Subject: [PATCH 10/12] ARM: OMAP3: hwmod data: fix IVA interface clock
Date: Wed, 07 Mar 2012 19:38:39 -0700 [thread overview]
Message-ID: <20120308023839.8205.66682.stgit@dusk> (raw)
In-Reply-To: <20120308023614.8205.78768.stgit@dusk>
The OMAP3 hwmod data listed iva2_ck as an interface clock between the
IVA and L3. This is incorrect. iva2_ck is not an interface clock.
Since it cannot auto-idle, specifying it here prevents the IVA and at
least one of the CORE clockdomains from going idle, which causes PM
problems such as these upon system suspend:
[ 70.626129] Powerdomain (iva2_pwrdm) didn't enter target state 1
[ 70.626190] Powerdomain (core_pwrdm) didn't enter target state 1
Fix by specifying the actual interface clock in the hwmod data.
