Thank you!
Hi Linus, here is the bulk of GPIO changes for the v5.10 kernel. This time very little driver changes but lots of core changes. Details in the signed tag. We have some interesting cooperative work for ARM and Intel alike, making the GPIO subsystem more and more suitable for industrial systems and the like, in addition to the in-kernel users. We touch driver core (device properties) and lib/* by adding one simple string array free function, these are authored by Andy Shevchenko who is a well known and recognized core helpers maintainers so this should be fine. We also see some Android GKI-related modularization in the MXC drivers. I foresee a merge conflict in drivers/gpio/gpio-mockup.c due to things merged into the release candidate. The merge should be trivial and pertains to using pr_fmt and numerical return values: what's on my branch goes and that is also the resolution you find in linux-next. Please pull it in! Yours, Linus Walleij The following changes since commit 9123e3a74ec7b934a4a099e98af6a61c2f80bbf5: Linux 5.9-rc1 (2020-08-16 13:04:57 -0700) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio.git tags/gpio-v5.10-1 for you to fetch changes up to fc709df553a34fd18010f52e6b47652268d83e7d: gpiolib: Update header block in gpiolib-cdev.h (2020-10-08 22:57:16 +0200) ---------------------------------------------------------------- GPIO bulk changes for the v5.10 kernel cycle: Core changes: - The big core change is the updated (v2) userspace character device API. This corrects badly designed 64-bit alignment around the line events. We also add the debounce request feature. This echoes the often quotes passage from Frederick Brooks "The mythical man-month" to always throw one away, which we have seen before in things such as V4L2. So we put in a new one and deprecate and obsolete the old one. - All example tools in tools/gpio/* are migrated to the new API to set a good example. The libgpiod userspace library has been augmented to use this new API pretty much from day 1. - Some misc API hardening by using strn* function calls has been added as well. - Use the simpler IDA interface for GPIO chip instance enumeration. - Add device core function for counting string arrays in device properties. - Provide a generic library function kfree_strarray() that can be used throughout the kernel. Driver enhancements: - The DesignWare dwapb-gpio driver has been enhanced and now uses the IRQ handling in the gpiolib core. - The mockup and aggregator drivers have seen some substantial code clean-up and now use more of the core kernel inftrastructure. - Misc cleanups using dev_err_probe(). - The MXC drivers (Freescale/NXP) can now be built modularized, which makes modularized GKI Android kernels happy. ---------------------------------------------------------------- Aleksander Jan Bajkowski (1): gpio: stp-xway: automatically drive GPHY leds on ar10 and grx390 Andy Shevchenko (3): gpio: aggregator: Refactor ->{get, set}_multiple() to make Sparse happy gpiolib: convert to use DEFINE_SEQ_ATTRIBUTE macro gpiolib: Update header block in gpiolib-cdev.h Anson Huang (1): gpio: mxc: Support module build Bartosz Golaszewski (16): gpiolib: switch to simpler IDA interface device: property: add helpers to count items in string arrays gpiolib: generalize devprop_gpiochip_set_names() for device properties gpiolib: unexport devprop_gpiochip_set_names() gpiolib: check for parent device in devprop_gpiochip_set_names() gpio: mockup: fix resource leak in error path lib: string_helpers: provide kfree_strarray() Documentation: gpio: add documentation for gpio-mockup gpio: mockup: drop unneeded includes gpio: mockup: use KBUILD_MODNAME