pinctrl: bcm283x: Add GPIO pull-up/down control for BCM2835 and BCM2711 2025-11-25T09:22:12+00:00 Cibil Pankiras cibil.pankiras@egym.com 2025-11-13T23:45:32+00:00 2c39d975f87cfcce3805bff34918708bf7491b25 This patch adds support for configuring GPIO pull-up and pull-down resistors in the BCM283x pinctrl driver. It implements the brcm,pull device tree property to control pin bias settings. The implementation follows the hardware-specific pull control mechanisms: - BCM2835: two-step GPPUD register sequence - BCM2711: direct per-pin control registers This enables device tree configurations to specify pull-up, pull-down, or no bias for individual GPIO pins. Tested on Raspberry Pi boards with both BCM2835 and BCM2711 SoCs. Signed-off-by: Cibil Pankiras <cibil.pankiras@egym.com> Reviewed-by: Matthias Brugger <mbrugger@suse.com> 
This patch adds support for configuring GPIO pull-up and pull-down
resistors in the BCM283x pinctrl driver. It implements the brcm,pull
device tree property to control pin bias settings.

The implementation follows the hardware-specific pull control
mechanisms:

This enables device tree configurations to specify pull-up, pull-down,
