Merge tag 'omap-for-v3.9/clock-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into late/omap
From Tony Lindgren:
omap clock changes via Paul Walmsley <paul@pwsan.com>:
Some miscellaneous OMAP2+ clock fixes, mostly related to the recent
common clock framework conversion.
Basic test logs are available here:
http://www.pwsan.com/omap/testlogs/clock_devel_a_3.9/20130208120108/
* tag 'omap-for-v3.9/clock-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap:
ARM: OMAP4: clock data: Add missing clkdm association for dpll_usb
ARM: OMAP AM33XX: clock data: SET_RATE_PARENT in lcd path
ARM: OMAP2+: clock data: add DEFINE_STRUCT_CLK_FLAGS helper
ARM: OMAP2+: dpll: am335x - avoid freqsel
omap3isp: Set cam_mclk rate directly
ARM: OMAP3: clock: Back-propagate rate change from cam_mclk to dpll4_m5
