The device trees look good:
Reviewed-by: Joel Stanley <joel@jms.id.au>
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
