Subject: [PATCH C 00/13] OMAP clock, C of F: DPLL updates

This series is the third of six to bring the mainline kernel OMAP
clock code up-to-date with the linux-omap tree.

Major changes in this series:

- Fix DPLL jitter compensation (FREQSEL).
- Calculate correct rates when DPLL is in bypass.
- Remove the virtual "bypass clocks."
- Optimize DPLL rate rounding algorithm.

Some patches have been "compressed" together, as requested by rmk -
original commit IDs are in the patch descriptions.

Compile-tested on OSK5912 (OMAP1), H4 and 2430SDP (OMAP2), and
BeagleBoard (OMAP3).  Boot-tested on 2430SDP and BeagleBoard.

Applies on top of series B, posted earlier.

Paul Walmsley (12):
      OMAP3 clock: disable DPLL autoidle while waiting for DPLL to lock
      OMAP3 clock: avoid invalid FREQSEL values during DPLL rate rounding
      OMAP3 clock: optimize DPLL rate rounding algorithm
      OMAP3 clock: remove unnecessary dpll_data dereferences
      OMAP3 clock: fix non-CORE DPLL rate assignment bugs
      OMAP3 clock: put DPLL into bypass if bypass rate = clk->rate, not hardware rate
      OMAP3 clock: recalculate DPLL subtree after bypass entry/exit
      OMAP3 clock: DPLLs should enter bypass if new rate is sys_ck
      OMAP3 clock: note the bypass source clock for DPLLs
      OMAP3 clock: convert dpll_data.idlest_bit to idlest_mask
      OMAP3 clock: DPLL{1,2}_FCLK clksel can divide by 4
      OMAP3 clock: fix DPLL jitter correction and rate programming
