be8313feee mips: mscc_sgpio: Add the MSCC serial GPIO device (SIO)
This add support for the the MSCC serial GPIO driver in MSCC
VCoreIII-based SOCs.

By using a serial interface, the SIO controller significantly extends
the number of available GPIOs with a minimum number of additional pins
on the device. The primary purpose of the SIO controller is to connect
control signals from SFP modules and to act as an LED controller.

This adds the base driver.

02aea4da1d gpio: mscc-bitbang-spi: Add a simple gpio driver for bitbgang spi
The VCore III SoCs such as the Luton but also the Ocelot can remap an SPI
flash directly in memory. However, for writing in the flash the
communication has to be done by software.

Each of the signal used for the SPI are exposed in a single register. In
order to be able to use the soft-spi driver, the management of this pin
is done through this simple gpio driver.

Even if the main purpose of this driver is to be used by soft-spi, it can
still be used as a normal gpio driver but with limitation: for example
the first pin can't be used as output.

4a69366967 microblaze: Convert generic platform to DM gpio
Converting GPIO to DM requires to do changes in reset subsystem
that's why support for Microblaze soft reset via sysreset and GPIO
sysreset support was added.
These two patches enables enabling GPIO DM.
Microblaze soft reset is bind at last reset method.

GPIO reset is handled via sysreset with adding this fragment to DT.

gpio-restart {
	compatible = "gpio-restart";
	gpios = <&reset_gpio 0 0 0>;
	/* 3rd cell ACTIVE_HIGH = 0, ACTIVE_LOW = 1 */
};

hard-reset-gpio property is not documented and also handled.
Conversion is required.

Unfortunately do_reset is required for SPL that's why use only soft
microblaze reset for now.

5746b0df9c gpio: Add driver for TI PCF8575 I2C GPIO expander
TI's PCF8575 is a 16-bit I2C GPIO expander.The device features a
16-bit quasi-bidirectional I/O ports. Each quasi-bidirectional I/O can
be used as an input or output without the use of a data-direction
control signal. The I/Os should be high before being used as inputs.
Read the device documentation for more details[1].

This driver is based on pcf857x driver available in Linux v4.7 kernel.
It supports basic reading and writing of gpio pins.

07d31f8f98 dm: gpio: Add driver for MPC85XX GPIO controller
This patch adds a driver for the built-in GPIO controller of the MPC85XX
SoC (probably supporting other PowerQUICC III SoCs as well).

Each GPIO bank is identified by its own entry in the device tree, i.e.

gpio-controller@fc00 {
      #gpio-cells = <2>;
      compatible = "fsl,pq3-gpio";
      reg = <0xfc00 0x100>
}

By default, each bank is assumed to have 32 GPIOs, but the ngpios
setting is honored, so the number of GPIOs for each bank in configurable
to match the actual GPIO count of the SoC (e.g. the 32/32/23 banks of
the P1022 SoC).

The usual functions of GPIO drivers (setting input/output mode and output
value setting) are supported.

The driver has been tested on MPC85XX, but it is likely that other
PowerQUICC III devices will work as well.

037734393e dm: gpio: pca953x: introduce driver model support for pca953x
Introduce a new driver that supports driver model for pca953x.
The pca953x chips are used as I2C I/O expanders.
This driver is designed to support the following chips:
"
4 bits: pca9536, pca9537
8 bits: max7310, max7315, pca6107, pca9534, pca9538, pca9554,
        pca9556, pca9557, pca9574, tca6408, xra1202
16 bits: max7312, max7313, pca9535, pca9539, pca9555, pca9575,
         tca6416
24 bits: tca6424
40 bits: pca9505, pca9698
"
But for now this driver only supports max 24 bits and pca953x compatible
chips. pca957x compatible chips are not supported now.
These can be addressed when we need to add such support for the different
chips.
This driver has been tested on i.MX6 SoloX Sabreauto board with max7310
i2c expander using gpio command as following:

=>gpio status -a
Bank gpio@30_:
gpio@30_0: input: 1 [ ]
