Hi Nikolaus,

<hns@xxxxxxxxxxxxx> a écrit :
Add SGX GPU node with interrupt. Tested on PandaBoard ES.
Since omap4420/30/60 and omap4470 come with different SGX variants
we need to introduce a new omap4470.dtsi. If an omap4470 board
does not want to use SGX it is no problem to still include
omap4460.dtsi.

Does this even compile?
The node's handle is named sgx_module, not sgx.
