Commit 17b7e7d335 ("ARM: OMAP4:
clock/hwmod data: start to remove some IP block control "clocks"")
introduced a regression preventing the L3INIT clockdomain of OMAP4
systems from entering idle. This in turn prevented these systems from
entering full chip clock-stop.
The regression was caused by the incorrect removal of a so-called
"optional functional clock" from the OMAP4 clock data. This wasn't
caught for two reasons. First, I missed the retention entry failure
in the branch test logs:
http://www.pwsan.com/omap/testlogs/cleanup_a_3.9/20130126014242/pm/4460pandaes/4460pandaes_log.txt
Second, the integration data for the OCP2SCP PHY IP block, added by
commit 0c6688753f ("ARM: OMAP4: hwmod
data: add remaining USB-related IP blocks"), should have associated this
clock with the IP block, but did not.
Fix by adding back the so-called "optional" functional clock to the
clock data, and by linking that clock to the OCP2SCP PHY IP block
integration hwmod data.
