This patch series, intended for 2.6.38:
- includes Rajendra's powerdomain changes to add OMAP4 support;
- allocates static powerdomain and clockdomain data in C files
rather than header files (long overdue);
- begins the process of cleaning up mach-omap2/prcm.c;
- splits the OMAP4 PRCM header files into per-hwmod or per-PRCM partition
files;
- renames the OMAP4 PRCM *_MOD macros to *_INST so the names actually have
some meaning in regards to the hardware;
- moves the OMAP2/3-specific PRCM functions into OMAP2/3-specific files, in
preparation for creating OMAP4-specific versions;
- moves the CM context save/restore file to CM-specific code, and
removes the PRM context save/restore code - which should save a few
microseconds in the off-mode save/restore path.
The series applies on top of v2.6.37-rc4. It is available via git from
git://git.pwsan.com/linux-2.6 in the branch 'pwrdm_prcm_a_2.6.38'.
Kevin, I'd appreciate review and acks, if appropriate, on the patches
that touch code that you maintain. Rajendra, Santosh, I've made some
minor changes to your patches; if you have the chance you might want
to take a look and comment if necessary.
Boot-tested on N800, OMAP35xx Beagle, and OMAP4430ES2 Panda.
A followup series that builds on this one will be sent tomorrow.
- Paul
