It turns out that sunxi_mmc_oclk_onoff has way too short timeout ofr setting the clock. So here are some patches for - bumping the timout - spamming dmesg when the time to set the clock seems too long - setting SDXC_LOW_POWER_ON which is unset but never set Also feel free to just bump the timeout to reasonably high value so the board can boot reliably with mmc clock gating enabled. Thanks Michal Michal Suchanek (2): mmc: sunxi: fix timeout in sunxi_mmc_oclk_onoff mmc: sunxi: Also set SDXC_LOW_POWER_ON drivers/mmc/host/sunxi-mmc.c | 24 +++++++++++++++++++++--- 1 file changed, 21 insertions(+), 3 deletions(-) -- 2.1.4
