From: Jonathan Hunter <jonathanh@xxxxxxxxxx> Enabling CQE support on Tegra186 Jetson TX2 has introduced a regression that is causing accesses to the file-system on the eMMC to fail. Errors such as the following have been observed ... mmc2: running CQE recovery mmc2: mmc_select_hs400 failed, error -110 print_req_error: I/O error, dev mmcblk2, sector 8 flags 80700 mmc2: cqhci: CQE failed to exit halt state For now disable CQE support for Tegra186 until this issue is resolved. Fixes: dfd3cb6feb73 arm64: tegra: Add CQE Support for SDMMC4 Signed-off-by: Jonathan Hunter <jonathanh@xxxxxxxxxx> Signed-off-by: Thierry Reding <treding@xxxxxxxxxx> --- Hi ARM SoC maintainers, Turned out there was a hardware bug that currently prevents CQE from working on Tegra186. Patches for this are being worked on and are on track to be merged for v5.2 but they are too involved to make it into v5.1, so let's back out CQE support on Tegra186. Can you please apply this for v5.1-rc3?
