+Subject: spi: cadence: revert "Add SPI transfer delays"
+
+From: Nam Cao <namcao@linutronix.de>
+
+commit 7a733e060bd20edb63b1f27f0b29cf9b184e0e8b upstream.
+
+The commit 855a40cd8ccc ("spi: cadence: Add SPI transfer delays") adds a
+delay after each transfer into the driver's transfer_one(). However,
+the delay is already done in SPI core. So this commit unnecessarily
+doubles the delay amount. Revert this commit.
