Subject: [PATCH 100/478] arm64: dts: rockchip: enable sdr-104 on sdmmc
|
|
|
|
Now that we have working io-domain support, we can enable higher date
|
|
rates on the sdmmc card.
|
|
|
|
Before:
|
|
Timing buffered disk reads: 68 MB in 3.08 seconds = 22.07 MB/sec
|
|
|
|
After:
|
|
Timing buffered disk reads: 188 MB in 3.02 seconds = 62.29 MB/sec
