2016-04-08gpiolib: Defer gpio device setup until after gpiolib initializationGuenter Roeck
Since commit ff2b13592299 ("gpio: make the gpiochip a real device"), attempts to add a gpio chip prior to gpiolib initialization cause the system to crash. This happens because gpio_bus_type has not been registered yet. Defer creating gpio devices until after gpiolib has been initialized to fix the problem.

2016-04-08gpio: pxa: fix legacy non pinctrl aware buildsRobert Jarzmik
In legacy pxa builds, ie. non device-tree and platform-data only builds, pinctrl is not yet available. As a consequence, the pinctrl gpio direction change function is a stub, returning always success. In the current state, the gpio driver direction function believes the pinctrl direction change was successful, and exits without actually changing the gpio direction. This patch changes the logic : - if the pinctrl direction function fails, gpio direction will report that failure - if the pinctrl direction function succeeds, gpio direction is changed by the gpio driver anyway. This is sub optimal in the pinctrl aware case, as the gpio direction will be changed twice: once by pinctrl function and another time by the gpio direction function. Yet it should be acceptable in this form, as this is functional for all pxa platforms (device-tree and platform-data), and moreover changing a gpio direction is very very seldom, usually in machine initialization, seldom in drivers probe, and an exception for ac97 reset bug.

2016-04-08gpio / ACPI: ignore GpioInt() GPIOs when requesting GPIO_OUT_*Dmitry Torokhov
When firmware does not use _DSD properties that allow properly name GPIO resources, the kernel falls back on parsing _CRS resources, and will return entries described as GpioInt() as general purpose GPIOs even though they are meant to be used simply as interrupt sources for the device: Device (ETSA) { Name (_HID, "ELAN0001") ... Method(_CRS, 0x0, NotSerialized) { Name(BUF0,ResourceTemplate () { I2CSerialBus( 0x10, /* SlaveAddress */ ControllerInitiated, /* SlaveMode */ 400000, /* ConnectionSpeed */ AddressingMode7Bit, /* AddressingMode */ "\\_SB.I2C1", /* ResourceSource */ ) GpioInt (Edge, ActiveLow, ExclusiveAndWake, PullNone,, "\\_SB.GPSW") { BOARD_TOUCH_GPIO_INDEX } } ) Return (BUF0) } ... } This gives troubles with drivers such as Elan Touchscreen driver (elants_i2c) that uses devm_gpiod_get to look up "reset" GPIO line and decide whether the driver is responsible for powering up and resetting the device, or firmware is. In the above case the lookup succeeds, we map GPIO as output and later fail to request client->irq interrupt that is mapped to the same GPIO. Let's ignore resources described as GpioInt() while parsing _CRS when requesting output GPIOs (but allow them when requesting GPIOD_ASIS or GPIOD_IN as some drivers, such as i2c-hid, do request GPIO as input and then map it to interrupt with gpiod_to_irq).

2016-04-05gpio: tc3589x: implement open drain/source callbackLinus Walleij
This makes use of the new .set_single_ended() callback to set the GPIO line as open drain/open source using hardware. The TC3589x can do this by either disabling the N-MOS transistor (open drain) or the P-MOS transistor (open source) of the output driver stage, in the first case making the signal drive actively low and high impedance as "high" and in the second case actively high and high impedance, which is as close to native open drain support as we come.

2016-04-05gpio: support native single-ended hardware driversLinus Walleij
Some GPIO controllers has a special hardware bit we can flip to support open drain / source. This means that on these hardwares we do not need to emulate OD/OS by setting the line to input instead of actively driving it high/low. Add an optional vtable callback to the driver set_single_ended() so that driver can implement this in hardware if they have it. We may need a pinctrl_gpio_set_config() call at some point to propagate this down to a backing pin control device on systems with split GPIO/pin control.

I am also not sure about not configuring the Simple I/O registers as the hardware I have only uses GPIO block 8.

The mcp23s18 is configurable on clearing the interrupt on either reading INTCAP or GPIO. Since driver reads INTCAP in IRQ and not the GPIO reg need to set control byte for this mode. Signed-off-by: Phil Reid <preid@electromag.com.au> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

2016-03-16gpio: pca953x: Fix pca953x_gpio_set_multiple() on 64-bitGeert Uytterhoeven
pca953x_gpio_set_multiple() divides by 4 to convert from longs to bytes, which assumes a 32-bit platform, and is not correct on 64-bit platforms. Use "sizeof(...)" instead to fix this.
