Subject: [PATCH 1/4] arm: omap: hwmod: 43xx: add DebugSS hwmod data
Date: Fri, 23 Jan 2015 17:11:41 -0600	[thread overview]
Message-ID: <1422054704-14915-2-git-send-email-balbi@ti.com> (raw)
In-Reply-To: <1422054704-14915-1-git-send-email-balbi@ti.com>

Without hwmod data for DebugSS, performance monitors
have no chance of running on AM43xx devices.
