STM32_AF0

#define STM32_AF0   0x0

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 inspired from Linux equivalent st,stm32f429-pinctrl binding.

STM32_PINMUX

#define STM32_PINMUX	(		port,
			line,
			mode )

Value:

(((((port) - 'A') & STM32_PORT_MASK) << STM32_PORT_SHIFT) |    \
(((line) & STM32_LINE_MASK) << STM32_LINE_SHIFT) |             \
(((STM32_ ## mode) & STM32_MODE_MASK) << STM32_MODE_SHIFT))

Pin configuration configuration bit field.

Fields:

• mode [ 0 : 4 ]
• line [ 5 : 8 ]
• port [ 9 : 13 ]

Parameters

port	Port ('A'..'Q', 'Z')
line	Pin (0..15)
mode	Mode (ANALOG, GPIO, ALTERNATE).

STM32_PORT_MASK

#define STM32_PORT_MASK   0x1FU

STM32_PORT_SHIFT

#define STM32_PORT_SHIFT   9U
