Subject: [PATCH v1 5/6] arm64: dts: rockchip: enable sdr-104 on sdmmc
Date: Wed, 11 May 2022 11:01:16 -0400 [thread overview]
Message-ID: <20220511150117.113070-6-pgwipeout@gmail.com> (raw)
In-Reply-To: <20220511150117.113070-1-pgwipeout@gmail.com>
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
