Meta:
Roadmap id: CARD-114
Headline: Ux500 core and drivers now use common clk infrastructure
Acceptance: ux500 common clock code merged into torvalds/linux-2.6.git

[jakub-pavelek 2013-02-05] Moving from 3.8 to 3.9 kernel release.
[jakub-pavelek 2013-02-25] we have everything but abx500 in 3.9, and that last driver will be 3.10. Moving from 3.9 to 3.10
[jakub-pavelek 2013-04-08] As linusw says, the remaining abx500 clock work is a follow-up already, like full support for all clocks and some hardening of the framework. The prerequisites for singe zImage were fulfilled already. Moving from Essential to lower priority.

[arnd-arndb 2013-05-08] all essential parts are merged into 3.10-rc1 as of 6fa52ed33bea997374a88dbacbba5bf8c7ac4fef
