To get GPU working with the OCMEM, the oxili_ocmemgx_clk clock should be
enabled. Pass it to the GPU to get it to work on apq8074/msm8974 boards.

Uhh.. this clock should be managed by RPM with:

type = MEM
id = 2

just like it's defined for 8994 today.

Could you try adding it in rpmcc and confirming?

There is an RPM_SMD_OCMEMGX_CLK clk already, it is a bus clock for the ocmemnoc.
It's wrong.

Can you possibly be more specific here?

On 8974 RPM_SMD_OCMEMGX_CLK is a core clock for ocmem and a bus clock for ocmemnoc.

On 8994 this clocks is just a core clock for ocmem, there is no ocmemnoc.
