Subject: [PATCH 05/27] omap2 clock: rename, add comment to omap2_mpu_recalc()
Date: Mon, 27 Aug 2007 02:39:01 -0600 [thread overview]
Message-ID: <20070827084122.544259482@pwsan.com> (raw)
In-Reply-To: 20070827083856.549249288@pwsan.com
[-- Attachment #1: clarify_omap2_mpu_recalc.patch --]
[-- Type: text/plain, Size: 2251 bytes --]
omap2_mpu_recalc() actually just looks up what the MPU speed 'should'
currently be from the current virt_prcm_set rate set, rather than reporting
the actual hardware settings. Clarify this by renaming it to
omap2_table_mpu_recalc() and adding some comments.
