I'd like to mention that this issue has been caught while upgrading
custom Linux Kernel 3.4 to the last Stable Kernel linux-3.4.y.
So, the same OMAP4+ functionality can be broken in all Stable trees
where commit "ARM: OMAP2+: hwmod: Fix SOFTRESET logic" was merged to.
On OMAP4+ we should always try to wait until IP reset is finished before proceed.

I'd like to mention that this issue has been caught while upgrading
custom Linux Kernel 3.4 to the last Stable Kernel linux-3.4.y.
So, the same OMAP4+ functionality can be broken in all Stable trees
where commit "ARM: OMAP2+: hwmod: Fix SOFTRESET logic" was merged to.
On OMAP4+ we should always try to wait until IP reset is finished before proceed.

I'd like to mention that this issue has been caught while upgrading

So, the same OMAP4+ functionality can be broken in all Stable trees

On OMAP4+ we should always try to wait until IP reset is finished before proceed.
