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:

* 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
