| Subject: ARM: dts: rockchip: Make rk3288-veyron-mickey's emmc work again |
| |
| [ Upstream commit 99fa066710f75f18f4d9a5bc5f6a711968a581d5 ] |
| |
| 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. |
