Subject: [PATCH 1/3 v3] pinctrl: ADI PIN control driver for the GPIO controller on bf54x and bf60x.
From: Sonic Zhang <sonic.zhang@...log.com>
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.

+According to the BF54x HRM, pint means "pin interrupt".
+http://www.analog.com/static/imported-files/processor_manuals/ADSP-BF54x_hwr_rev1.2.pdf
+
+ADSP-BF54x processor Blackfin processors have four SIC interrupt chan-
+nels dedicated to pin interrupt purposes. These channels are managed by
+four hardware blocks, called PINT0, PINT1, PINT2, and PINT3. Every PINTx
+block can sense to up to 32 pins. While PINT0 and PINT1 can sense the
+pins of port A and port B, PINT2 and PINT3 manage all the pins from port
+C to port J as shown in Figure 9-2.
+
+n BF54x HRM:
+The ten GPIO ports are subdivided into 8-bit half ports, resulting in lower and
+upper half 8-bit units. The PINTx_ASSIGN registers control the 8-bit multi-
+plexers shown in Figure 9-3. Lower half units of eight pins can be
+forwarded to either byte 0 or byte 2 of either associated PINTx block.
+Upper half units can be forwarded to either byte 1 or byte 3 of the pin
+interrupt blocks, without further restrictions.
+
+All MMR registers in the pin interrupt module are 32 bits wide. To simply the
+mapping logic, this driver only maps a 16-bit gpio port to the upper or lower
+16 bits of a PINTx block. You can find the Figure 9-3 on page 583.
+
+Each IRQ domain is binding to a GPIO bank device. 2 GPIO bank devices can map
+to one PINT device. Two in "struct gpio_pint" are used to ease the PINT
+interrupt handler.
+
+The GPIO bank mapping to the lower 16 bits of the PINT device set its IRQ
+domain pointer in domain[0]. The IRQ domain pointer of the other bank is set
+to domain[1]. PINT interrupt handler adi_gpio_handle_pint_irq() finds out
+the current domain pointer according to whether the interrupt request mask
+is in lower 16 bits (domain[0]) or upper 16bits (domain[1]).
+
+A PINT device is not part of a GPIO port device in Blackfin. Multiple GPIO
+port devices can be mapped to the same PINT device.
