ALTERNATE

#define ALTERNATE   0x0 /* Alternate function output */

Pin modes.

ANALOG

#define ANALOG   0x2 /* Analog */

#define GPIO_OUT   0x3 /* Output */

STM32_LINE_MASK

STM32_LINE_SHIFT

#define STM32_LINE_SHIFT   2U

#define STM32_MODE_SHIFT   0U

Originally derived from Linux: include/dt-bindings/pinctrl/stm32-pinfunc.h.

For compatibility with Linux, the STM32_PINMUX macro and pinmux property have been retained. However, the resulting value is not saved as-is inside the image: during compilation, information is extracted from pinmux and saved in a custom format (c.f. soc/st/stm32/common/pinctrl_soc.h)

Macro to generate pinmux int using port, pin number and mode arguments This is adapted from Linux equivalent st,stm32f429-pinctrl binding

STM32_PORT_MASK

#define STM32_PORT_MASK   0xFU

STM32_PORT_SHIFT

#define STM32_PORT_SHIFT   6U

STM32_REMAP_MASK

#define STM32_REMAP_MASK   0x3FFU

STM32_REMAP_SHIFT

#define STM32_REMAP_SHIFT   10U

STM32F1_PINMUX

#define STM32F1_PINMUX	(		port,
			line,
			mode,
			remap )

Value:

(((((port) - 'A') & STM32_PORT_MASK) << STM32_PORT_SHIFT) |    \
(((line) & STM32_LINE_MASK) << STM32_LINE_SHIFT) |             \
(((mode) & STM32_MODE_MASK) << STM32_MODE_SHIFT) |             \
(((remap) & STM32_REMAP_MASK) << STM32_REMAP_SHIFT))

Pin configuration configuration bit field.

Fields:

• mode [ 0 : 1 ]
• line [ 2 : 5 ]
• port [ 6 : 9 ]
• remap [ 10 : 19 ]

Parameters

port	Port ('A'..'K')
line	Pin (0..15)
mode	Pin mode (ANALOG, GPIO_IN, GPIO_OUT, ALTERNATE).
remap	Pin remapping configuration (NO_REMAP, REMAP_1, ...)
