DEVCONTROL0,1 needs to be modelled in DT-only boot as well. OMAP243X SDP # md.l 0x490022e8 1 490022e8: 002fff80 ../. OMAP243X SDP # md.l 0x49002274 1 49002274: 04000000 ....

OMAP243X SDP # boot happily detects the mmc partitions. http://slexy.org/view/s21QaCLMWQ we modelled pbias in dt so far - this is necessary, but two other steps are needed as well (based on arch/arm/mach-omap2/hsmmc.c used in non-dt boot): a) OMAP243X_CONTROL_DEVCONF1:: OMAP243X_MMC1_ACTIVE_OVERWRITE should be tweaked based on vdd b) OMAP2_CONTROL_DEVCONF0::OMAP2_MMCSDIO1ADPCLKISEL should be set for internal_clk (sdp2430). -- Regards, Nishanth Menon -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
