On OMAP4, the PRCM recommended sequence for enabling
a module after power-on-reset is
-1- Force clkdm to SW_WKUP
-2- Configure desired module mode to "enable" or "auto"
-3- Wait for the desired module idle status to be FUNC
-4- Program clkdm in HW_AUTO(if supported)
This sequence applies to all older OMAPs' as well,
however since they use autodeps, it makes sure that
no clkdm is in IDLE, and hence not requiring a force
SW_WKUP when a module is being enabled.
This patch is currently breaking boot on OMAP4430 ES2.0 Pandaboard,
so I've dropped it from the integration branch until it can be
debugged. Could you check it, please?
It's also breaking boot on OMAP35xx BeagleBoard rev C2. The kernel
boot messages are below - omap2plus_defconfig + DEBUG_LL. Reverting
the patch fixes it. Could you please take a look?
I got hold of a Beagle, a sticker on which says rev C1D.
Not sure if there is a better way to identify the rev, but
this one seems to boot fine for me even with this patch.
I just applied this one patch on top of the the tag
'integration-2.6.39-20110310-008' of git://git.pwsan.com/linux-
integration.
Would a board rev make a difference?
