i.MX6Q/DL Lowering power consumption in suspend mode

There should be a quick and easy optimisation when screen suspension occurs. The IPU suspension control should eventually reach the function:


void mx6q_ipuv3_pg(int enable) { /*TODO*/ }


However it hasn't been implemented and there seems to be a large chunk of the BSP missing; although there are examples for i.MX53 and i.MX51 the part for i.MX6 is missing.


See Android BSP imx-android-13.4.1



There does seem to be a small amount of documentation in the Reference Manual (page 1348), but none of the PG memory map exists in the source code BSP. This part is weakly supported. Is ther any help the community can give on this problem?


Although the documentation on i.MX 6Dual/6Quad Power Consumption Management (rev0) suggests that "Futher optimisations are planned to be implemented in future BSP releases...". Surely I am not the only person who needs low power consumption when in suspend mode?
