This patch adds minimum required hwmod data (e.g., UARTs) for bootup of
TI81XX devices (currently common data for TI816X and TI814X is added).

Signed-off-by: Hemant Pedanekar <redacted>

I haven't looked at the details yet, but just tried to boot this using
current mainline and it fails.

My first guess is that it appears to be related to a missing clkdm for the
MPU hwmod.

Thanks for the feedback.

I think that the issue is bacause clk_get() on fck_source is failing
as TI816X clock data had different clock source names compared to
OMAP3 (e.g., osc_sys_ck instead of sys_ck). I will update this in next
version.

Actually, I realized also that ti816x doesn't boot on current l-o master
branch, even without this series.

Even after this, the kernel would get stuck at "Calibrating delay loop..."
because a few timer register offsets on TI81XX are different than
OMAP3. 

At least with my tests, it's getting past that and failing here:

The reason seems to be that no hwmods are getting registered at all.

I see there are some patches floating on ML which add reg_map array
(similar to i2c driver) but seems they have not (yet) been
accepted. Any chance that this will get added to kernel?

I'm not sure.  Which series are you referring to?
