git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio Pull GPIO updates from Linus Walleij: "Here is the bulk of GPIO changes for v4.5. Notably there are big refactorings mostly by myself, aimed at getting the gpio_chip into a shape that makes me believe I can proceed to preserve state for a proper userspace ABI (character device) that has already been proposed once, but resulted in the feedback that I need to go back and restructure stuff. So I've been restructuring stuff. On the way I ran into brokenness (return code from the get_value() callback) and had to fix it. Also, refactored generic GPIO to be simpler. Some of that is still waiting to trickle down from the subsystems all over the kernel that provide random gpio_chips, I've touched every single GPIO driver in the kernel now, oh man I didn't know I was responsible for so much... Apart from that we're churning along as usual. I took some effort to test and retest so it should merge nicely and we shook out a couple of bugs in -next. 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" * tag 'gpio-v4.5-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (220 commits) gpio: generic: make bgpio_pdata always visible gpiolib: fix chip order in gpio list gpio: mpc8xxx: Do not use gpiochip_get_data() in mpc8xxx_gpio_save_regs() gpio: mm-lantiq: Do not use gpiochip_get_data() in ltq_mm_save_regs() gpio: brcmstb: Allow building driver for BMIPS_GENERIC gpio: brcmstb: Set endian flags for big-endian MIPS gpio: moxart: fix build regression gpio: xilinx: Do not use gpiochip_get_data() in xgpio_save_regs() leds: pca9532: use gpiochip data pointer leds: tca6507: use gpiochip data pointer hid: cp2112: use gpiochip data pointer bcma: gpio: use gpiochip data pointer avr32: gpio: use gpiochip data pointer video: fbdev: via: use gpiochip data pointer gpio: pch: Optimize pch_gpio_get() Revert "pinctrl: lantiq: Implement gpio_chip.to_irq" pinctrl: nsp-gpio: use gpiochip data pointer pinctrl: vt8500-wmt: use gpiochip data pointer pinctrl: exynos5440: use gpiochip data pointer pinctrl: at91-pio4: use gpiochip data pointer ...
2016-01-05gpio: generic: factor into gpio_chip structLinus Walleij
The separate struct bgpio_chip has been a pain to handle, both by being confusingly similar in name to struct gpio_chip and for being contained inside a struct so that struct gpio_chip is contained in a struct contained in a struct, making several steps of dereferencing necessary. Make things simpler: include the fields directly into <linux/gpio/driver.h>, #ifdef:ed for CONFIG_GENERIC_GPIO, and get rid of the <linux/basic_mmio_gpio.h> altogether. Prefix some of the member variables with bgpio_* and add proper kerneldoc while we're at it. Modify all users to handle the change and use a struct gpio_chip directly. And while we're at it: replace all container_of() dereferencing by gpiochip_get_data() and registering the gpio_chip with gpiochip_add_data().

2015-12-01ARM: s3c64xx: allow building without board supportArnd Bergmann
Most of the code for the s3c64xx platform is only used when booting with ATAGS based board files, but not when using device-tree. This tries to identify all the s3c64xx specific code that is unneeded when CONFIG_ATAGS is not set, so we can build a smaller DT-only kernel if configured that way. All board support is still left intact but now depends on the CONFIG_ATAGS symbol that users may intentionally disable. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2015-12-01ARM: s3c64xx: multiplatform supportArnd Bergmann
After all preparation work is done, we can finally move the Kconfig option for s3c64xx into ARCH_MULTIPLATFORM. This implies allowing SAMSUNG_ATAGS for multiplatform again, but now disallowing the ADC driver below it, as that still has dependencies on header files. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2015-12-01ARM: s3c64xx: use common debug-ll implementationArnd Bergmann

2015-12-01ARM: s3c64xx: use new adc/touchscreen driverArnd Bergmann
The old ADC and touchscreen drivers are not compatible with multiplatform support, but we can use the exynos-adc driver as a replacement. This changes the common device creation functions for s3c64xx (but not s3c24xx for now) to use the new driver. To do this, we have to pass the interrupt resources in the opposite order and pass the platform data in the adc device node. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2015-12-01ARM: s3c64xx: enable sparse IRQ supportArnd Bergmann
This is another prerequisite for enabling multiplatform support, and it is the part I am least certain about. I assume it will cause the extra boot message "Cannot allocate irq_descs @ IRQ%d, assuming pre-allocated" to be printed, but otherwise work ok.

2015-12-01ARM: s3c64xx: prepare initcalls for multiplatformArnd Bergmann
In a multiplatform kernel, each initcall is run regardless of the platform it is meant for, so it must not attempt to access SoC-specific registers. This adds 'if (soc_is_s3c64xx)' to all initcalls that are specific to the s3c64xx platform, to prevent them from breaking other platforms once we can build them into a combined kernel.

2015-11-21ASoC: samsung: pass filter function as pointerArnd Bergmann
As we are now passing the filter data as pointers to the drivers, we can take the final step and also pass the filter function the same way. I'm keeping this change separate, as there it's less obvious that this is a net win. Upsides of this are: - The ASoC drivers are completely independent from the DMA engine implementation, which simplifies the Kconfig logic and in theory allows the same sound drivers to be built in a kernel that supports different kinds of dmaengine drivers. - Consistency with other subsystems and drivers On the other hand, we have a few downsides: - The s3c24xx-dma driver now needs to be built-in for the ac97 platform device to be instantiated on s3c2440. - samsung_dmaengine_pcm_config cannot be marked 'const' any more because the filter function pointer needs to be set at runtime. This is safe as long we don't have multiple different DMA engines in thet same system at runtime, but is nonetheless ugly.

Note that on s3c64xx, the pl08x DMA data is already a pointer, but gets cast to resource_size_t so we can pass it as a resource, and it then gets converted back to a pointer. In contrast, the data we pass for s3c24xx is an index into a device specific table, and we artificially convert that into a pointer for the filter function.

2015-07-28ARM: kill off set_irq_flags usageRob Herring
set_irq_flags is ARM specific with custom flags which have genirq equivalents. Convert drivers to use the genirq interfaces directly, so we can kill off set_irq_flags. The translation of flags is as follows: IRQF_VALID -> !IRQ_NOREQUEST IRQF_PROBE -> !IRQ_NOPROBE IRQF_NOAUTOEN -> IRQ_NOAUTOEN For IRQs managed by an irqdomain, the irqdomain core code handles clearing and setting IRQ_NOREQUEST already, so there is no need to do this in .map() functions and we can simply remove the set_irq_flags calls. Some users also modify IRQ_NOPROBE and this has been maintained although it is not clear that is really needed. There appears to be a great deal of blind copy and paste of this code.

The only place where the time is invalid is when the ACPI_CSTATE_FFH entry method is not set. Otherwise for all the drivers, the time can be correctly measured. Instead of duplicating the CPUIDLE_FLAG_TIME_VALID flag in all the drivers for all the states, just invert the logic by replacing it by the flag CPUIDLE_FLAG_TIME_INVALID, hence we can set this flag only for the acpi idle driver, remove the former flag from all the drivers and invert the logic with this flag in the different governor.
