pinctrl: bcm281xx: Use "unsigned int" instead of bare "unsigned"

2025-05-29T09:02:30+00:00

[ Upstream commit 07b5a2a13f4704c5eae3be7277ec54ffdba45f72 ] Replace uses of bare "unsigned" with "unsigned int" to fix checkpatch warnings. No functional change.

pinctrl: bcm281xx: Fix incorrect regmap max_registers value

2025-03-22T19:54:09+00:00

[ Upstream commit 68283c1cb573143c0b7515e93206f3503616bc10 ] The max_registers value does not take into consideration the stride; currently, it's set to the number of the last pin, but this does not accurately represent the final register. Fix this by multiplying the current value by 4.

pinctrl: bcm2835: Fix permissions of persist_gpio_outputs

2024-06-17T07:49:36+00:00

The commit 8ff05989b44e ("pinctrl: bcm2835: Make pin freeing behavior configurable") unintentionally made the module parameter persist_gpio_outputs changeable at runtime. So drop the write permission in order to make the freeing behavior predictable for user applications.

pinctrl: bcm2835: Make pin freeing behavior configurable

2024-05-06T06:14:01+00:00

Until now after a bcm2835 pin was freed its pinmux was set to GPIO_IN. So in case it was configured as GPIO_OUT before the configured output level also get lost. As long as GPIO sysfs was used this wasn't actually a problem because the pins and their possible output level were kept by sysfs. Since more and more Raspberry Pi users start using libgpiod they are confused about this behavior. So make the pin freeing behavior of GPIO_OUT configurable via module parameter. In case pinctrl-bcm2835.persist_gpio_outputs is set to 1, the output level is kept. This patch based on the downstream work of Phil Elwell.

pinctrl: bcm2835: Implement bcm2711_pinconf_get

2024-03-28T08:52:25+00:00

The BCM2711 allows to read the bias config. So implement pin_conf_get accordingly. The pull resistor values has been taken from the BCM2711/7211 datasheet. This implementation assumes that BCM7211 behaves the same way.
