-If pinctrl configurations for higher speed modes are missing, the
-stack currently uses the no 1.8V quirk. This comes close to what
-we need but not exactly: E.g. if a eMMC chip uses 1.8V signaling
-(by specifying a 1.8V only vqmmc-supply) while not providing any
-100MHz/200MHz pinctrl configurations then the SDHCI_QUIRK2_NO_1_8_V
-leads the stack to print signaling voltage switch failed errors
-continuously:
-  mmc1: Switching to 3.3V signalling voltage failed
-
-Presumably because the stack tries to use 3.3V signaling:
-
-  # cat /sys/kernel/debug/mmc1/ios
-  ...
-  timing spec:    8 (mmc DDR52)
-  signal voltage: 0 (3.30 V)
-  ...
-
-With using SDHCI_QUIRK2_NO_UHS_HS200_HS400 we prevent the stack
-from choosing any modes require speeds higher than 52MHz while
-still allowing to select modes using 1.8V at lower speeds (e.g.
-DDR52):
-
-  # cat /sys/kernel/debug/mmc1/ios
-  ...
-  timing spec:    8 (mmc DDR52)
-  signal voltage: 1 (1.80 V)
-  ...
