Sonic Zhang e9a03add0c pinctrl: ADI PIN control driver for the GPIO controller on bf54x and bf60x.
The new ADI GPIO2 controller was introduced since the BF548 and BF60x
processors. It differs a lot from the old one on BF5xx processors. So,
create a pinctrl driver under the pinctrl framework.

- Define gpio ports and pin interrupt controllers as individual platform
  devices.
- Register a pinctrl driver for the whole GPIO ports and pin interrupt
  devices.
- Probe pint devices before port devices. Put device instances into
  the global gpio and pint lists.
- Define peripheral, irq and gpio reservation bit masks for each gpio
  port as runtime resources.
- Save and restore gpio port and pint status MMRs in syscore PM functions.
- Create the plug-in subdrivers to hold the pinctrl soc data for bf54x
  and bf60x. Add soc data into struct adi_pinctrl. Initialize the soc data
  in pin controller probe function. Get the pin groups and functions via
  the soc data reference.
- Call gpiochip_add_pin_range() in gpio device probe function to register
  range cross reference between gpio device and pin control device.
- Get range by pinctrl_find_gpio_range_from_pin(), find gpio_port object
  by container_of() and find adi_pinctrl by pin control device name.
- Handle peripheral and gpio requests in pinctrl operation functions.
- Demux gpio IRQs via the irq_domain created by each GPIO port.

v2-changes:
- Remove unlinke() directive.

v3-changes:
- Rename struct adi_pmx to adi_pinctrl.
- Fix the comments of struct gpio_pint.
- Remove unused pin_base in struct gpio_port.
- Change pint_assign into bool type.
- Add comments about the relationship between pint device and port device
to the driver header.
- Use BIT macro to shift bit.
- Remove all bitmap reservation help functions. Inline reservation functions
into the actual code.
- Remove gpio and offset mutual reference help functions.
- Remove all help functions to find gpio_port and adi_pinctrl structs. Get
range by pinctrl_find_gpio_range_from_pin(), find gpio_port object by
container_of() and find adi_pinctrl by pin control device name.
- Pass bool type usage variable to port_setup help function.
- Separate long bit operations into several lines and add comments.
- Use debugfs to output all GPIO request information.
- Avoid to set drvdata to NULL
- Add explanation to function adi_gpio_init_int()
- Call gpiochip_add_pin_range() in gpio device probe function to register
range cross reference between gpio device and pin control device.
- Remove the reference to pin control device from the gpio_port struct.
Remove the reference list to gpio device from the adi_pinctrl struct.
Replace the global adi_pinctrl list with adi_gpio_port_list. Walk through
the gpio list to do power suspend and resume operations.
- Remove the global GPIO base from struct adi_pinctrl, define pin base in
the platform data for each GPIO port device.
- Initialize adi_pinctrl_setup in arch_initcall().
- print the status of triggers, whether it is in GPIO mode, if it is
flagged to be used as IRQ, etc in adi_pin_dbg_show().
- Create the plug-in subdrivers to hold the pinctrl soc data for bf54x
and bf60x. Add soc data into struct adi_pinctrl. Initialize the soc data
in pin controller probe function. Get the pin groups and functions via
the soc data reference.

v4-changes:
- remove useless system_state checking.
- replace dev_err with dev_warn in both irq and gpio pin cases.
- comment on relationship between irq type and invert operation.
- It is not necessary to check the reservation mode of the requested
pin in IRQ chip operation. Remove the reservation map.
- Use existing gpio/pinctrl subsystem debugfs files. Remove pinctrl-adi2
driver specific debugfs output.
- Add linkport group and function information for bf60x.
- Separate uart and ctsrts pins into 2 groups.
- Separate APAPI and alternative ATAPI pins into 2 groups.
