Subject: Re: [PATCH 1/5] arm: dts: omap3-gta04: Add missing nodes to fully
describe gta04 board
Hi Marek,
You seem to add some DT nodes for hw that doesn't have drivers in
mainline. I think you should leave those out until the driver itself
is upstream and the bindings for it is documented.

The omap-pwm driver is not yet upstream and thus the bindings are not final.

I don't think any of the above devices have documented bindings so I
don't think it is a good idea to add the nodes now.

Any reason why you don't use OMAP_IOPAD macro for the I2C pins?
