[PATCH 0/4] Clockdomains: add OMAP2/3 clockdomain code, link 34xx clocks with clockdomains

[Paul Walmsley <paul@pwsan.com>]

Hello,

this patch series adds a hardware control interface for OMAP2/3
clockdomains.  Also added is clockdomain usecounting of underlying
clocks, so hardware-supervised and software-supervised clockdomain
transitions can occur correctly.  The interface is fully documented in
the code.

24xx clocks are not yet linked with clockdomains. This will be done in
a later patchset.

This series must be applied after the powerdomain series, posted earlier.

Clockdomain code tested on 3430SDP ES2.1; also boot-tested on N800.

Many people at Nokia and TI provided commentary and review during the
development of the clockdomain patches.  Particular help came from (in
alphabetical order): Karthik Dasu, Tony Lindgren, Rajendra Nayak,
Sakari Poussa, Igor Stoppa, and Richard Woodruff.  Jouni Högander
merits special mention; he took the original code and made it do what
it was supposed to do on the hardware, testing and fixing many bugs.


Comments welcome,

- Paul
