+From 2028a24d161da25b827b394bdcec4deba5d2efd9 Mon Sep 17 00:00:00 2001

+Subject: [PATCH 36/53] soc: mediatek: PMIC wrap: SPI_WRITE needs a different
+ bitmask for MT2701/7623
+
+Different SoCs will use different bitmask for the SPI_WRITE command. This
+patch defines the bitmask in the pmic_wrapper_type struct. This allows us
+to support new SoCs with a different bitmask to the one currently used.
