Hi,
The patch sets add support for MediaTek PMIC MT6397 MFD core and its regulator
driver.
This is hardware layout for access PMIC MT6397 from AP SoC MT8135.
Between PMIC MT6397 and MT8135, the physical signal channel is SPI bus.
A specific hardware called PMIC Wrapper or PWRAP to handle access protocols in
both PMIC and AP side.

Changes since v2
================
(1) Patch 1/8: Update kernel config of MT8135 PMIC Wrapper. It needs to select
REGMAP.
(2) Patch 2/8: Update patch of MT6397 MFD driver to fix defeat of coding styles.
(3) Patch 3/8: Update MT6397 regulator driver
- use standard helpers for ops ".set_voltage_sel", ".get_voltage_sel"
and ".is_enabled"
- remove regulator's DT matching codes in the driver.
- fix defeat of coding styles.
(4) Patch 4/8: Update document for MT8135 PMIC wrapper.
(5) Patch 5/8: Update document for MT6397 MFD.
(6) Patch 6/8: Update document for MT6397 regulators.
(7) Patch 7/8: Update device tree for MT8135 PMIC wrapper in mt8135.dtsi.
(8) Patch 8/8: Add device tree for MT6397 MFD and regulators in
mt8135-evbp1.dts board file.
Second version (v2):

Changes since v1
================
(1) Patch 1/8: Add MT8135 PMIC wrapper driver for SoC's proprietary hardware.
(2) Patch 2/8: Update patch of MT6397 MFD driver to contain only MFD related
codes and fix defeat of coding styles.
(3) Patch 3/8: Update MT6397 regulator driver
- use helpers and standard ways for specifying data in regulator
description.
- add more comments to explaining why the driver implement its own
regulator_ops for ".is_enabled", ".set_voltage_sel" and ".get_voltage_sel".
- update driver implement for coding styles.
(4) Patch 4/8: Add document for MT8135 PMIC wrapper.
(5) Patch 5/8: Update document for MT6397 MFD.
(6) Patch 6/8: Update document for MT6397 regulators.
(7) Patch 7/8: Add device tree for MT6397 MFD in mt8135.dtsi.
(8) Patch 8/8: Update device tree for MT6397 regulators in mt8135.dtsi.
Initial version (v1):
http://lists.infradead.org/pipermail/linux-arm-kernel/2014-November/302984.html
This driver is based on 3.18-rc1.
