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 ...

As we want to give gpio_chip:s real devices, this is not working. We need to rename this member to parent. This was done by two coccinelle scripts, I guess it is possible to combine them into one, but I don't know such stuff. They look like this: @@ struct gpio_chip *var; @@ -var->dev +var->parent and: @@ struct gpio_chip var; @@ -var.dev +var.parent and: @@ struct bgpio_chip *var; @@ -var->gc.dev +var->gc.parent Plus a few instances of bgpio that I couldn't figure out how to teach Coccinelle to rewrite. This patch hits all over the place, but I *strongly* prefer this solution to any piecemal approaches that just exercise patch mechanics all over the place. It mainly hits drivers/gpio and drivers/pinctrl which is my own backyard anyway.

Notably I have a patch to driver core from Stephen Boyd in the pull request, this has been ACKed by Greg so it should be OK. The internal API needed some tweaking to allow modular Qualcomm pin controllers. There is a bit of development history in here but it should all add up nicely and has boiled in linux-next. For example I merged in v4.4-rc5 to get rid of some nasty merge conflicts. Summary: - New drivers: - PXA2xx pin controller support - Broadcom NSP pin controller support - New subdrivers: - Samsung EXYNOS5410 support - Qualcomm MSM8996 support - Qualcomm PM8994 support - Qualcomm PM8994 MPP support - Allwinner sunxi H3 support - Allwinner sunxi A80 support - Rockchip RK3228 support - Rename the Cygnus pinctrl driver to "iproc" as it is more generic than was originally thought. - A bunch of Lantiq/Xway updates especially from the OpenWRT people. - Several refactorings for the Super-H SH PFC pin controllers. Adding SCIF_CLK support. - Several fixes to the Atlas 7 driver. - Various fixes all over the place" * tag 'pinctrl-v4.5-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (91 commits) pinctrl: mediatek: Modify pinctrl bindings for mt2701 Revert "pinctrl: qcom: make PMIC drivers bool" pinctrl: qcom: Use platform_irq_count() instead of of_irq_count() driver-core: platform: Add platform_irq_count() pinctrl: lantiq: 2 pins have the wrong mux list pinctrl: qcom: make PMIC drivers bool pinctrl: nsp-gpio: forever loop in nsp_gpio_get_strength() pinctrl: mediatek: convert to arch_initcall pinctrl: bcm2835: Fix memory leak in error path pinctrl: mediatek: add missing of_node_put pinctrl: rockchip: add missing of_node_put pinctrl: sh-pfc: add missing of_node_put pinctrl: sirf: add missing of_node_put pinctrl-tegra: add missing of_node_put pinctrl: sunxi: Add A80 special pin controller pinctrl: bcm/cygnys/iproc: fixup rebase issue pinctrl: fixup problematic flag MAINTAINERS: Add co-maintainer for Renesas Pin Controllers pinctrl: sh-pfc: r8a7791: add EtherAVB pin groups pinctrl: sh-pfc: r8a7795: Add SATA support ...
