Add support for the new smp_twd runtime registration interface to the imx6q platforms, and remove the old compile-time support. The imx6q DTS file is updated to match the TWD DT documentation. Also present in this patch a DTS fix to the timer interrupt routing (the PPI connection uses bits [15:8]) and trigger (rising edge). Cc: Shawn Guo <redacted> Signed-off-by: Marc Zyngier <redacted>
Acked-by: Shawn Guo <redacted> (Tested on imx6q) Regards, Shawn
