GPIO bulk updates for the v4.5 kernel cycle: Infrastructural changes: - In struct gpio_chip, rename the .dev node to .parent to better reflect the fact that this is not the GPIO struct device abstraction. We will add that soon so this would be totallt confusing. - It was noted that the driver .get_value() callbacks was sometimes reporting negative -ERR values to the gpiolib core, expecting them to be propagated to consumer gpiod_get_value() and gpio_get_value() calls. This was not happening, so as there was a mess of drivers returning negative errors and some returning "anything else than zero" to indicate that a line was active. As some would have bit 31 set to indicate "line active" it clashed with negative error codes. This is fixed by the largeish series clamping values in all drivers with !!value to [0,1] and then augmenting the code to propagate error codes to consumers. (Includes some ACKed patches in other subsystems.) - Add a void *data pointer to struct gpio_chip. The container_of() design pattern is indeed very nice, but we want to reform the struct gpio_chip to be a non-volative, stateless business, and keep states internal to the gpiolib to be able to hold on to the state when adding a proper userspace ABI (character device) further down the road. To achieve this, drivers need a handle at the internal state that is not dependent on their struct gpio_chip() so we add gpiochip_add_data() and gpiochip_get_data() following the pattern of many other subsystems. All the "use gpiochip data pointer" patches transforms drivers to this scheme. - The Generic GPIO chip header has been merged into the general <linux/gpio/driver.h> header, and the custom header for that removed. Instead of having a separate mm_gpio_chip struct for these generic drivers, merge that into struct gpio_chip, simplifying the code and removing the need for separate and confusing includes. Misc improvements: - Stabilize the way GPIOs are looked up from the ACPI legacy specification. - Incremental driver features for PXA, PCA953X, Lantiq (patches from the OpenWRT community), RCAR, Zynq, PL061, 104-idi-48 New drivers: - Add a GPIO chip to the ALSA SoC AC97 driver. - Add a new Broadcom NSP SoC driver (this lands in the pinctrl dir, but the branch is merged here too to account for infrastructural changes). - The sx150x driver now supports the sx1502.
