Sorry for the noise here:), but I find there is some mmc stuff which confuse me. Maybe Randy could elaborate more? Your sdmmc claims to support UHS-I mode like sd-uhs-sdr104, etc, which will ask dw_mmc to switch vqmmc from 3V3 to 1V8 after sending CMD11. But the vqmmc is vccio_sd which is fixed as 3V3? :) > > > Heiko > > [0] https://git.kernel.org/cgit/linux/kernel/git/mmind/linux-rockchip.git/commit/?id=e00fdd4931ea4c47f53cba59b7a3800677546bea > > > _______________________________________________ > Linux-rockchip mailing list > Linux-rockchip@lists.infradead.org > http://lists.infradead.org/mailman/listinfo/linux-rockchip >

The act8846-based boards seem to have some issue when trying to do the switch to 1.8V, resulting in mmc errors and the mmc-core switching back to 3.3V. I think this might be caused by a bug in the act8846 driver or some dts mistake. But so far nobody had the time and enthusiasm to investigate :-) Heiko -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

I double check the regulators settings in dts after the sdcard issue, I found I didn't make them match the hardware of firefly reload board.

And the sdmmc0_vdd that vccio_sd is connected to is exactly that ... according to the rk3288 datasheet the "SDMMC0 Digital IO Power Supply", so that connection is not only meaningful for the iodomains, but _is_ an actual supply and if you turn off vccio_sd, you probably won't get any sdmmc transfers at all ;-) . So yes, due to the resistor misheap vccio_sd should stay limited to 3.3V, but its connection as vqmmc should stay. -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
