Avoid kernel.h inclusion where it's possible. Besides that, clean up a bit other inclusions inside GPIO subsystem headers. It includes: - removal pin control bits (forward declaration and header) from linux/gpio.h - removal of.h from asm-generic/gpio.h - use of explicit headers in gpio/consumer.h - add FIXME note with regard to gpio.h inclusion in of_gpio,h Signed-off-by: Andy Shevchenko --- v2: Elaborate changes in the commit message (Bartosz) include/asm-generic/gpio.h | 4 ++-- include/linux/gpio.h | 2 -- include/linux/gpio/consumer.h | 5 ++++- include/linux/of_gpio.h | 9 ++++++--- 4 files changed, 12 insertions(+), 8 deletions(-) diff --git a/include/asm-generic/gpio.h b/include/asm-generic/gpio.h index 19eadac415c4..aea9aee1f3e9 100644 --- a/include/asm-generic/gpio.h +++ b/include/asm-generic/gpio.h @@ -2,10 +2,8 @@ #ifndef _ASM_GENERIC_GPIO_H #define _ASM_GENERIC_GPIO_H -#include #include #include -#include #ifdef CONFIG_GPIOLIB @@ -140,6 +138,8 @@ static inline void gpio_unexport(unsigned gpio) #else /* !CONFIG_GPIOLIB */ +#include + static inline bool gpio_is_valid(int number) { /* only non-negative numbers are valid */ diff --git a/include/linux/gpio.h b/include/linux/gpio.h index 2157717c2136..008ad3ee56b7 100644 --- a/include/linux/gpio.h +++ b/include/linux/gpio.h @@ -102,11 +102,9 @@ void devm_gpio_free(struct device *dev, unsigned int gpio); #include #include #include -#include struct device; struct gpio_chip; -struct pinctrl_dev; static inline bool gpio_is_valid(int number) { diff --git a/include/linux/gpio/consumer.h b/include/linux/gpio/consumer.h index bf2d017dd7b7..0a72fccf60ff 100644 --- a/include/linux/gpio/consumer.h +++ b/include/linux/gpio/consumer.h @@ -2,9 +2,10 @@ #ifndef __LINUX_GPIO_CONSUMER_H #define __LINUX_GPIO_CONSUMER_H +#include #include +#include #include -#include struct device; @@ -189,6 +190,8 @@ struct gpio_desc *devm_fwnode_gpiod_get_index(struct device *dev, #else /* CONFIG_GPIOLIB */ +#include + static inline int gpiod_count(struct device *dev, const char *con_id) { return 0; diff --git a/include/linux/of_gpio.h b/include/linux/of_gpio.h index 16967390a3fe..f821095218b0 100644 --- a/include/linux/of_gpio.h +++ b/include/linux/of_gpio.h @@ -11,9 +11,8 @@ #define __LINUX_OF_GPIO_H #include -#include -#include -#include +#include +#include /* FIXME: Shouldn't be here */ #include struct device_node; @@ -34,6 +33,8 @@ enum of_gpio_flags { #ifdef CONFIG_OF_GPIO +#include + /* * OF GPIO chip for memory mapped banks */ @@ -63,6 +64,8 @@ extern void of_mm_gpiochip_remove(struct of_mm_gpio_chip *mm_gc); #else /* CONFIG_OF_GPIO */ +#include + /* Drivers may not strictly depend on the GPIO support, so let them link. */ static inline int of_get_named_gpio_flags(struct device_node *np, const char *list_name, int index, enum of_gpio_flags *flags)
