From 506b811d75ec94b10eda673f8677ef507f870077 Mon Sep 17 00:00:00 2001
From: John Crispin <blogic@openwrt.org>
Date: Wed, 20 Jan 2016 10:21:42 +0100
Subject: [PATCH 36/91] 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.
