This driver is based on linux/arch/mips/bcm63xx/gpio.c, simplified to allow
defining one or two independent banks for each Broadcom SoC.

Add the imx_rgpio2p driver for Rapid GPIO2P controllers on i.MX7ULP.
Have added all ports on RGPIO2P_0 and RGPIO2P_1.
The configurations CONFIG_IMX_RGPIO2P and CONFIG_DM_GPIO must be set
to y to enable the drivers.
To use the GPIO function, the IBE and OBE needs to set in IOMUXC.
We did not set the bits in driver, but leave them to IOMUXC settings
of the GPIO pins. User should use IMX_GPIO_NR to generate the GPIO number
for gpio APIs access.

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.

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.

Tegra186's GPIO controller register layout is significantly different from
previous chips, so add a new driver for it. In fact, there are two
different GPIO controllers in Tegra186 that share a similar register
layout, but very different port mapping. This driver covers both.
The DT binding is already present in the Linux kernel (in linux-next via
the Tegra tree so far).

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

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

Move the axp-gpio code out of the drivers/power/axp*.c code, and into
a new separate axpi-gpio driver.
This change drops supports for the gpio3 pin on the axp209, as that requires
special handling, and no boards are using it.
Besides cleaning things up by moving the code to a separate driver, as
a bonus this change also adds support for the (non vusb) gpio pins on the
axp221 and the gpio pins on the axp152.
The new axp-gpio driver gets its own Kconfig option, and is only enabled
on boards which need it. Besides that it only gets enabled in the regular
u-boot build and not for the SPL as we never need it in the SPL.

Add driver model support for GPIOs. Since existing GPIO drivers do not use
driver model, this feature must be enabled by CONFIG_DM_GPIO. After all
GPO drivers are converted over we can perhaps remove this config.
Tests are provided for the sandbox implementation, and are a sufficient
sanity check for basic operation.
The GPIO uclass understands the concept of named banks of GPIOs, with each
GPIO device providing a single bank. Within each bank the GPIOs are numbered
using an offset from 0 to n-1. For example a bank named 'b' with 20
offsets will provide GPIOs named b0 to b19.
Anonymous GPIO banks are also supported, and are just numbered without any
prefix.
Each time a GPIO driver is added to the uclass, the GPIOs are renumbered
accordinging, so there is always a global GPIO numbering order.

The gpio spec for bf54x and bf60x differ a lot from the old gpio driver for bf5xx.
A lot of machine macros are used to accomodate both code in one gpio driver.
This patch split the old gpio driver and move new gpio2 support to the generic
gpio driver folder.
- To enable gpio2 driver, macro CONFIG_ADI_GPIO2 should be defined in the board's
config header file.
- The gpio2 driver supports bf54x, bf60x and future ADI processors, while the
older gpio driver supports bf50x, bf51x, bf52x, bf53x and bf561.
- All blackfin specific gpio function names are replaced by the generic gpio APIs.

Microblaze uses gpio which is connected to the system reset.
Currently gpio subsystem wasn't used for it.
Add gpio driver and change Microblaze reset logic to be done
via gpio subsystem.
There are various configurations which Microblaze can have
that's why gpio_alloc/gpio_alloc_dual(for dual channel)
function has been introduced and gpio can be allocated
dynamically.
Adding several gpios IP is also possible and supported.
For listing gpio configuration please use "gpio status" command
This patch also remove one compilation warning:
microblaze-generic.c: In function 'do_reset':
microblaze-generic.c:38:47: warning: operation on '*1073741824u'
