From 2028a24d161da25b827b394bdcec4deba5d2efd9 Mon Sep 17 00:00:00 2001 From: John Crispin Date: Wed, 20 Jan 2016 10:21:42 +0100 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.