gpio: mockup: use pr_fmt() gpio: mockup: remove unneeded return statement gpio: mockup: increase the number of supported device properties gpio: mockup: pass the chip label as device property gpio: mockup: use the generic 'gpio-line-names' property gpio: mockup: refactor the module init function Kent Gibson (21): gpiolib: cdev: gpio_desc_to_lineinfo() should set info offset gpiolib: cdev: replace strncpy() with strscpy() gpio: uapi: define GPIO_MAX_NAME_SIZE for array sizes gpio: uapi: define uAPI v2 gpiolib: make cdev a build option gpiolib: add build option for CDEV v1 ABI gpiolib: cdev: support GPIO_V2_GET_LINE_IOCTL and GPIO_V2_LINE_GET_VALUES_IOCTL gpiolib: cdev: support GPIO_V2_GET_LINEINFO_IOCTL and GPIO_V2_GET_LINEINFO_WATCH_IOCTL gpiolib: cdev: support edge detection for uAPI v2 gpiolib: cdev: support GPIO_V2_LINE_SET_CONFIG_IOCTL gpiolib: cdev: support GPIO_V2_LINE_SET_VALUES_IOCTL gpiolib: cdev: support setting debounce gpio: uapi: document uAPI v1 as deprecated tools: gpio: port lsgpio to v2 uAPI tools: gpio: port gpio-watch to v2 uAPI tools: gpio: rename nlines to num_lines tools: gpio: port gpio-hammer to v2 uAPI tools: gpio: port gpio-event-mon to v2 uAPI tools: gpio: add multi-line monitoring to gpio-event-mon tools: gpio: add debounce support to gpio-event-mon gpiolib: cdev: switch from kstrdup() to kstrndup() Krzysztof Kozlowski (15): gpio: bcm-kona: Simplify with dev_err_probe() gpio: davinci: Simplify with dev_err_probe() gpio: omap: Simplify with dev_err_probe() gpio: pca953x: Simplify with dev_err_probe() gpio: pisosr: Simplify with dev_err_probe() gpio: zynq: Simplify with dev_err_probe() dt-bindings: gpio: fsl-imx-gpio: Add i.MX 8 compatibles dt-bindings: gpio: fsl-imx-gpio: Add gpio-ranges property dt-bindings: gpio: fsl-imx-gpio: Add parsing of hogs dt-bindings: gpio: fsl-imx-gpio: Add power-domains dt-bindings: gpio: pl061: add gpio-line-names dt-bindings: gpio: fsl-imx-gpio: add i.MX ARMv6 and ARMv7 compatibles dt-bindings: gpio: fsl-imx-gpio: add gpio-line-names dt-bindings: gpio: convert bindings for NXP PCA953x family to dtschema dt-bindings: gpio: convert bindings for Maxim MAX732x family to dtschema Lad Prabhakar (1): dt-bindings: gpio: renesas, rcar-gpio: Add r8a774e1 support Linus Walleij (3): Merge tag 'imx-gpio-5.10' of https://git.kernel.org/.../krzk/linux into devel Merge tag 'gpio-updates-for-v5.10-part1' of git://git.kernel.org/.../brgl/linux into devel Merge tag 'gpio-updates-for-v5.10-part2' of git://git.kernel.org/.../brgl/linux into devel Mauro Carvalho Chehab (1): docs: gpio: add a new document to its index.rst Michael Walle (1): gpio: mpc8xxx: simplify ls1028a/ls1088a support Mike Looijmans (1): gpio: pca953x: Add support for the NXP PCAL9554B/C Necip Fazil Yildiran (1): pinctrl: bcm: fix kconfig dependency warning when !GPIOLIB Serge Semin (10): dt-bindings: gpio: dwapb: Add ngpios property support gpio: dwapb: Add ngpios DT-property support gpio: dwapb: Move MFD-specific IRQ handler gpio: dwapb: Add max GPIOs macro gpio: dwapb: Convert driver to using the GPIO-lib-based IRQ-chip gpio: dwapb: Discard GPIO-to-IRQ mapping function gpio: dwapb: Discard ACPI GPIO-chip IRQs request gpio: dwapb: Get reset control by means of resource managed interface gpio: dwapb: Get clocks by means of resource managed interface gpio: dwapb: Use resource managed GPIO-chip add data method dillon min (1): gpio: tc35894: Disable Direct KBD interrupts to enable gpio irq Documentation/admin-guide/gpio/gpio-mockup.rst | 50 + Documentation/admin-guide/gpio/index.rst | 1 + .../devicetree/bindings/gpio/fsl-imx-gpio.yaml | 55 +- .../devicetree/bindings/gpio/gpio-max732x.txt | 58 -
