[Patch v3 0/2] OMAP2PLUS:DSS2: use opt-clocks information from hwmod.

[Sumit Semwal <sumit.semwal@ti.com>]

This series uses information about opt-clocks provided by omap_hwmod framework
to select which of the non-mandatory DSS clocks are available on a given
platform.

A function pointer opt_clock_available is exported via pdata, which checks the
clock roles returned by hwmod database.
In the driver, while doing clk-get, it is checked if as per hwmod a given clock
is an opt-clock or not, and is handled accordingly.

Tested on: OMAP3430sdp

Sumit Semwal (2):
  OMAP2PLUS:DSS2: add opt_clock_available in pdata
  OMAP2PLUS:DSS2: Use opt_clock_available from pdata

changes from v2:
- made oh_core a static variable, looked up only once in omap_display_init.

changes from v1:
- made opt_clock_available a function pointer in the omap_display_platform_data
  to avoid having to copy the opt-clock role names.
