2013-09-27pinctrl: palmas: remove non-require functionLaxman Dewangan1-17/+0
Palmas pinmux and pin configuration support the single pin level configuration in place of pin group. Hence it is only require to pin_config_{set|get} and do not require pin_config_group_{set|get}. As core framework already check for require APIs availability, it is not require to implement as dummy for non-require ops and so removing it.

Replace at91_mux_get_deglitch with at91_mux_pio3_get_deglitch when using sam9x5 (pio3) IP. at91_mux_get_deglitch only test the activation of the "Input Filter" which may be overloaded by the activation of the "Input Filter Slow Clock" to use the input filter as a debounce filter instead of a deglitch filter. Fix at91_mux_pio3_get_debounce to test the activation of the Input Filter before testing the activation of the debounce filter (Input Filter Slow Clock depends on Input Filter).

2013-09-27sh-pfc: r8a7790: add pin definitions for the I2C3 interfaceGuennadi Liakhovetski1-0/+28
There are four I2C interfaces on r8a7790, each of them can be connected to one of the two respective I2C controllers, e.g. interface #0 can be configured to work with I2C0 or with IIC0. Additionally some of those interfaces can also use one of several pin sets. Interface #3 is special, because it can be used in automatic mode for DVFS. It only has one set of pins available and those pins cannot be used for anything else, they also lack the GPIO function. This patch uses the sh-pfc ability to configure pins, not associated with GPIOs and adds support for I2C3 to the r8a7790 PFC set up.

2013-09-19pinctrl: ADI PIN control driver for the GPIO controller on bf54x and bf60x.Sonic Zhang6-0/+2392
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.

2013-08-28pinctrl: Pass all configs to driver on pin_config_set()Sherman Yin23-724/+948
When setting pin configuration in the pinctrl framework, pin_config_set() or pin_config_group_set() is called in a loop to set one configuration at a time for the specified pin or group. This patch 1) removes the loop and 2) changes the API to pass the whole pin config array to the driver. It is now up to the driver to loop through the configs. This allows the driver to potentially combine configs and reduce the number of writes to pin config registers. All c files changed have been build-tested to verify the change compiles and that the corresponding .o is successfully generated.

This one is missed in commit 42fed7ba "pinctrl: move subsystem mutex to pinctrl_dev struct". I think this fixes the race between pin_free() and pin_request() calls. It protects accessing the members of pctldev->desc.

Calling pinctrl_register() means that the driver is fully initialized and might accept pinmux/pinconf requests, so pin groups must be parsed before. This patch fixes this problem by moving device tree parsing before call to pinctrl_register(). In addition, this fixes support for hogs on pin controllers handled by pinctrl-samsung driver.

The symbol SPEAr310_pinctrl_of_match does not exist at all. Fix it. We didn't hit the compile error because this driver can only be built-in now. Signed-off-by: Axel Lin <axel.lin@ingics.com> Acked-by: Viresh Kumar <viresh.kumar@linaro.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2013-08-23pinctrl: sunxi: Add Allwinner A20 pins setMaxime Ripard2-0/+1019
The Allwinner A20 is pin-compatible with the older A10, so the two pin set are quite similar. However, since the A20 has new features, we can't just use the A10 pin set as is, and we need to define our own for the A20.

The Allwinner A31 SoC uses the same IP than the one found in the A10/A13, with only different pins. Add the pins and the associated functions found in the A31.

2013-08-23pinctrl: core: Remove unnecessary test for desc->nameAxel Lin1-3/+1
The implementation in pinctrl_register_one_pin() ensures pindesc->name is always not NULL before insert the pindesc to radix tree. If the desc return from pin_desc_get is not NULL, desc->name is always not NULL. Signed-off-by: Axel Lin <axel.lin@ingics.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
