The device trees look good: Reviewed-by: Joel Stanley <joel@xxxxxxxxx> I've applied patches 1-3 to the aspeed tree for v5.14. I made a little fix to patch 3 as it needed to add the new device tree to the makefile. When I was testing on my A2 EVB I saw this: [ 1.436219] sdhci-aspeed 1e750100.sdhci: Requested out of range phase tap 192 for 9 degrees of phase compensation at 1562500Hz, clamping to tap 15 [ 1.450913] sdhci-aspeed 1e750100.sdhci: Requested out of range phase tap 963 for 45 degrees of phase compensation at 1562500Hz, clamping to tap 15 Do you know what is happening there? Cheers, Joel
