use the state value.

The callback is now invoked to set the device PM state in all cases, so
the usage of ctrl_command is redundant.

The device PM subsystem already holds the device state, so there is no
need to keep duplicates inside the device. The pm_device_state_get has
been refactored to just return the device state. Note that this is still
not safe, but the same applied to the previous implementation. This
problem will be addressed later.

The Texas Instruments TCA9538 is an 8 pin GPIO port expander.
It operates on an I2C bus with 2 configurable address pins. The
device has an interrupt output pin that is asserted when any pin
configured as an input changes state.
Added under the PCA953X name to allow other similar parts to
use the same driver.

Create version 2 of the MEC GPIO driver to support MEC172x to not
interfere with MEC152x. When the MEC172x ECIA interrupt aggregator
driver is ready, this driver will use ECIA for registering GPIO
interrupt callbacks instead of maintaining its own interrupt table.
Add V2 DT binding.
Add the Kconfig configuration settings for the MEC172x GPIO
V2 driver at the SoC and board level.
Add port id to DT allowing use of DT FOR EACH macro in the driver.

Move all PM_DEVICE_STATE_* definitions to an enum. The

Most APIs have the default synchronous and an asynchronous version
with the sufix _async because that is the most common use.
All devices in tree right now are using the synchronous version, so

On Apollo Lake, each GPIO controller has more than 32 pins.
But Zephyr API can only manipulate 32 pins per controller.
So the workaround is to divide each hardware GPIO controller
into 32-pin blocks so each block has a GPIO driver instance.
Compounding to the issue is that there cannot be two device
tree nodes with same register address. So another workaround
is to increment the register addresses by 1 for each block.
So when mapping the address, the lowest 8-bit needs to be
masked to get the actual hardware address.

To keep compatibility between the old GPIO API implementation and a new
one introduced in the Zephyr 2.2.0 release the gpio_pin_configure()
function was accepting interrupt flags. In the new API implementation
interrupt flags are only accepted by gpio_pin_interrupt_configure()
function.
This temporary support for INT flags in gpio_pin_configure should have
been removed in the Zephyr 2.4.0 release.
