Hello,
This is version 2 of the clock updates series sent earlier. Changes
in v2:
1. Missing structure documentation for struct clk_child added
2. .clk_register function pointer added to struct clk_functions;
OMAP2/3 clock code now does clock->clockdomain association there
Revised summary below. Happy new year, everyone.

------------------
Hello,
this 23-patch series updates the OMAP1/2/3 clock code. Highlights:
- Rate recalculation functions are now no longer responsible for
rate propagation - now handled by plat-omap/clock.c (patches 2, 3,
4)
- Parent-to-child traversals of the clock tree are now much faster -
these occur during rate propagation and clock notifiers (patch 5)
- Many superfluous clock flags have been dropped (patches 6, 7, 8, 9)
- struct clk has been streamlined by removing unused members and
rearranging the structure to reduce padding (patches 10, 11)
- MPU barriers have been either removed or converted to OCP barriers
(patches 12, 13, 14)
- clk_get_usecount() has been dropped (patch 15)
- OMAP clock code can now specify an OMAP chip family-specific
clk_enable() function - used on OMAP2/3 (patch 16)
- omap2_clk_enable() has been overhauled: two bugs were fixed and
the function body itself is now understandable (patches 17, 18, 19,
20, 21)
- Unnecessary custom clocks in smartreflex.c have been removed
(patch 23)
- Miscellaneous bug fixes (patches 1, 22)
Compile-tested on OMAP1. Boot-tested on N800 and 3430SDP GP ES2.1.
