I made a somewhat hacky quickfix for beagle. Applying that and the

hear if it has any effect.

Applying those 2 patches doesn't help, still get exactly the same warning.
Find attached my clk_summary (with my hacky patch applied, otherwise I
cannot boot the device)

It looks like the omap36xx version of the omap96m_alwon_fck is modelled
improperly in the dts files. I don't have access to omap36xx hardware
myself, but give a try for the following patch:

Subject: [PATCH] ARM: dts: omap36xx: fix omap96m_alwon_fck
OMAP36xx has different hardware implementation for the omap96m_alwon_fck
compared to other OMAP3 variants. Reflect this properly in the dts file.
