Subject: [PM-SR] [PATCH] OMAP: PM: Remove the usage of vdd id's.
Date: Thu, 24 Jun 2010 20:32:48 +0530 [thread overview]
Message-ID: <1277391768-3361-1-git-send-email-thara@ti.com> (raw)
This patch removes the usage of vdd and sr id alltogether.
This is achieved by introducing a separte voltage domain per
VDD and hooking this up with the voltage and smartreflex
internal info structure. Any user of voltage or smartreflex layer
should call into omap_volt_domain_get to get the voltage
domain handle and make use of this to call into the various
exported API's.
These changes should be part of V2 of the sr/voltage series
instead of being a separate patch in itself.
