Subject[PATCH v1 1/1] mmc: sdhci-of-dwcmshc: add ACPI match data for BlueField-3 SoC
Date
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.
