I did the following build tests on [1]:
-> Native omap2plus build
-> Omap2 only build
-> Omap3 only build
-> Omap4 only build
-> Omap5 only build
-> AM33XX only build.
-> omap1_defconfig
And also did functional testing on [2] where omap5_pm branch[1] is merged.
On OMAP5430 EVM: Suspend to RAM (UART wakeup)
CPU_IDLE
On OMAP4430 SDP: Suspend to RAM (UART wakeup)
CPU_IDLE
Note:
1) Disabled SMP for doing build test on Omap2/3 only builds.
2) If we enable CPU_IDLE on OMAP4430, debug message flood from
reset_ctrl_regs() will appear.
As this is already disussed and a patch is already sent on Mainline
Will get more info on this here[3]
