[omap3isp RFC][RESEND PATCH v2 0/4] Improve inter subdev interaction



These are some patches to make these operations more generic:
- Clock control is being controlled in a very crude manner by
  subdevices, it should be centralized in isp.c.
- LSC prefetch wait check is reading a main ISP register, so move
  it to isp.c
- Abstract SBL busy check: we don't want a submodule thinkering
  with main ISP registers. That should be done in the main isp.c

Also, remove main ISP register dump from CSI2 specific dump. We
should be using isp_print_status if we'll like to know main ISP

Comments are welcome. More cleanups for better subdevice isolation
are on the way.


- Improved logic in isp subdevs clock control (Thanks David Cohen)
- Renamed ispccdc_lsc_wait_prefetch -> isp_ccdc_* to be clear on
  function declaration new location (isp.c) (Thanks David and Laurent)

- Initial version

Sergio Aguirre (4):
  omap3isp: Abstract isp subdevs clock control
  omap3isp: Move CCDC LSC prefetch wait to main isp code
  omap3isp: sbl: Abstract SBL busy check
  omap3isp: csi2: Don't dump ISP main registers
