Hi!
The ARTPEC-8 SoC has a DWMMC controller that is compatible with the
Exynos 7 version v2.70a. The main differences from Exynos 7 is that it
does not support HS400 and has an extended data read timeout. To run
this controller we need to add compatibility for ARTPEC-8, because we
need a quirk to separate the configuration of the TMOUT register from
the non ARTPEC-8 versions.
This patchset is dependent on 2 changes that has been added to the mmc
git next branch, but has not yet been merged to mainline:
Patch 2 of this patchset depends on commit 0e6f2c4c2072b ("mmc: dw_mmc:
add common capabilities to replace caps").
Patch 3 of this patchset depends on commit d5bc33487eab3 ("mmc: dw_mmc:
Allow lower TMOUT value than maximum").
Kind regards
Mårten Lindahl
Changes in v2:
- Change compatible string vendor prefix
- Removed unnecessary comment
- Change 1<<0 to BIT(0)
