From mboxrd@z Thu Jan 1 00:00:00 1970 From: b-cousson@ti.com (Benoit Cousson) Date: Thu, 18 Oct 2012 15:39:05 +0200 Subject: [PATCH] ARM: OMAP2+: clockdomain: Fix OMAP4 ISS clk domain to support only SWSUP Message-ID: <50800679.2030202@ti.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org From: Miguel Vadillo Since CAM domain (ISS) has no module wake-up dependency with any other clock domain of the device and the dynamic dependency from L3_main_2 is always disabled, the domain needs to be in force wakeup in order to be able to access it for configure (sysconfig) it or use it. Also since there is no clock in the domain managed automatically by the hardware, there is no use to configure automatic clock domain transition. SW should keep the SW_WKUP domain transition as long as a module in the domain is required to be functional. Signed-off-by: Miguel Vadillo Signed-off-by: Benoit Cousson --- Hi Tony, Here is a fix that Miguel sent me some time back and that I forgot until I face the crash again while trying to enable the ISS for test.
