mfd: madera: Add Madera core support for CS47L92

2019-07-02T11:11:31+00:00

This patch adds all the core support and defines for the Cirrus
Logic CS42L92, CS47L92 and CS47L93 smart audio CODECs.

Registers or fields are named MADERA_* if it is part of the
common hardware platform and does not conflict with any other
Madera codecs. It is named CS47L15_* if it is unique to CS47L15
and conflicts with definitions on other codecs.

mfd: Add ST Multi-Function eXpander (STMFX) core driver

2019-05-10T07:21:23+00:00

STMicroelectronics Multi-Function eXpander (STMFX) is a slave controller
using I2C for communication with the main MCU. Main features are:
- 16 fast GPIOs individually configurable in input/output
- 8 alternate GPIOs individually configurable in input/output when other
STMFX functions are not used
- Main MCU IDD measurement
- Resistive touchscreen controller

mfd: altera-sysmgr: Add SOCFPGA System Manager

2019-04-02T06:37:45+00:00

The SOCFPGA System Manager register block aggregates different
peripheral functions into one area.
On 32 bit ARM parts, handle in the same way as syscon.
On 64 bit ARM parts, the System Manager can only be accessed by
EL3 secure mode. Since a SMC call to EL3 is required, this new
driver uses regmaps similar to syscon to handle the SMC call.

Since regmaps abstract out the underlying register access, the
changes to drivers accessing the System Manager are minimal.

The QMX86 is a PLD present on some TQ-Systems ComExpress modules. It
provides 1 or 2 I2C bus masters, 8 GPIOs and a watchdog timer. Add an
MFD which will instantiate the individual drivers.

mfd: lochnagar: Add support for the Cirrus Logic Lochnagar

2019-02-07T10:44:00+00:00

Lochnagar is an evaluation and development board for Cirrus
Logic Smart CODEC and Amp devices. It allows the connection of
most Cirrus Logic devices on mini-cards, as well as allowing
connection of various application processor systems to provide a
full evaluation platform. This driver supports the board
controller chip on the Lochnagar board. Audio system topology,
clocking and power can all be controlled through the Lochnagar
controller chip, allowing the device under test to be used in
a variety of possible use cases.

As the Lochnagar is a fairly complex device this MFD driver
allows the drivers for the various features to be bound
in. Initially clocking, regulator and pinctrl will be added as
these are necessary to configure the system. But in time at least
audio and voltage/current monitoring will also be added.
