Merge tag 'gpio-updates-for-v6.4' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux
Pull gpio updates from Bartosz Golaszewski: "We have some new drivers, significant refactoring of existing intel platforms, lots of improvements all around, mass conversion to using immutable irqchips by drivers that had not been converted individually yet and some changes in the core library code. Summary: New drivers: - add a driver for the Loongson GPIO controller - add a driver for the fxl6408 I2C GPIO expander - add a GPIO module containing code common for Intel Elkhart Lake and Merrifield platforms - add a driver for the Intel Elkhart Lake platform reusing the code from the intel tangier library GPIOLIB core: - GPIO ACPI improvements - simplify gpiochip_add_data_with_keys() fwnode handling - cleanup header inclusions (remove unneeded ones, order the rest alphabetically) - remove duplicate code (reuse krealloc() instead of open-coding it, drop a duplicated check in gpiod_find_and_request()) - reshuffle the code to remove unnecessary forward declarations - coding style cleanups and improvements - add a helper for accessing device fwnodes - small updates in docs Driver improvements: - convert all remaining GPIO irqchip drivers to using immutable irqchips - drop unnecessary of_match_ptr() macro expansions - shrink the code in gpio-merrifield significantly by reusing the code from gpio-tangier + minor tweaks to the driver code - remove MODULE_LICENSE() from drivers that can only be built-in - add device-tree support to gpio-loongson1 - use new regmap features in gpio-104-dio-48e and gpio-pcie-idio-24 - minor tweaks and fixes to gpio-xra1403, gpio-sim, gpio-tegra194, gpio-omap, gpio-aspeed, gpio-raspberrypi-exp - shrink code in gpio-ich and gpio-pxa - Kconfig tweak for gpio-pmic-eic-sprd" * tag 'gpio-updates-for-v6.4' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux: (99 commits) gpio: gpiolib: Simplify gpiochip_add_data_with_key() fwnode gpiolib: Add gpiochip_set_data() helper gpiolib: Move gpiochip_get_data() higher in the code gpiolib: Check array_info for NULL only once in gpiod_get_array() gpiolib: Replace open coded krealloc() gpiolib: acpi: Add a ignore wakeup quirk for Clevo NL5xNU gpiolib: acpi: Move ACPI device NULL check to acpi_get_driver_gpio_data() gpiolib: acpi: use the fwnode in acpi_gpiochip_find() gpio: mm-lantiq: Fix typo in the newly added header filename sh: mach-x3proto: Add missing #include <linux/gpio/driver.h> powerpc/40x: Add missing select OF_GPIO_MM_GPIOCHIP gpio: xlp: Convert to immutable irq_chip gpio: xilinx: Convert to immutable irq_chip gpio: xgs-iproc: Convert to immutable irq_chip gpio: visconti: Convert to immutable irq_chip gpio: tqmx86: Convert to immutable irq_chip gpio: thunderx: Convert to immutable irq_chip gpio: stmpe: Convert to immutable irq_chip gpio: siox: Convert to immutable irq_chip gpio: rda: Convert to immutable irq_chip ...

-从内核代码中导出
-----------------
-
-内核代码可以明确地管理那些已通过 gpio_request()申请的 GPIO 的导出::
-
- /* 导出 GPIO 到用户空间 */
- int gpio_export(unsigned gpio, bool direction_may_change);
-
- /* gpio_export()的逆操作 */
- void gpio_unexport();
-
-在一个内核驱动申请一个 GPIO 之后,它可以通过 gpio_export()使其在 sysfs
-接口中可见。该驱动可以控制信号方向是否可修改。这有助于防止用户空间代码无意间
-破坏重要的系统状态。
-
-这个明确的导出有助于(通过使某些实验更容易来)调试,也可以提供一个始终存在的接口,
-与文档配合作为板级支持包的一部分。
