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

2025-06-04T12:40:09+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

2025-03-28T20:58:48+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: Handle gpiochip_add_pin_range() errors

pinctrl-bcm2835.c: fix race condition when setting gpio dir

2023-05-11T14:03:37+00:00

[ Upstream commit b7badd752de05312fdb1aeb388480f706d0c087f ] In the past setting the pin direction called pinctrl_gpio_direction() which uses a mutex to serialize this. That was changed to set the direction directly in the pin controller driver, but that lost the serialization mechanism. Since the direction of multiple pins are in the same register you can have a race condition, something that was in fact observed with the cec-gpio driver. Add a new spinlock to serialize writing to the FSEL registers.
