[PATCH v2] mmc: sdhci-of-dwcmshc: add ACPI match data for BlueField-3 SoC
Posted by Liming Sun 3 years, 8 months ago 
Commit 08f3dff799d43 introduces the of_device_get_match_data()
checking for some chip but breaks the BlueField-3 firmware which
uses ACPI instead. This commit adds the ACPI match data and
quirks/quirks2 to re-enable the support of BlueField-3 SoC.

Please re-base this patch because it does not apply to
latest mmc "next" branch.
