Subject: [PATCH 00/18] mmc: meson-gx: code and performance improvements
Date: Tue, 14 Feb 2017 21:05:16 +0100 [thread overview]
Message-ID: <74c3a06c-d972-1e70-fb22-744df8ef31d9@gmail.com> (raw)
This patch series includes several improvements and boosted the
read performance from 13 MB/s to 32 MB/s (at 60MHz clock rate)
on a Odroid C2 with a 128GB eMMC module.
Higher frequencies needed tuning in my case. With some hacked
test tuning I reached 52 MB/s at 200MHz.
With a 8GB card 200MHz were stable out of the box, but with
less performacne.
