Interrupts are enabled at the point where
the DAVINCI_I2C_IVR_REG is read, so unless
an interrupt happened just at that moment,
no interrupt would be pending. Even though
documentation implies you should do this,
I see no reason. If slave support is added,
this read would cause a hard to reproduce bug.

When building as a module, the board support code (which is compiled
in) cannot directly call the driver code (which may be in a module.)

This patch the separates the card-detect IRQ usage into board-specific

platform data.

These changes is the result of the discussion with Paul Walmsley.
His ideas are included into this patch.

Remove DPLL output divider handling from DPLLs and CLKOUTX2 clocks,
and place it into specific DPLL output divider clocks (e.g., dpll3_m2_clk).
omap2_get_dpll_rate() now returns the correct DPLL rate, as represented
by the DPLL's CLKOUT output. Also add MPU and IVA2 subsystem clocks, along
with high-frequency bypass support.

Add support for DPLLs function in locked and bypass clock modes.
