Hi,
I have discovered a bug in the cpuidle code for the OMAP-L13x (da8xx)
platform.
In the state described as "WFI and DDR Self-Refresh", the code is
actually putting the DDR into the "Power Down" mode which is not the
same as self-refresh.
So the description string should read "WFI and DDR Power Down".
Putting the DDR into self-refresh and subsequently gating the clocks for
greater power savings, requires significantly more work (Refer to
Section 2.16 OMAP-L1x DDR2/mDDR Memory Controller User's Guide).
cheers,
James
