From mboxrd@z Thu Jan 1 00:00:00 1970 From: t-kristo@ti.com (Tero Kristo) Date: Mon, 14 May 2012 13:03:10 +0300 Subject: [PATCHv5 2/8] TEMP: ARM: OMAP4: hwmod_data: Do not get DSP out of reset at boot time In-Reply-To: <1336989796-26594-1-git-send-email-t-kristo@ti.com> References: <1336989796-26594-1-git-send-email-t-kristo@ti.com> Message-ID: <1336989796-26594-3-git-send-email-t-kristo@ti.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org From: Rajendra Nayak With no driver handling DSP, if brought out of reset, it stays active and does not assert standby. This leads to IVAHD powerdomain not transitioning and hence preventing chip retention. This patch is no longer needed once Paul's powerdomain fixes are merged: http://marc.info/?l=linux-omap&m=133040749621183&w=2 Just provided for testing purposes.
