We have more lines removed than added thanks to dropping of a driver for a platform that's no longer supported. Otherwise the changes are pretty straightforward: support for some new models, various improvements to existing drivers, some tweaks to the core library code and DT bindings updates. Summary: - remove gpio-vr41xx driver as the only platform using it got dropped too - add support for suspend/resume to gpio-davinci - improvements to the GPIO character device code - add support for disabling bias for in-kernel users (up until now only user-space could set it) - drop unused devm_gpio_free() - fix a refcount issue in gpiolib OF - use device match helpers where applicable - add support for a new model to gpio-rockchip - non-functional improvements in gpio-adp5588 - improve and simplify teardown in gpio-twl4030 and gpio-ucb1400 - modernize the gpio-74xx-mmio and gpio-adnp drivers - coding style improvements in gpio-xilinx, gpio-104-idi-48 - support new model (pca9571) in gpio-pca9570 - convert the DT bindings to YAML for gpio-mvebu and update the document - don't return error codes from remove() in gpio-brcmstb - add a library for the intel 8255 PPI interface and use it in drivers - reduce using magic numbers and improve code readability in several drivers - convert DT bindings to YAML for gpio-tpic2810 - add new models to DT bindings for gpio-frl-imx - Kconfig improvements - other minor tweaks and improvements" * tag 'gpio-updates-for-v6.0-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux: (52 commits) dt-bindings: gpio: fsl-imx-gpio: Add i.MXRT compatibles gpio: 74xx-mmio: Use bits instead of plain numbers for flags gpio: xilinx: add missing blank line after declarations MAINTAINERS: Update Intel 8255 GPIO driver file list gpio: gpio-mm: Implement and utilize register structures gpio: 104-idi-48: Implement and utilize register structures gpio: 104-dio-48e: Implement and utilize register structures gpio: i8255: Introduce the Intel 8255 interface library module gpio: 104-idio-16: Implement and utilize register structures gpio: ws16c48: Implement and utilize register structures gpio: remove VR41XX related gpio driver dt-bindings: gpio: add pull-disable flag gpiolib: acpi: support bias pull disable gpiolib: of: support bias pull disable gpiolib: add support for bias pull disable gpio: 74xx-mmio: use bits.h macros for all masks gpio: 74xx-mmio: Check MMIO_74XX_DIR_IN flag in mmio_74xx_dir_in() gpio: 74xx-mmio: Make use of device properties gpiolib: cdev: compile out HTE unless CONFIG_HTE selected gpiolib: cdev: consolidate edge detector configuration flags ...

| | | | | | | | | | | | | | | | | | | | | | | | The initial code was misleading to use bitwise AND against plain number, and the commit d3054ba1db62 ("gpio: 74xx-mmio: Check MMIO_74XX_DIR_IN flag in mmio_74xx_dir_in()") missed that.

| * gpio: i8255: Introduce the Intel 8255 interface library moduleWilliam Breathitt Gray2022-07-204-0/+346
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Exposes consumer library functions providing support for interfaces compatible with the venerable Intel 8255 Programmable Peripheral Interface (PPI). The Intel 8255 PPI first appeared in the early 1970s, initially for the Intel 8080 and later appearing in the original IBM-PC. The popularity of the original Intel 8255 chip led to many subsequent variants and clones of the interface in various chips and integrated circuits. Although still popular, interfaces compatible with the Intel 8255 PPI are nowdays typically found embedded in larger VLSI processing chips and FPGA components rather than as discrete ICs. A CONFIG_GPIO_I8255 Kconfig option is introduced by this patch. Modules wanting access to these i8255 library functions should select this Kconfig option, and import the I8255 symbol namespace.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Combine the polarity_change flag, struct line eflags, and hte enable flag into a single flag variable. The combination of these flags describes the configuration state of the edge detector, so formalize and clarify that by combining them into a single variable, edflags, in struct line. The edflags is a subset of the GPIO_V2_LINE_FLAGsb relevant to the edge detector, and is also a superset of the eflags it replaces. The eflags name is still used to describe the subset of edflags corresponding to the rising/falling edge flags where edflags is masked down to that subset. This consolidation reduces the number of variables being passed, simplifies state comparisons, and provides a more extensible foundation should additional edge sources be integrated in the future.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We should use of_node_get() when a new reference of device_node is created. It is noted that the old reference stored in 'mm_gc->gc.of_node' should also be decreased. This patch is based on the fact that there is a call site in function 'qe_add_gpiochips()' of src file 'drivers\soc\fsl\qe\gpio.c'. In this function, of_mm_gpiochip_add_data() is contained in an iteration of for_each_compatible_node() which will automatically increase and decrease the refcount. So we need additional of_node_get() for the reference escape in of_mm_gpiochip_add_data().

| * | gpio: ucb1400: Remove platform setup and teardown supportUwe Kleine-König2022-07-191-20/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is no user of these callbacks. The motivation for this change is to stop returning an error code from the remove callback. This is a preparation for making platform remove callbacks return void. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Signed-off-by: Bartosz Golaszewski <brgl@bgdev.pl>
| * | gpio: twl4030: Don't return an error after WARN in .removeUwe Kleine-König2022-07-191-5/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Returning a non-zero value in a platform driver's remove callback only results in an error message ("remove callback returned a non-zero value. This will be ignored.", see platform_remove()), and then the device is removed anyhow. As there was just a WARN_ON triggered, return 0 to drop the follow up warning. The latter output is hardly relevant after the big WARN splat. This is a preparation for making platform remove callbacks return void.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The last user, which in fact was a dead code, has gone a year ago, previous one 3 years ago. On top of that we want to drop away the legacy GPIO APIs in the kernel, so take a chance to get rid of unused devm_gpio_free() and accompanying stuff.

It is also architecture specific, and breaks compilation in a pretty bad way now that linux/gpio/driver.h includes asm/msi.h (which drags a conflicting but nonetheless correct version of msi_alloc_info_t on x86).
