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.
