Stephen, I can reproduce the problem with gcc-4.6.3, but at a
different line number (weird):

/c/wfg/sound/arch/arm/mach-imx/imx31-dt.c:51:2: warning: initialization from incompatible pointer type [enabled by default]
/c/wfg/sound/arch/arm/mach-imx/imx31-dt.c:51:2: warning: (near initialization for '__mach_desc_IMX31_DT.init_time') [enabled by
default]

 45 
 46 DT_MACHINE_START(IMX31_DT, "Freescale i.MX31 (Device Tree Support)")
 47         .map_io         = mx31_map_io,
 48         .init_early     = imx31_init_early,
 49         .init_irq       = mx31_init_irq,
 50         .handle_irq     = imx31_handle_irq,
 51         .init_time      = mx31_clocks_init_dt,
 52         .init_machine   = imx31_dt_init,
 53         .dt_compat      = imx31_dt_board_compat,
 54         .restart        = mxc_restart,
 55 MACHINE_END

Thanks,
