some recent
discussion around adding other coresight drivers for ARM devices [1]
and so it would be also good to align on the appropriate location for
coresight drivers in general.

This series is based on the ARM-SOC for-next branch and Will Deacon's
patch for the CTI lock registers [2].
