Introduce driver to support "fairchild,74hc595" devices.
1. Take linux drivers/drivers/gpio/gpio-74x164.c as reference.
2. Following the naming used in Linux driver with gen_7x164 as the prefix.
3. Enable CONFIG_DM_74X164 to use this driver.
4. Follow Documentation/devicetree/bindings/gpio/gpio-74x164.txt to add device
nodes
5. Tested on i.MX6 UltraLite with 74LV595 using gpio command and oscillograph.

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 [ ]
=> dm tree:
i2c [ ] | | `-- i2c@021a8000
gpio [ ] | | |-- gpio@30
gpio [ ] | | `-- gpio@32

This patch adds a DM GPIO driver for the Marvell MVEBU SoCs. There are
other non-DM drivers that might be used on these platforms. But this
patch creates a new DM driver. Which will be used by all Armada XP/38x
boards. Other MVEBU SoC (Kirkwood / Orion) may follow once they
support DM as well.

In PIC32 GPIO controller is part of PIC32 pin controller.
PIC32 has ten independently programmable ports and each with multiple pins.
Each of these pins can be configured and used as GPIO, provided they
are not in use for other peripherals.
