+Subject: clk: pistachio: Fix wrong SDHost card speed
+
+The SDHost currently clocks the card 4x slower than it
+should do, because there is fixed divide by 4 in the
+sdhost wrapper that is not present in the clock tree.
+To model this add a fixed divide by 4 clock node in
+the SDHost clock path.
+
+This will ensure the right clock frequency is selected when
+the mmc driver tries to configure frequency on card insert.
