ARM: dts: rockchip: Make rk3288-veyron-mickey's emmc work again
When I try to boot rk3288-veyron-mickey I totally fail to make the eMMC work. Specifically my logs (on Chrome OS 4.19): mmc_host mmc1: card is non-removable. mmc_host mmc1: Bus speed (slot 0) = 400000Hz (slot req 400000Hz, actual 400000HZ div = 0) mmc_host mmc1: Bus speed (slot 0) = 50000000Hz (slot req 52000000Hz, actual 50000000HZ div = 0) mmc1: switch to bus width 8 failed mmc1: switch to bus width 4 failed mmc1: new high speed MMC card at address 0001 mmcblk1: mmc1:0001 HAG2e 14.7 GiB mmcblk1boot0: mmc1:0001 HAG2e partition 1 4.00 MiB mmcblk1boot1: mmc1:0001 HAG2e partition 2 4.00 MiB mmcblk1rpmb: mmc1:0001 HAG2e partition 3 4.00 MiB, chardev (243:0) mmc_host mmc1: Bus speed (slot 0) = 400000Hz (slot req 400000Hz, actual 400000HZ div = 0) mmc_host mmc1: Bus speed (slot 0) = 50000000Hz (slot req 52000000Hz, actual 50000000HZ div = 0) mmc1: switch to bus width 8 failed mmc1: switch to bus width 4 failed mmc1: tried to HW reset card, got error -110 mmcblk1: error -110 requesting status mmcblk1: recovery failed! print_req_error: I/O error, dev mmcblk1, sector 0 ... When I remove the '/delete-property/mmc-hs200-1_8v' then everything is hunky dory. That line comes from the original submission of the mickey dts upstream, so presumably at the time the HS200 was failing and just enumerating things as a high speed device was fine. ...or maybe it's just that some mickey devices work when enumerating at "high speed", just not mine? In any case, hs200 seems good now. Let's turn it on. Signed-off-by: Douglas Anderson <dianders@chromium.org> Signed-off-by: Heiko Stuebner <heiko@sntech.de>
